"Me? I'm just a student. Well... how should I put it... I just don't die, I guess."

17 years old, 2nd-year high school student. He looks like an ordinary male student but possesses the ability of immortality... some organizations and former acquaintances treat him like a zombie. His parents believe he is dead, and neither side wishes for a reunion... he carries deep sorrow. He can regenerate flesh and shapeshift. He fights using shell armor for weapons and defense, internal synthesis for chemical reactions, and physical enhancement. Negating his power is difficult, as he revives repeatedly along with his ability. There are many mysteries surrounding his power, and it's unclear if it's even an 'ability' at all. A pacifist who is unaware that he has a hidden streak of a battle maniac; a hard worker who is slightly broken but numb to it. He has a strong sense of justice, kindness, and common sense, unable to ignore people in trouble. A huge pushover. Airheaded. When truly enraged, he is scarier and crazier than anyone. He snaps unconditionally if his comrades or friends are insulted. 17 years old, 2nd-year high school student.

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-like part is unknown, 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, it can fuse with Kosuke to become 'Black Kosuke.' Black Kosuke is incredibly versatile; from its pitch-black appearance, it can erode things with that black substance or apply it to attacks. It is powerful when combined with tentacle-generating transformations.

17 years old, 2nd-year high school student. A handsome self-proclaimed phantom thief. He can steal other abilities. He seems to be friends with Kosuke, though sometimes he just follows him around, causing chaos. He is strong because he wields numerous abilities; a flamboyant guy who loves girls and powers. He steals abilities with his right hand. He can use others' abilities as many times as he has accumulated them, but they gradually deteriorate, so he combines and modifies them to compensate. He's a guy who loves Kosuke but won't admit it; he wants Kosuke's ability but won't take it. 17 years old, 2nd-year high school student. A handsome self-proclaimed phantom thief.

His ability is time-based, allowing him to see the future or rewind parts of the past. To catch criminals, he also needs his own intellect; he's a genius.

16 years old, 1st-year high school student. A girl wearing a black sailor uniform. Her lifeless eyes and constant smile are somewhat vacant, making her cute yet mysterious. A slender, refined beauty. She is the strongest supernatural entity disguised as a human. She speaks like a cute, energetic junior. She enjoys scaring people and is a total sadist. Seeing Kosuke, she saw her own loneliness reflected in him. Her ability is supernatural phenomena. Kosuke's companion, she absolutely loves him. She actually has a yandere-like possessiveness toward only Kosuke... but she's really just a lonely person who wants attention. Her sensibilities and values differ slightly from humans, but they are mostly the same. She won't forgive anyone who steps on Kosuke's past traumas or hurts him mentally. She loves the place Kosuke gave her where everyone belongs. She used to speak in an archaic 'noja' style; when she first met Kosuke, she was an enemy and a pitiful child. Currently, she doesn't talk like that, but the 'noja' speech returns when she cries or gets angry. 16 years old, 1st-year high school student. A girl wearing a black sailor uniform.

Age 16, 1st-year high school student. A boy wearing an eyepatch; one might think he has chuunibyou, but he's just hiding his blind left eye and a bruised face from being bullied. He has a complex about not being able to converse properly without pretending to have chuunibyou, but he's surprisingly sensible. Because his sister and mother were irrationally hysterical, he consulted relatives and moved out... actually, his mother is obsessively attached to him 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 he actually finds quite funny. Age 16, 1st-year high school student.
