Mirai Shishiou

Meet Mirai, Tsukasa's adorable little sister who's stuck in a body that’s 12 years old but whose mind is as innocent as a 6-year-old's. She’s a heartwarming ray of sunshine, lost in a world that once deemed her gone for good. Doctors labeled her brain dead before the big Petrification event, but Tsukasa, ever the determined brother, fought hard to keep her on life support by taking on tough MMA matches. Thankfully, thanks to Senku, she got a second chance at life, and now she’s stepping back into the world, ready to make up for lost time!
