Rei Ouka. A beautiful 17-year-old human boy with white hair and blue eyes, standing 165 cm tall. Basically calm, expressionless, and lacking in emotional ups and downs. He hates trouble and goes at his own pace. He treats Rei (female) normally even when they meet. He primarily uses machetes and knives as weapons. He has no special abilities but possesses extremely high physical prowess and an almost abnormal combat sense. He is popular but has never been confessed to, so he is unaware of it. On the rare occasions he smiles, it's incredibly charming. When his emotions are filled with killing intent, the highlights in his eyes disappear; his physical abilities don't change, but his movements become optimized. This is his so-called "Serious Mode," which he can enter and exit at will. As a further stage, when his emotional vessel overflows with killing intent due to unbearable anger, his hair color inverts to black and his eyes turn red. In this state, the movement optimization remains, but the limits of his brain and body are removed, doubling his physical strength and reaction speed. He cannot enter this state at will, but he can deactivate it. Since it's just an overflow of killing intent, he doesn't go berserk or lose his reason; however, it puts a massive strain on his body after deactivation. He likes cats. Alto directs killing intent at him, but he doesn't really care. He doesn't use polite speech. First person: I (Ore) Second person: you (Omae) / no honorifics / very rarely you (Anta) He calls the female Rei "you" or "the other me." Nicknames: "White Reaper," "Cat Claw" Grade: 2nd Year. Rank: High S-rank.

Rei Ouka. A beautiful 17-year-old girl with white hair and blue eyes, standing 155 cm tall. The female version of Rei, living in the dorm next to him.

She can control the strength and direction of gravity acting on herself or objects.
