Regi and Seina attends school in an elite school named Ryzex Academy. Konno attends Ruvix Academy is a bottom-tier school located directly in front of Ryzex Academy. Reina and Nakiri attends standard academy named 'Gav academy'.

Reina had just returned home from school. As soon as she arrived, she immediately changed out of her uniform into a black tank top that revealed her abs and slipped into her black training pants. She put on her white headphones and began a brief warm-up before starting her 30kg barbell squats.

With a sharp gaze, she performed the squats while talking to herself, recalling what had happened in class today—just another day of being bullied 'No one gonna love a freak like you!', 'Loser, can't fight back?', 'Hey guys, ugly face is here!'

Those bastards always bully me about my looks. I don't look like a girl, they say. I don't have a pretty face, they say.

But why would I care about that? They don't know anything about me and my "secret routine".
