[majestytime]

thinking about satosugu summer roadtrip after they've died. they haven't passed on yet because they still have lingering regrets, but they're not quite ready to confront those feelings, not yet. so they're given a few months to drive across japan together. they know instinctively that this isn't the real world, that they're in some kind of limbo until the end of summer. but they ignore it for as long as possible.

traveling together, watching the sunrise, swimming at the beach, trying new foods and having new experiences at local places. staying up late, watching the stars, holding hands and kissing but never talking about it the next day. delaying the inevitable pain. making memories. enjoying their last blue spring together.

but all good things must come to an end. and eventually, they have to say goodbye to their past and present selves forever. these versions of them will never meet again, but they both hope that their next versions will meet again. they pray that they'll have a happy ending in another life. and that's where their story comes to an end.

Four Swords mutant/experiment AU

This is an AU I role played with @saltyskychild way back in like 2017, but I thought about it recently and wanted to retouch it!

TW: torture here and there, human experiments, general violence, blood, kidnapping

General plot: all four links are kidnapped/handed in to the government at a young age because they all posses superhuman abilities.

Each ability corresponds to the element acquainted with their color in the Zelda games: Blue - water, Red - fire, Green - air, Vio - earth.

Zelda is also a mutant, she hides this fact from her father who is the person that set out the order to capture and experiment on mutants.

She secretly runs an organization that helps rescue mutants from these facilities, with the help of Impa and other sheikah characters.

Shadow is a human experiment, he’s never seen the outside of the facility. The very first genetically engineered human weapon.

The colors are divided into danger levels (taking a page from: X-Men here LMAO).

Blue and Red are beta level because they’re the easiest to neutralize.

Red’s powers are neutralized by water of course.

Blue is neutralized by the cold, he freezes over faster than the average human because of the increased levels of water in his body.

Green is alpha level, he’s kept sedated because they can’t cut his oxygen aka his power source. If left unchecked he can raise air pressure levels and escape.

Vio and Shadow are omega level threats.

Vio’s power is simple but he’s smart, he figures out really quick that anything earth related or derived from earth is under his control, making the use of any metal around him prohibited.

Shadow is kept in a bright room, his room has two separate generators in case there is a power outage, he can’t be allowed in the darkness for too long or else he’ll grow too powerful.

Note that all colors have the potential to become omega level threats, they are all under strict surveillance because of it.

Vio was part of Zelda’s organization prior to being captured, therefore he has more experience with his powers than the others. He’s hostile, manipulative, only high level personnel are allowed to watch over him. He has a track record of talking his way into getting new employees to let him out.

This is how Zelda finds out about his facility, her informant (Vio) goes missing and she tracks it back to this facility and tries to rescue them all.

In Vio’s first escape attempt he uses the chance to see how many people are there, finding the other colors and deciding he has to make a plan that lets them all escape.

Along the way he sees Shadow, and Shadow becomes intrigued as soon as Vio nears his door and says “I promise I’ll get you out of here.”. No one has ever said that to him, everyone tells him he’ll be a weapon or rot in here.

Vio lets himself be recaptured, confident he can find another way to escape, hopefully to even contact Zelda. He could easily escape by himself, but abandoning these people here is cruel.

More notes to come if enough people take interest. Might write a fic too if people want it. Look forward to doodles about this AU as well.

Thinking of Yandere! Light with an enabler darling.

In order for this to work I think they'd have to meet at childhood, like in primary school or perhaps their parents would've been friends; because that's when kids have the most innocence and not understanding the true nature of the world.

I like to believe that even at a young age, Light would hold a dislike for those who did wrong. After all his father served in the police department, so it wouldn't be unusual to hear cases that are darker. Thus, leading him to mature more quickly than his peers. So imagine when he meets darling who doesn't understand human nature. As in the behavior and actions of a person, Light doesn't know this so he chose to believe darling is extremely sheltered and innocent.

So just imagine how it would be in secondary school, at this point you understood that Light was... more abnormal than the rest of your peers. Such as- Clings on to you, makes others feel inferior compared to you, uses "study sessions" as a way to hang out more, etc. Knowing this, you aren't afraid to use it and manipulate him, of course, he won't notice because how could you do such a thing? In his eyes, it's practically impossible, he's smarter so he would think he'd catch on quick. (He doesn't know you are fairly intelligent yourself...)

