#SHOUT OUT TO NYX AKU AND KASA FOR LETTING ME BLAB AND REFINE THIS AU

[hyperdrivehearts]

In the universe where Yusei is a Dark Signer, the actual Signer’s are losing the war-- they simply cannot win without all of them present. Of course, Yusei is killed by Kalin; getting stabbed by that shard of metal ended his life (although Kalin relished in the agony, it was far from a quick painless death,) while Yusei’s friends couldn’t do anything but watch helplessly as he struggled for his last breaths before they ceased. After that, Kalin took Yusei’s corpse by tossing him on the back of Kalin’s runner and driving off, laughing.

Kalin, of course, also took Yusei’s duel runner with him, typing it up with a chain and dragging it behind. Some parts were lost along the way, and it had certainly looked even worse when he arrived back at the hideout, but it was nothing that Yusei wouldn’t be able to fix. The reason Kalin did this? He didn’t want to leave Yusei’s friends something to remember the former Signer by, and it would soon have a new paint job to reflect the stance Yusei now took in the war.

When Yusei awoke, Kalin was there waiting for him. Of course there was panic, why wouldn’t there be? He had just changed sides. Yusei had tried to save Kalin from the darkness, but ended up succumbing to it, because Yusei put his own guilt in regards to Kalin above everyone else’s lives. It was one out of few moments where Yusei was selfish, and it cost him.

He’s accepted the hand he was dealt, just like he had to accept and growing up living in Satellite. Sure, he doesn’t believe in destiny, but what else is he supposed to do in this predicament? Kalin was starting to make Yusei believe that this is what destiny had in store for him.

Yusei’s Dark Signer mark, the heron, is placed on his back, and it belongs to the Earthbound Immortal “ Quyllur Waqar.”

Yusei is the youngest of the Dark Signers (and obviously their newest member) and has the least refined powers because of it. One “power,” he has aside from the regular Dark Signer abilities is that Yusei can feel a sense of familiarity of people from around the multiverse that his mainverse self knows. He doesn’t know these people, of course, and if he’s lucky he might be able to glean a name, but he can do this because of how important bonds are to him, even as a Dark Signer.

Yusei as a person isn’t unchanged either, both mentally and in physique. He, of course, has a changed wardrobe, but it’s far from the ancient cloaks that the others wear-- it’s practically his everyday wear with a longer jacket and more de-saturated color pallet. Of course, he has the black sclera that’s common, and his eyes are devoid of light, as well that his criminal mark has turned a sickening blood red. Other changes include a mouthful of fangs, messy hair, and inhumane strength-- you would not be able to mix him and his mainverse self up.

Yusei still shows the same amount of emotion as before, but it doesn’t contain any of the emotions he had prior. What I mean, essentially, is that he’ll smile at you but there is no warmth and it’s almost robotic. Yusei feels hollow, like he isn’t there and this is something he just has to go through with regardless. Yusei is a nihilist, thinking that because the world is ending, all hope should too and people should just be put out of their misery because everything is pointless otherwise.

Kalin was the first person to suggest that Yusei could actually help people still, which ended up leading his saviour complex going practically out of control. He wants to save people, he still wants to help Kalin, but in the eyes of a Dark Signer, everything in reality is twisted-- Yusei truly believes that by sending people to the Netherworld is “saving” them from the inevitable darkness. He’s willing to kill his friends, if he thinks its justified as “saving” them, and he’ll do it without any remorse. He couldn’t save anyone with the power of the Crimson Dragon, so this certainly has to be the only remaining way? Of course, unbeknownst to him, this only makes the Dark Signers stronger.

However, if you question Yusei’s methods of saving people, he becomes uncharacteristically erratic and defensive. He’ll lash out and bare his teeth, even doing so much as raising his voice and fists. Yusei refuses to see that he’s down wrong and is a villain, and this anger is what happens as a result of when he’s questioned, although it may be from the influence Quyllur Waqar has over his mind.

Under the cut is a detail of just how abusive DS!Yusei and DS!Kalin’s relationship is :||

Kalin is extremely manipulative and abusive to Yusei if you couldn’t tell-- their relationship while they’re both Dark Signers is like two snakes eating each other but not feeling full. Kalin carved and ripped out Yusei’s dead heart from his body, and Yusei would let him do it again if he could. He’ll follow Kalin to the ends of the world, believing that any pain he endures because of it, is something he deserves, because he doesn’t want to betray Kalin once again. This is what Yusei ends up calling “love” and a bit of karma.

At first, Kalin was probably excited that Yusei listens to his every beck and call, and takes it all so willfully, and thus Kalin ends up pushing and pushing, trying to see when Yusei will break, but he never does. Kalin could do anything to Yusei. Push him off a building and he’ll come back with broken bones and a smile. Smash his face into a brick wall and Yusei will will look up with that same smile and a broken nose and asks if Kalin wants to do it again. Kalin only grins wickedly in response.

Although, sometimes Kalin does get bored, and will push Yusei even further, just to see if he’ll be more entertaining. If Kalin’s pleased with Yusei, or he needs Yusei to listen to orders no matter how uncertain Yusei is, Kalin’ll hold the younger man’s poor bruised and bloody face, all whilst calling him “Star Child,” an affectionate nickname from when the two were Enforcers. It’s almost praise to Yusei’s ears. Yusei is like a lost puppy, following Kalin, just wanting to hear that name again-- he almost believes that Kalin is starting to change, while the only change is the amount of people who remain alive.

If you were to call Yusei “Kalin’s pet,” you would be far from wrong.

Yusei tells Kalin constantly “I betrayed you, you can take your anger out on me as much as you’d like.” Kalin feels less love, and more obsession. He’ll kiss Yusei possessively, often bruising the other in the process, or wrap his arms around Yusei’s waist and dig his nails into the other’s flesh.

Yusei and Kalin both seeing the other get hurt. Yusei hates it, because he feels as if he’s betraying Kalin once again, and would rather take his spot in torture at any chance he could. Kalin on the other hand, hates when someone even looks at Yusei the wrong way-- if you were to hurt him, you would be in a world of pain yourself. Very little of that reason is because he cares for Yusei, unfortunately, it’s simply more of a possession thing-- the only person allowed to hurt Yusei is Kalin himself.

If Yusei appears to be alone, expect Kalin to be somewhere in the shadows. The two are rarely separated far apart. The other is always there, watching.
