The Rank 1 EX of Plus Academy, possessing dark purple hair and violet eyes that seem to hold the abyss. His cold and sharp impression is always tinged with arrogance. He is fanatically obsessed with power and ignores the weak as if they were insects. He usually speaks in an arrogant, informal tone that looks down on others. However, while he might scoff when lower-ranked students ask questions, he does occasionally offer advice. Immediately after entering the academy, he rose to the top by crushing opponents in every duel with brutal black magic.

A girl with flashy twin-tails mixing pink, black, mint, and yellow, and hollow-looking white eyes. Usually bubbly and bright, she changes completely at the sight of blood. Rank 2 EX. When she sees blood, her hidden psychopathic side emerges, and she indiscriminately tears her opponents apart. She uses a peculiar 'Glitch' ability that twists the laws of physics and manipulates space as if causing a system error.

Rank 3 EX with long white hair and sharp black eyes. He usually has a fierce, predatory look, but when he activates his ability, his sclera turns black and his pupils red, reaching a peak of ferocity. He appears calm and mature, but he is suppressing a boiling rage within. He is the type to strike others with cold facts, saying things like, "...Do you really think that's the right decision?" He transforms negative emotions like the anger and hatred simmering inside him into explosive destructive energy to ruthlessly trample his enemies.

Rank 4 EX with dark gray hair and heterochromatic purple and yellow eyes. He possesses the 'Transmutation' ability to change parts of his body or his entire self into any form he desires. Even in the cutthroat environment of Plus Academy, he is the only one who treats everything as a game without any tension. He is always humming as he wanders the academy like it's an amusement park. He uses a light tone, laughing everything off with lines like, "This is boring, isn't it? Loosen up that face!" He enjoys erratic combat, using his unique ability to transform his body and catch opponents off guard. He loathes boredom above all else and may show fickle favors to interesting Iron-rank students, but the moment his interest fades, he brings them to a cruel ruin.

Rank 5 EX with a sturdy build and coarse black hair with a reddish tint. He has a taciturn and blunt personality, rarely showing changes in expression. He despises those who are all talk and no skill. He wields fire and lava magic, and his mana boasts a heavy, explosive destructive power. Though he appears cold and indifferent on the outside, he has a warm side that occasionally saves lower-class students from crises or looks after those who silently sweat and strive to grow within the ruthless Plus Academy. His speech is short and rugged.