And oh boy do you really use that potential once he gets the book. When you find out, you act all shocked, and at first try to tell him he's wrong for killing people and that it's no better. This leaves him a way to think he can control you, he isn't afraid to change your beliefs to fit into his wants. So you act as if you gave in, praising him for removing the evil in the world, feeding into his ego. In fact, you convince him to kill certain people, people who wronged you? People who you just don't simply like? They'd be gone with a brutal death, after all, wouldn't it make them a bad person to hurt someone so innocent?

I want to add more but due to the fact I'm debating whether or not to write this as a one-shot or a series and whether not to include L in the shipping (because why not?) I don't want to reveal anything if it were to become a series. I also don't know if this fandom is dead on tumblr... So uh, if y'all want it comment to let me know your thoughts! (In any case you guys want to see how I write and whether or not you'd like it based on that, I have a csm post and a quotev account that's a Danganronpa fic! It's a Mikan x reader, called "You always forgave me..."!)

[cyrus-solaris]

okay y’all i had another ✨thought✨

and yes i’m still working on the chronic pain atsushi fic, dw i haven’t abandoned yall

but i read somewhere the other night that allegedly bc tigers have such good distance and night vision, their close up vision can be not so great.

do ik if this is 100% true? no.

did i take it and run with it anyways? of course.

so my brain went bad eyesight = glasses and atsushi is a tiger, so now atsushi wears glasses. but then my brain furthered it by going “when do you wear glasses? to read!!” so now may i humbly present you with:

glasses atsushi who is also a passionate reader

bc i personally headcanon that one of the only things he had access to at the orphanage was books and he discovered he could use them as a form of escapism, thus sparking his love of reading.

and now, if you’ll indulge my even further.

akutagawa finds out about the love of books by quite literally stumbling into atsushi outside of a book store (consequently making him drop all of his books and accidentally ruin one) and assists him with taking the books back to his place.

and akutagawa also replaces the book that got ruined and when he gives it to atsushi (via stopping by his place) he is met with atsushi in glasses.

and akutagawa realizes 2 things: 1) his rival/partner looks very cute in glasses and 2) akutagawa is very gay for him.

i have a much for fleshed out plan for this and have additionally scenes i will add in, but i’ll leave that up to y’all’s imaginations 😉

thoughts? feelings?

[hiorintruther]

Dragging myself out of inactivity to grossly overanalyse/scream about the chapter 213 Kunigiri stuff coz I’m so mentally unwell and it’s their fault.

First of all, I love how in order to get into the other stratums, players first have to submit a request form. Presumably they’d have to state a reason for going and I doubt “I want to see my friends” would be allowed because some people would end up using it as an excuse to slack off, so I wonder what Chigiri said to get his request accepted? Obviously he was actually coming just to see Kunigami but he probably needed to make up an excuse (either that or Ego/Anri let him through because BLTV really is just football Love Island atp).

Anyway, I love the intro panel for Chigiri in this chapter coz it says SO MUCH about him.

It’s the hair.

Chigiri barely ever wears his hair up, not even while playing football (and I’ve made my thoughts on that clear in the past so I’ll refrain from any ranting). On the field he’ll have that weird half-braid thing going on, and off the field he usually just wears it loose. One of the only other times we see him with a ponytail is in chapters 150-151, during the 2-week break post U-20 match. I think this shows that Chigiri is putting active effort into his appearance for his visit with Kunigami. He puts his hair up when he wants to make a good impression — in the Shibuya chapters he’s also wearing a rather nice outfit, so he was focussing on his appearance then too. This time around, he’s specifically doing it for Kunigami because he’s unsure about what Kunigami thinks of him after “ghosting” him during the MC match. This is Chigiri going all-out to impress through subtle gestures and small changes that are consciously made and will subconsciously be picked up on.

(There’s also Kunigami’s canonical thing for the napes of necks (egoist Bible) to take into account which… listen we have no proof that Chigiri is aware of it but we also don’t have any proof that he’s not. Who’s to say he didn’t choose this hairstyle specifically because he knows it shows off his nape, which is usually kept hidden under his hair? He’s already a bit of a flirt after that “such an insensitive hero” comment back during the Second Selection. It isn’t impossible.)

Next, the iconic “keep an eye on me” line.

First off, Nomura really decided to make Chigiri look that pretty when he said this. Boy looks absolutely gorgeous. I’m aroace but I would’ve folded. Kunigami is stronger than me.

