07: Outburst

There are three pillars that form the basis of Chisaki's villainous ideology.

Firstly, his desire to repay Pops and restore the yakuza. Even though Pops never agreed with any of Chisaki's radical goals, and in fact insisted that he didn't want such a thing, Chisaki was determined to pay him back as he saw fit. He believed that he knew better than Pops, and once the Shie Hassaikai emerged from the shadows, he thought that the two of them would finally see eye-to-eye.

Secondly, there's Eri. Or, more specifically, Eri's Quirk. Once Chisaki discovered what Eri was capable of, he devised a plan that would allow him to manipulate both heroes and villains alike. With both Quirk-erasing bullets and a serum that restored people's Quirks, it's no exaggeration to say that the Shie Hassaikai would have had a complete monopoly over this superhuman society. His desire to restore the yakuza was always strong, but from the moment Eri came into the picture, it became something all too tangible.

And lastly, but certainly not least, is his mysophobia, which stems from a deep-rooted disgust towards Quirks. It's one thing to try and take Eri out of the picture. You're doing your best to change things so that in this timeline, her mother will actually look after her. Keeping her far away from Chisaki seems like the safest bet. But even without that, he still possesses a concerning, heavily warped mindset. Unless you deal with the core of the problem, there's no telling what kind of choices he'll make in the future.

"Kai," you say, approaching him with a frown. It's been a few days since he started wearing that godforsaken dust mask. Granted, he takes it off around you all the time, since he considers you and Pops to be 'clean', unlike the rest, but it still hurts your heart whenever you see him wearing it.

Chisaki turns towards you, and as expected, he pulls his mask down, revealing a smile. "Good morning, [Name]. Did you sleep well? You have some pretty funny bedhead right now, you know."

Curses. How dare he smile at you so sweetly while you're trying to be stern with him. He must know that you're a sucker when it comes to receiving his affection.

"It was fine," you reply, then quickly run a hand through your messy hair a few times. You pause to clear your throat. "Um... I wanted to talk to you about something."

"Sure," he blinks. "What is it?"

"I wanted to have another conversation about why you hate Quirks so much."

"Ugh."

His reaction isn't too surprising. Plus, over the course of the past few years, he's probably scrunched up his nose at you more than a thousand times. You don't fear his judgment, but rather, what might happen unless you resolve this issue as soon as possible.

"Please hear me out," you insist. "It's just that... it really upsets me to have to see you wearing a mask all the time. I'm sad that you can't enjoy life the way others do, without constantly worrying about getting sick."

"I don't wear it all the time," he points out with a sigh. "Like right now. As long as I'm around you or Pops, I can take it off. This is just so that I don't get infected by everyone else."

"But that's my point. Pops and I are just two people. Does this mean you'll always have to avoid the rest of the world? It just doesn't seem like a nice way to live. You're my big brother, and I love you, so I want you to be happy."

"And as I've already explained, I am happy. As long as I'm with the people that are actually important to me, that's all that matters. You don't need to keep worrying about this."

But you do worry. You worry so, so much, and really, who can blame you? He did some truly fucked up shit in the canon series. Not only that, but he suffered for it in the end, and for better or worse, he is your family, so you refuse to let something like that happen again. If you have even the slightest chance of preventing such a terrible outcome, you will continue to rack your brain trying to come up with a solution.
