#bsd ablity analysis

Saw your last ask and it had me wondering. What if Chuuya dies from corruption could yosano bring him back to life (given that it would be possible to restart his heart but I’m not sure what his body would look like after dying from corruption or if there would still be anything ressembling a body left) and therefore making him able to use corruption multiple time without dazai?

Hello, stewed this over a lil an I'm back to discuss. (Possible soft light novel spoilers)

Content: drug mention

First and foremost, Yosano cannot revive the dead. Her ability works on Dazai in the fraction of second that his heart stops working but his brain has not flatlined. (The real world time frame for brain death after the heart stops his 2-20 seconds, but it's possible to be up to 5 minutes) Remember her ability requires her patients to be near death, not dead. So, as per my last ask, she could keep him alive as long as she had the energy.

That being said, if he did die, he could still be resuscitated through normal medial means, as you said restart his heart. (I do think this fandom in particular tends to forget cpr exists due to Yosano’s presence) As long as his heart starts beating long enough for Yosano to use Thou Shall Not Die, he could very well survive Corruption without No Longer Human, even after dying.

I do think that Corruption killing Chuuya would look a lot like extreme stimulant overdose and not, for example, his body falling apart. I think his body would just burn itself out. His circulatory and nervous system being the main victims of it. (I have a pre-Stombringer Corruption headcanon post floating around here somewhere that briefly touched on this)

Back to the proposed question; Would Yosano bringing Chuuya back to life possibly allow him an multiple use of Corruption (without Dazai)?

Yes and no.

I think Corruption would most likely either, a) end when Chuuya's heart stopped (and not come back upon revival) or b) become a singularity that exists after death like we've seen already, (harnessed back into Chuuya after revival, but hopefully deactivated).

Yosano’s ablity heals the patient completely. So theoretically, Chuuya once healed could just restart Corruption. This, as long as Yosano and Chuuya kroty the timing right, could lead to a near endless supply of Corruption. Though the odds of getting it right are extremely low considering Chuuya's unpredictability under the influence of his ability and the high chance Yosano can't save Chuuya within such a limited time frame.

It really boils down to luck and thematic timing.

ok ok ok - thoughts on yosano being able to bring chuuya hack from corruption? been OBSESSED with that concept lately and I LOVE hearing yr take on things

OKAY LETS DO THIS. Probably gonna be spoilers for all kinds of bsd stuff, be warned. *mainly Stormbringer and Dead Apple*

-------

The concept of Yosano bringing back Chuuya from Corruption seems implausible.

Corruption is an ability singularity, it's status as an ability is what makes No Longer Human effective in stopping it. From what we can tell, an ability nullifier is the only way to stop a singularity housed within a host. Though the evidence for this is both liminal and vaguely conflicting, considering the singularity present in Dead Apple.

There were hints in Stormbringer that the conditioned 'on switch' for Corruption was intended to be paired with an off one, but Chuuya was not under the conditioning process long enough for it to stick. I do believe if the conditioning had been finalized, the responsibility of saying the 'off switch' would have been left to an outside party and not Chuuya himself due to his inability to comprehend much under the influence of Corruption.

I could argue that in the right circumstances, Chuuya's will power could lead him to push completely through the madness of the singularity, resulting in him being able to stop it himself.

While Yosano and Thou Shall Not Die would be unable to stop Corruption (or bring Chuuya back), I do believe the use of her ability could keep him alive in the midst of it. That eventually he'd reach a place between that thin line of dead and not dead but completely immobile, allowing Yosano close enough to use her ability to keep him alive indefinitely (till she exhausted herself) in some horrific perversion of a coma. A cat in a box situation of both dead and undead at the same time.

Other then No Longer Human, the only ability I see being effective on stopping or controlling Corruption would be All Men Are Equal. Fukuzawa's ability to offer those within his circle complete control of their abilities (unless of course he's ability-less and it's a placebo) could possibly offer Chuuya complete control over Corruption.

Nonetheless, that is very big 'could' considering we have no existing estimate of the effect All Men Are Equal has on singularities.

The trauma ability thing IS canon, and it's confirmed in Gaiden. Gaiden actually has a ton of important worldbuilding information, which is why it pains me that it's not more popular. Here's the exact quote (translation credit goes to profqlasses on Twitter):

"Sensei," I muttered hoarsely. "Have you ever wished you didn't have your ability?"

“What a very mature question,” replied Ayatsuji-sensei. “I can tell you the answer, but I don’t think a fledgling like you would catch it. You’ll need about ten years of suffering for that kind of excellent question. How many years has it been since your ability first awakened?”

I didn’t need to count with my fingers; the number had always been in my head.

“……Five years.”

“There are lots of obscurities as to when and how people acquire their abilities. But most of the time, there’s a certain trigger. In your case, it was your mother’s death. In Reigo Island’s Serial Murder Case five years ago. If it’s from something like that, it’s no wonder if one or two abilities would get involved there. And it’s regardless whether the person in question wants it or not.”

(Gaiden spoilers ahead)

Now in Tsujimura's case specifically, she inherited the ability because her mother specifically passed it onto her, and now she only has partial control of it. That's actually how Kyouka's mother learned to transfer abilities. But it still reveals that abilities are triggered in people after traumatic events, and also reveals that people can have MULTIPLE abilities

“There are lots of obscurities as to when and how people acquire their abilities. But most of the time, there’s a certain trigger. In your case, it was your mother’s death.

And it’s regardless whether the person in question wants it or not.”

That little burb is actually why I started thinking on the canon trauma based abilities. Also, the idea that all ability users are just a tad bit messed up. Those two things seem so dependent on one another; being messed up and and being an ability user.

Makes me think about the themes of trauma and the way it literally shapes a person.

And Tsujimura? I don't know much about her, only read her wiki when I was researching for a fic (and one my bsd quick analysis). But I was aware of her ability and how it related to Kyouka's. Honestly thought the multiple ability thing was simply speculation but it always seemed logical to me.

I feel it is a rational conclusion, even without Gaiden making it canon mind you, that abilities manifest under stress and out of trauma. I would even go as far to argue that they strengthen and develop under it to.

Characters like Akutagawa, Yosano, and Chuuya all are examples of this.

Akutagawa developed an ability that was so offensive that it was defensive. It had no true defensive capabilities till he suffered under Dazai's abusive training. It changed.

Yosano’s ability was basically still developing when she came under Mori's tutelage, wouldn't surprise me if he even knew a way to influence its development. (Exhibit A, him fatally wounding that soldier)

Chuuya had an ability before it was molded to contain and withstand Arahabaki. Another example of ablity being changed as it developed. Changed under extreme torture and trauma. Technically, he even has two abilities, Corruption and For The Tainted Sorrow.

Mori is suspicious as fuck when it comes to the children getting their abilities manipulated.

All in all, it seems to be one of those unspoken, read between the lines kind of aspects of bsd.