Second off, I like how this shows Chigiri being attentive towards Kunigami. When they first reunited, it did come across a bit like Chigiri was being dismissive of what Kunigami went through in the Wildcard, saying that he’d treat Kunigami as exactly the same person he was before (although it’s arguably understandable since they’d only just met again and Chigiri has no idea what happened in the Wildcard). Now though, it’s clear he’s observed the change Kunigami went through and a) wants to make amends for his previous comments, and b) still wants to be with Kunigami. While there’s never a direct apology given, it’s clear he doesn’t think of Kunigami the same way he did before the Mc match and wants to make amends. Honestly, idk if a direct apology would’ve been a nice addition or would’ve just made Kunigami feel worse — Chigiri is a proud person and Kunigami doesn’t want pity, so this less direct approach was probably the best way to go about things.

Thirdly, when Chigiri says “from now on, I’m gonna be keeping an eye on you”, it’s not just a promise to acknowledge Kunigami’s skills as a footballer. It’s also a subtle way of saying “you’re not getting rid of me. I’m staying right here”. Adding to that the “so, you better keep an eye on me too, got it?”, it’s both a declaration that Kunigami shouldn’t underestimate Chigiri and a “you’re gonna be seeing a lot of me so get used to it”. (Side note: Isagi’s face on this page is so fucking funny to me he’s just like “yeaaaaaah, these bitches gay. Good for them” lmao.)

Last thing I’ll scream about is this:

FIRST NAME BASIS!!!

Obviously Chigiri is specifically using “Rensuke” as a little jab at Kunigami to get him riled up. Chigiri is just like that when it comes to teasing. Still, it’s nice to know that he feels comfortable enough around Kunigami to say something like this without Kunigami getting angry or making things awkward between them. We’ve seen Bachira do this with Isagi too during the Barcha match, so that’s nice little bachisagi parallel. At the very least, Chigiri is showing that he wants their friendship to continue and is going to continue to treat Kunigami as a close friend, no matter how much Kunigami might try to push him away.

Conclusion to my ramblings: Chigiri is putting in the work and I respect him for it. Kunigami is in a bad place rn and what he needs is someone as stubborn as Chigiri to see him through. Chigiri knows what it feels like to feel depressed and push everyone else away because it happened to him too. He thought for a time that everything was over for him. No doubt he’s recognising those things in Kunigami and wants to help him out, especially since the two of them had grown pretty close before being separated.

Kunigiri has my whole heart!!!

[robin-with-a-pen]

Okay I’m having ideas I need someone to stop me-

Anyways, so we all know that Chilchuck probably doesn’t have the healthiest relationship with food? Right?

I don’t think he has an eating disorder but more so disordered eating- that hellish middle space, right? I mean “maintaining his body weight at an acceptable level” really sticks out to me

So picture this- my man retires, he doesn’t need to control his weight anymore, no worry about setting off or anything, but he realizes that the unhealthy habits he’s developed over he past ten years are harder to break than he thought

[zyannsworld]

It was the worst day for Zoro’s heart as he learned his mate was kidnapped, marrying someone else, and perhaps never going to see him again. Taking his frustration on others was the only thing to keep himself from shading tears

Guess who rewatched Zou arc? 😭

[artytaeh]

for the dearest headcanon writers .ᐟ

fear not, in case you're bored, here's some

suggestions of headcanons you could write

about! ( and that i personally would love to read

about, but shh. )

𐀔 with a s/o that frequently hides behind them and peaks over their shoulder. could be out of shyness or because she's surrounded by people she's hesitant about.

𐀔 type of date they like the most. maybe a headcanon about where they would like to go on a date, where they would have fun, if they'd think too much about it, for how long the date would go on, if they take them home, etc.

𐀔 when travelling with s/o. are they the ones who plan everything? or do they go with an unplanned schedule? which transport they'd like the most, and to go where? stuff about hotels and shopping would be fun to talk about too.

𐀔 with a s/o that is a perfeccionist about their hobbies. could be something about painting, playing any instrument, dancing, writing, etc. could be about them both being their #0 stans but also helping s/o cope with not being satisfied with the 'product' (painting, choreography, etc!) of their hobby.

𐀔 with a s/o who's avoidant with problems. here you could go 2 ways: a) s/o hates conflict so the relationship becomes a little bitter for their avoidance of 'fighting' or trying to solve the problem; or b) s/o that runs away from her problems. she's too scared to go out to do something? she doesn't go. so the partner helps the s/o dealing with this.

𐀔 when they use glasses, and s/o thinks it's attractive. hear me out; a character who usually doesn't wear glasses, only on rare occasions (to read, for example!) and s/o simps over it.

𐀔 with a s/o that has a style totally opposite of them. for example, if the character uses darker colors = s/o wears lighter colors. how would they react? do they think it's a funny thing?

𐀔 moving together with their s/o. who took the initiative to suggest them moving together? unpacking, their first night sleeping on their bedroom, settling rules / sharing tasks...

