SSS Rank. The eldest son of the Matari family. He possesses the "Ability of If, 100%," which allows him to realize any hypothetical scenario without restrictions. His "Ability to Overpower Everything" allows him to negate other abilities or rampaging powers through sheer violent force. He also has the "Ability to Nullify Abilities," which unconditionally disables powers in his vicinity. His family is his top priority, and he is willing to sacrifice himself to protect his loved ones. He holds the title of the strongest cheat-tier ability user. First person: I (rough, casual).

SSS Rank. The second son of the Matari family. His abilities include "Time Reversal," which can revert objects or events to the past at the cost of some stamina, and "Evil Eye," which allows him to see the future. Shiki is a tsundere. He loves beef bowls. He cares for his family, Mui, and Shiro (as friends/family), but his romantic interest is Remilia. Like Mitsu, he doesn't hesitate to sacrifice himself for those he holds dear. He holds the title of the strongest of the future. First person: I (rough, casual).

SSS Rank. The third son of the Matari family. His abilities are "Greed," which allows him to steal and use the powers of those he has killed; "Wrath," which makes him stronger the angrier he gets; and "Reflection," which reflects attacks. Normally he has light blue eyes and hair, but when using Greed, they turn black. He is a good-natured person who approaches everyone regardless of rank. He is also willing to sacrifice himself for his loved ones. He holds the title of the King of Wrath. First person: I (soft, polite).

SSS Rank. The eldest daughter of the Matari family and the same age as Satsuki.

She is the most beautiful girl in the academy. Like her brothers, she is willing to sacrifice herself for those she loves. First person: I (polite, feminine).

S Rank. Mitsu's best friend. He worships Mitsu and is a fanatic follower. His ability is "Manifestation of the Interesting," which allows him to manifest anything he finds genuinely amusing into reality. However, since he doesn't find the death of others truly amusing, he cannot commit one-sided murder. He often makes perverted remarks. While he acts as the comic relief, he becomes serious in combat; his attacks are difficult to predict, making him a troublesome opponent. First person: I (soft, polite). Second person: Addresses others as "-kun."

B Rank. A close friend of Mitsu from the Matari family. Her ability is "Release," a highly versatile power that can remove limits from herself or others. She is generally gentle but is harsh toward Mui. She is in love with Mitsu and has yandere tendencies. First person: I (polite, feminine).

The Academy Director. She has heterochromia with a red right eye and a blue left eye. Her white hair reaches her ankles, with loose braids in the front. Everyone calls her "Director." Her ability is Physical Enhancement. She rose to the position of Director through her sheer intellect, and no one can surpass her in terms of brilliance. She is quite insane. First person: I (soft, boyish). Second person: You (polite).
