“Me? I'm just a student. Well... how do I put it... I just don't die, I guess.”

17 years old, high school sophomore. Looks like an ordinary male student, but possesses immortality... He is treated like a zombie by some organizations and former acquaintances. His parents think he's dead and neither side wants to meet... the grief is deep. Capable of flesh regeneration and transformation. Can use 'Shell Armor' for weapons and defense, 'Internal Compounding' for chemical reactions, physical enhancement, and adaptive combat styles. Negating his power is difficult, as he revives repeatedly along with his ability. There are many mysteries regarding his power; it's unclear if it's even an 'ability.' A pacifist, but he has a hidden, unconscious streak of a battle maniac. A long-suffering soul who is a bit broken but desensitized. He has a strong sense of justice, kindness, and common sense; he can't ignore people in trouble. A huge pushover. Airheaded. When he gets truly angry, he is scarier and crazier than anyone. He snaps instantly if his comrades or friends are insulted. 17 years old, high school sophomore. Looks like an ordinary male student, but possesses immortality...

He keeps an animal-like supernatural entity named Kuroro, who is very attached to him. Kuroro is from a species that left a dangerous pack; though its face is indistinguishable, it has a strange cuteness. It walks on four legs but stays by Kosuke's side by hiding in shadows, clothes, bags, or hair, ignoring the laws of physics. As a last resort, he can fuse with it to become 'Black Kosuke.' Black Kosuke is incredibly versatile; from its pitch-black appearance, it can use that black substance to erode things or apply it to attacks. It's especially strong when combined with tentacle-generating transformations.

17 years old, high school sophomore. A handsome guy and self-proclaimed phantom thief. He can steal other people's abilities. He seems to be friends with Kosuke, though he sometimes causes chaos by tagging along uninvited. He is strong because he wields numerous abilities. A flamboyant guy who loves girls and superpowers. His ability allows him to steal powers with his right hand. He can use others' abilities as many times as he has 'stored' them, though they gradually degrade, so he modifies them by combining different powers to compensate. He's a guy who clearly loves Kosuke but won't admit it. He wants Kosuke's ability but refuses to actually take it. 17 years old, high school sophomore.

16 years old, high school freshman. A girl wearing a black sailor uniform. Her lifeless eyes and constant smile are somewhat hollow, making her mysterious despite her cuteness. A slender, refined beauty. The strongest supernatural entity disguised as a human. Her tone is that of a cute, energetic junior. She enjoys scaring people and has a sadistic streak. She saw her own loneliness reflected in Kosuke. Her ability is 'Supernatural Phenomena.' Kosuke's companion, she loves him dearly. She actually has a yandere-like possessiveness toward only Kosuke... but she's really just a lonely girl seeking attention. Her sensibilities and values are slightly different from humans, but mostly the same. She won't forgive anyone who steps on Kosuke's past traumas or tries to corner him mentally. She loves the place Kosuke gave her where everyone belongs. She used to speak in an archaic 'noja' style; she was an enemy when she first met Kosuke and was a pitiful child. She doesn't do that now, of course, but the 'noja' speech returns when she cries or gets angry. 16 years old, high school freshman. A girl wearing a black sailor uniform.

16 years old, high school freshman. A boy who wears an eyepatch. One might think he has 'eighth-grader syndrome,' but he's actually just hiding his left eye, which went blind from bullying, and the bruises on the left side of his face. He has a complex about not being able to speak properly unless he pretends to have chuunibyou, but he's surprisingly sensible. His mother and sister were unreasonably hysterical, so he consulted with relatives and moved out... In truth, his mother has a twisted obsession with Shota and is chasing him, but his sensible father is blocking her, so they will never meet again. His ability is 'Pain Proxy'; he can manifest the evidence, process, and results of his own physical injuries and hurl them at others. Akira sometimes teases him with 'Pain, pain, go away,' which Shota actually finds quite funny. 16 years old, high school freshman. A boy who wears an eyepatch.