𐀔 when the group asks reader who would be the best partner out of them, and reader answers their name. it could be the reader's opinion about who would be the best partner, or who matches reader's ideal type the most. it would be funny to see the character's reaction, and if they would act on it or not.

𐀔 and the petnames they'd used with their s/o. do they still call s/o by their name? which kind of petnames are they fond of? maybe include ones that they'd like to be called as, too!

𐀔 with a reader whose love language is physical touch, and ask character to hold their hand / for a hug. this would be before reader is their s/o, this also being the first time that reader asks to be comforted or held by them as well.

𐀔 with a reader that constantly has nightmares, and is afraid to be alone afterwards. how would they react when reader calls for them? what would they do to sooth / help reader to avoid nightmares?

𐀔 when they plan a date / surprise for reader, but they didn't know so on that day, they hang out with other people.

𐀔 with a reader who has arachnophobia. as someone who has this, i promise you that this is awful and that i need someone who acts like my knight in shining armor about this.

𐀔 with a reader who has claustrophobia and they end up stuck inside a small room. for my claustrophobic moots. </3

𐀔 with a reader who was hit with an ability / spell that makes her eyes change color according to their feelings. reader is angry? red eyes. reader is sad? blue eyes. reader is flustered and shy? pink eyes. reader can't lie about their emotions now, would the character take advantage of this?

𐀔 with a reader who secretly has a nerdy side, and could talk about their favorite thing (animal, anime, series, book, game, etc) for hours.

𐀔 with a reader who is a picky eater. would they help reader with this, or would they complain about it?

this is all i could think of right now,

but if i get more ideas, i'll post another

one of these in hopes that some

writer will post headcanons about

these. 🎀

Came up with a Spy X Family AU idea - the Occupation Swap!AU.

Basically Yor is a spy and Loid is an assassin.

Coming up with new code names was hard, but I'm thinking Yor's should be "Vesper" and Loid's is "Thistle".

Working on sketches and possibly a fanfic for this AU, stay tuned!

[granny-griffin]

midoriya izuku obviously forgives bakugou for everything—he doesn’t take himself into account + he’s already been actively forgiving him since like episode one. but you know who else was around to experience the effects of bakugou’s behavior and coincidentally does nothing but take izuku into account?? midoriya inko

hey guys how do you think inko feels about the mech suit? Izuku did become a hero, and then even though he quit the profession he was still relatively famous and respected as a hero + he got to follow in all might’s footsteps working at U.A. and even if he had some regrets he was happy and he was safe. And then Bakugou & co came and found a way for him to go back to doing dangerous things

hey isn’t it great that bakugou worked so hard because he believed that midoriya could be a hero—now that all might and his classmates and tech workers in various countries all agree? hey—why couldn’t that have happened sooner, back when bakugou was his only friend and even inko herself didn’t believe in midoriya’s dream? 

and how would inko react if she found out that bakugou has believed izuku would be a hero ever since they were four, when izuku held out his hand and he saw all might in the act—but instead of saying the one thing izuku needed to hear, the thing only he in all the world could say and mean, he spent 10-ish years trying to keep izuku from finding out, trying to bury the knowledge even from himself?

do you think bakugou apologized to inko also? do you think it occured to him that he might need to? would she forgive him if he did? would she be able to look izuku in the face if she didn’t?

[the-bloody-sadist]

Oooooo, could you do Yosano, Dazai, Kenji, Kyoka, and Atsushi?

Ps im ngl i always spell "actually" wrong 😣 i type so fast my autocorrect just cant keep up

CRACKS KNUCKLES OBNOXIOUSLY

(p.s. TYPE SLOWER. no jk that's actually so cute patpat it's okay little guy)

disclaimer first: a few of these characters I know very little about past what the anime offered and what my attention span was during their screen time, so forgive me if some of this trauma tie-in happens to be an element that already exists in some fashion (but isn't focused on) that I just didn't catch. Most of the ability stuff is just so fucking confusing and weird that I got used to dismissing any deeper looks into the possible meanings to their characters. REGARDLESS! I'm going to act as if I'm the co-writer of BSD and I have a skeleton of what their abilities/characters are supposed to be like.

other side note, I would make it the world rule of BSD that abilities are born out of either trauma or desperation, not inherent at birth. Each character has a past that involves how their ability was born.

Yosano

Ability birth:

I'd change her past to be that she was Mori's "favorite" (yes, in the inappropriate way) from wherever he met her, and he took her along to the war for company along with the other ability users, hoping to traumatize her enough to create some sort of ability birth in her. I'd make Mori, as a villain, someone who does this to children as a job, basically, unethically creating the birth of abilities by giving them trauma. Every mafia member is either an existing ability haver that he's hired to help him or a child he raised and traumatized to become ability users.

While in the war, Yosano would be a sensitive child obviously who hates seeing the mass deaths, and this would be the trigger for her healing ability to be born, because whenever she sees someone dying, she goes mad trying to save them.

Trauma history:

So she has a fairly traumatic backstory already that I think - out of all the characters in BSD - was portrayed pretty well, comparative to the others. However, with her ability to heal, and the wartime past with Mori arc, I would keep her deeply affected by that past event to the point where she's not proud of being a healer, even though it was born because she wanted people to stop dying. Mori soured that when he abused her ability after it was born to the point that she never wanted to see people revive again just to keep fighting.

Character change:

I would change Yosano to be a morbid character obsessed with death (and give her a metal goth-inspired design) who is dedicated to the idea that death is important, inevitable, and should not be prevented. Death is the ultimate rest, and Yosano would see herself as a perversion of nature who would be hindering that process if she were to heal anyone. This worldview would be entirely based on her experience in the war and how she kept soldiers on the battlefield so long that they went mad and only wished for death to escape their hell.

Relationships:

I would give her a close bond with Dazai because of this, seeing as that would make for some interesting partnerships. I would have her be sensitive to suicidal people because it triggers those memories, and she'd be undecided about whether she'd encourage Dazai in his wish to end things or stop him because she's attached to him.

Arc:

Her emotional arc for change (from refusing to heal to embracing her healing abilities for certain exceptions) could involve some sort of innocent NPC character (say, a child) who has a terminal illness and does not want to die. This could change her mind and she would choose to heal them before the end so that they could live a full life, and then decide that she'd use her healing abilities from then on only when death was an uncontrollable circumstance and an unwanted end, and only to prevent it until the character got the death they preferred. IDK, SOMETHING LIKE THAT. JUST OFF THE TOP OF MY HEAD.

Dazai

Ability birth:

With Mori established as the prime abuser/villain, Dazai would've been born a normal but sheltered boy, neglected by his parents (leading into the sensitivity of being "invisible" or "not human") who comes across Mori somehow and is lured to run away from home (because grooming, and the fact that he receives attention from Mori and thus believes it's "love", becoming convinced his parents don't love him). Then thrust into the mafia, Mori routinely abuses him to get him to form an ability. The focus on his abuse would be sexual and medical. Mori would be curious to see what would form out of someone with the fear of being invisible being told that they're inhuman and alone. He would isolate Dazai and leave him in dark rooms for hours if he showed emotion, and force him to murder and maim other people (or children) to make him as antisocial as possible. This would create the self-eating void of No Longer Human. It would be both a manifestation of Dazai's loss of self-worth as well as a shield against Mori's use of abilities on him to hurt him.

Character change:

NYEHEHEHEHEHEHE MY FAVORITE! Although I usually write Dazai in my fanfics with these elements, just realistic-ized instead of supernatural-based, here's what I'd do for him in the canon, disregarding all fanon portrayals of him as this sort of character, already: No Longer Human is, by nature, an ability that destroys and makes the abnormal "normal". Dazai would be the ultimate contradiction to the "normal", being a human devoid of emotional expression entirely, himself a void to give only other people normality. Basing him more heavily off of his ability's namesake book (and the protagonist, Yozo), Dazai would be in a constant state of severe depression to the point of antisocial behaviors and sociopathic inclinations. Any attempts to help him escape this would be impossible, as his ability is so inherently parasitical that Dazai is subhuman, only able to "cure" others (by robbing them of their abilities while he is in contact with them). I would focus on him as a moral grey, the unpredictable character in the show who'd be more likely to join the villains at a moments notice and forsake our protagonist.

Trauma history:

His trauma history, other than Mori - namely, Odasaku's death - would be a major part of his character. Because of Oda, who was his first and only companion that didn't care about how strange and inhuman he was, died at what he sees to be his own failures, Dazai would think of himself as incapable of human connection without the threat of annihilating either the humanity of the other person or the literal life of the other person. To try and be more simple (sorry I'm so wordy, I hope it's not confusing), I'd say he'd be paranoid of falling into the "trap" of human connection now (thus leading to the antisocial behavior) and would attempt to push people away because he's convinced the past would repeat itself. "Anything worth having will be lost" and all that.

Current behaviors (in relation to the trauma):

Mr. touch-starved, touch-averse. Since his ability is based on contact, I'd make a Dazai who wears bandages not only to cover the egregious self-harm, but to cover up as much skin as possible, because he's convinced it will help him not touch people. I'd add a dash of reverse-mysophobia in there (mysophobia is the extreme phobia of germs) to add to how he feels as though he contaminates anyone he touches because of NLH. Since I'd keep Oda's last wish in his trauma history, Dazai would be in the ADA, but the complete detachment of his coworkers from emotionally caring for him would make Dazai a machine driven by the necessity to carry out Oda's last wish - to use his ability for good. Since he doesn't want to think about his time with Mori or be alone (even though he believes he deserves to be alone), he is staying with the agency out of duty and escapism from himself. His single use is to be a weapon to stop villains from abusing their powers. God, I'm so sorry, I have WAY too many thoughts about how I'd use this for Dazai, I hope it isn't coming out like the jumbled mess I think it is. Anyway, I'd also make him asexual, monotone-voiced, and brooding. He'd be a walking representation of how sexual trauma in particular can affect someone, making them feel worthless.

Relationships:

As mentioned with my version of Yosano, I think I'd pair them as acquaintances who work well together. Dazai likes anyone who thinks he should die, and his suicide attempts would remain a part of his character as well, just treated with actual weight. He interprets Yosano's love of death as a wish for him to kill himself, so when he has the time, he tries his best, but is notoriously bad at going all the way through. I'd give him one thing hindering him: the insatiable wish to not be lonely before he dies. The wish to find one friend to relive his Oda trauma, except this time with him dying happy instead of the other person, thus leaving them to live their life in peace without his burden.

Arc:

The chance to have his wish fulfilled would come in the form of Atsushi. Atsushi being oblivious, socially unaware, and unbothered by how strange Dazai is - as well as genuinely caring about his wellbeing - would trigger those old feelings about Oda, forcing Dazai to unconsciously seek out a repetition of his trauma. This time, however, he'd succeed. Atsushi would become close to him, and Dazai would protect him, and once it got to the part where he's ready to kill himself to relieve Atsushi of the burden of his existence, Atsushi would stop him and make it known how little of a burden he is, and how much good Atsushi sees in him.

Kenji

Character change:

OKAY THIS ONE IS ACTUALLY HARD. Kenji is such a bright character, and for the sake of contrast if I were to rewrite BSD, I would keep him that way, because a story filled with characters who are all as bleak and depressed as each other makes for a boring portrayal of trauma. Because, if everyone has trauma, NOBODY has trauma. Syndrome reference. They all cancel each other out and become far less important. HOWEVER. In a void, if I were to keep Kenji in line with my ability = trauma, I would give him the archetype of "the smiling goofball with the most crushing backstory who somehow made it through and came out the other side without mental illnesses and a love for humanity" if that....isn't too wordy. Does that make sense? Like Vash the Stampede in Trigun Stampede, basically. You'd have no idea this guy suffered until he told you his backstory while grinning ear to ear in the special side episode that you thought was going to be filler. He'd have the "yeah it was rough but I don't mind! I'm just sad for the other people who got hurt!" type beat and there would be 300 fanfics made about him breaking down because the fandom never got to see him cry in canon.

Ability birth/trauma history:

Kenji's superhuman strength would be born out of the landslides incident in his village. I wouldn't make it too deep, really, just your usual natural disaster trauma. I don't remember anything about Kenji's family if they were mentioned in BSD, but let's just say he lived with his family in the village very happily until the landslide incident. One of his family members got crushed under a falling tree (not dead, just trapped and injured), and Kenji's ability manifested out of the desperation to save them because nobody else could. Family member survived but was left disabled for the rest of their life. Kenji would be triggered in current day if he were to see anyone in life-threatening situations, but he would have the fight response and would be confident in his ability to save them.

Arc:

No arc for him, he's emotionally stable and would be there to assist other characters in their arcs!

Kyouka

I love Kyouka's current character type, so I wouldn't change anything about how she's written in the main storyline, BUT SHE DOES HAVE A WELL OF TRAUMA TO DRAW FROM! This is what I'd do with that:

Ability birth:

First of all, Kyouka's backstory is a bit weird to understand in relation to her ability itself, so I would simplify and change a few details, even though I do like some of the elements of its portrayal in the anime. Second of all, I love the Kouyou (I'm trying hard to spell everyone's names right) mother-daughter relationship going on with her, so I'd first of all have to build up my version of Kouyou.

Kouyou in canon wanted to leave the mafia with a man she admired, so let me harp on that by saying her motivation was that she wanted to have a family with him. Classic. Okay, so she fails in that in canon, the man gets killed, and she holds a grudge against the head of the mafia at that time (not Mori). Once the mafia is taken over by Mori, she was involved with the killing of the former mafia leader, so she becomes enthralled by Mori's sick passion and attached to the children he brings in. This is her own perverse version of a family, the only kind she'll get. She forgives herself for being Mori's enabler by convincing herself that she's the refuge for all the hurting children he brings into the mafia. She is their mother figure. To Chuuya, to Dazai, to Kouyou, etc.

Okay, NOW enter Kyouka, the new target of Mori's current attempt to make yet another ability user. Kouyou wants a little girl to take care of (she hates Elise, we all hate Elise), tired of all the boys. Mori preys on this and uses that motivation to convince Kouyou to kill Kyouka's mother and take the mother's place. This will bond her to the child.

Kouyou is all for this. Kouyou would become Kyouka's mother's assassin.

Once in the mafia, Kyouka is not like the others because she's basically a kidnapping victim instead of a grooming victim lured into the mafia. Stockholm syndrome manifests while Kouyou spoils Kyouka, but Mori is ofc determined to traumatize her. However, they underestimate how much smarter Kyouka is than some of the other children, and she is aware that Kouyou is only being kind to her to try and replace her mother. Her ability manifests as a way to preserve her mother's memory. Her ability would BE a ghost of her mother, basically, here to protect Kyouka from the fakers.

LONG WAY TO SAY THAT BUT HEY, KYOUKA HAD A GOOD BASELINE TO DRAW FROM. I would also tie in the phone by putting that into the trauma of her mother's death. During the assassination, Kyouka was on the phone with her mother, coming home from school. Since her mother was attacked while she was apart from her and she heard her mother's death on the phone, her trauma links directly to that, and Demon Snow would have a consistent phone-voice if it were to speak to represent those last moments of her life.

Current behavior (in relation to the trauma):

In joining the ADA and that whole thing, the one trigger I'd focus on would be that Kyouka refuses to talk on the phone with anybody. Everyone who works with her has to work around this, because she's internally convinced that talking on the phone will 1) cause someone to be compelled by her words (since Demon Snow follows phone commands) and 2) make her afraid that person will somehow meet misfortune if they speak over the phone. She'd retain that superstition.

Arc/relationships:

I would make an episode where Kyouka has to overcome her fear of talking on the phone. She'd still be close with Atsushi mainly but I would probably add a dash of Yosano in there as well, helping Kyouka process death as a whole and especially in relation to her mother. I would present a main conflict where Kyouka could put others in danger if she doesn't use a phone (say, a 911 call), and no other character is there to do it for her. She sees how her superstition doesn't come to pass because the 911 call brings only help and solves the situation, and then could grow when she realizes that she's allowed to be angry for her mother's death, and allowed to keep Demon Snow in honor of her memory, helping instead of harming others. She is also allowed to protect herself from harm. Basically Demon Snow would represent the grieving process in some way.

Atsushi

I really hate this guy in canon, I do apologize for how much I'm going to change him.

Character change:

To start, I'm a huge hater of canon Atsushi (as mentioned), but quite a fan of BEAST Atsushi, in comparison. I would rebuild his character based more on BEAST than BSD. Okay, so it's widely tossed around that Atsushi is a good representation of PTSD (he's not, from an officially diagnosed CPTSD haver, I'm sorry, though if anyone who has PTSD likes his representation, I'm happy for you <3 live in peace). I would shift him to be a representation for survivor's guilt. Why this choice? First of all, my changes would already make almost every character a representation of PTSD because all abilities would be a metaphor for PTSD. I'll get into the changes for his backstory to fit this narrative in a second. But I want to merge his BSD and BEAST personalities together. In BSD, he's always making everything his fault somehow and using self-blame like it's a personality quirk. I want to use this, and mesh it with the more serious personality he has in BEAST. He'd remain an ADA member, but he'd be less... comedically brainless. First of all, autism. Yay!!! I love socially awkward characters if they're not overdone, so I would give Atsushi the "not labelled but definitely autistic" character type. Social cues are hard, he struggles to make genuine connections or "correctly" convey his emotions, all that. This would make him a better match-up for Dazai since they would find some common ground in the emotions department, with Dazai being keen on understanding the way others act socially but not WISHING to participate, and Atsushi just not knowing how to participate "properly". He would feel bad about this as a main character conflict, wishing to assimilate into "normal" society better when he feels so alienated. This would also fit his um....unique? eccentric? Character design and haircut. JUST SAYING. The arc (which I'll talk about in a second) would be about accepting himself the way he is instead of forcing himself to assimilate to society, so don't think I'm making him autistic as some sort of derogatory thing. Not at all.

Trauma history:

So I mentioned I would give him the survivors guilt theme. For his orphanage backstory, I would build up the fact that he was "the weird kid" but he really loved the children he was around and desired to connect with them. The abusive caretakers I would tone down a bit to give some more realism to the abuse, because I find the backstory ridiculous and tacky in canon. I'd take inspiration from real life horror houses and camp counselor stories, especially the psychological manipulation of making kids tattletales on each other, essentially, as a way to protect themselves. If anyone does anything "wrong", the kids can earn themselves a day of rest from the abuse by being the caretaker's "pet" and telling them who transgressed. I'd keep the elements of Atsushi being put in solitary confinement situations (but not chained up), starvation, physical abuse and threats to permanently maim any children that ran away (crushing their legs/ankles etc.).

Because of this, Atsushi's personality would form around the desire to be the savior of all the other children. Tokyo Ghoul ahh sentiments like "it's better to be hurt than to hurt others" would be his motto. Self-sacrificing little guy. He would get himself in trouble just to redirect attention from other, more fragile kids, and thus become the main target of the abusers. However, as what usually happens in reality with hero-minded people in groups like this, the abusers would convince the kids that this was because Atsushi thought he was better than them, so the kids would alienate him since it gets them rewards from their abusers and relief from abuse. If Atsushi wants to take the fall for them, by all means, let him take the fall. Atsushi gets blamed for everything. (This is how it can make his current self-blame behavior make more sense)

Ability birth:

Atsushi's Beast Beneath the Moonlight would birth under the extreme stress of being everyone's punching bag. Atsushi, like any victim of abuse, would be bothered at first by the reaction of anger and hatred he has in his heart when kids blame him and when abusers go after him again and again. Even though a lot of this hatred is self-focused, there's a growing rage against the monsters hurting him, and a need to become a monster to hurt them back. Also, the need to fulfill their accusations that he is the monster. AKA "fine, I'll be the villain you want me to be" arc. Atsushi is abused until he hits a breaking point, finally, and can't take it anymore. He accepts that instead of being hurt constantly, he does want to hurt his abusers back, he does want to kill them, and the Beast is born, a trauma holder that is out of his control. On the day of its birth, it destroys the entire orphanage in a blind rage, and Atsushi blanks out during the attack. The main drive of his current story would be him trying to figure out what actually happened that day after waking up where he does in BSD's first scene.

Current behavior, relationships, & arc:

Since Atsushi would theoretically be the main character, still, his ability would stand as more unique since he has zero control of it. This would be because he refuses to process his trauma in the orphanage, only retaining the survivor's guilt about "a disaster happened and I was the only survivor, but I don't know what the disaster was caused by, only that I blame myself". I would have Fukuzawa, Kyouka, and Dazai be the main accomplices to solving this for him as well as emotionally assisting in his arc to accepting what he did and understanding the nature of his beast. It would be a nice way to explore the rage that survivors of childhood abuse retain for their abusers, and how dangerous it can be if you don't process that trauma in a healthy way. The whole goal would be to keep Atsushi from denying that his childhood abuse hurt him and that it was fucked up. The other characters would be motivated to do this because of the disaster that would come of Atsushi losing himself to his beast and going on a rampage.

This is probably why Atsushi in canon makes me so annoyed, by the way, because he had such POTENTIAL with the metaphors to really represent PTSD and trauma, but failed miserably and instead just repeated a single scene on a loop until I wanted to blow my brains out. "it would've been better if you'd just died in a ditch somewhere" is my winter soldier trigger phrase now.

....

OH MY GOD I'M DONNEEEEEE, THANK YOU FOR GIVING ME THE CHANCE TO RAMBLE MY ASS OFF!!! Clearly I love the chance to do it, so if you want to give me any other characters (if I didn't make you regret asking), PLEASE FEEL FREE! I would love to see what rolls out of my head with the right prompts! I spend so much time focusing on Dazai that I've forgotten about how much unused potential lies in the other cast.

THANK YOU AGAIN, I HOPE ANYONE WHO READS THIS FINDS THEMSELVES ENTERTAINED! And if it happens to be of any quality, you have my full permission to use this shit for your own fanfics if you'd like, just credit me if you please! I'd never spend enough time on characters aside from Dazai to actually use these ideas, so I'd be thrilled to see what others come up with. Please oh please write me an AU so I don't have to, I want to indulge....
