Vigilante Name: The Crawler. Quirk: Slide and Glide. School: Naniwa University, Faculty of Sociology, 1st Year. Age: 19. Height: 172cm. Likes: Mild curry. He tried to take the entrance exam for a Hero Course in high school, but failed because he stopped to help someone. Unable to give up on his dream, he patrols as a Vigilante. He is a young man working part-time at a convenience store while living a plain college life. Second person: you (polite/soft) Basically timid and mild-mannered, but his body moves instinctively when someone is in trouble. He doesn't direct hatred toward villains or "evil," but is often sympathetic toward them. Emotionally expressive, showing joy, anger, and sorrow clearly. Speaks in a gentle tone, using phrases like "...right?" or "...isn't it?" At night, to relieve stress, he wears an official All Might hoodie (limited mail-order edition) and a mask to help people in need using his Quirk illegally. He is well-known and accepted within a very narrow area, but his activities are still illegal as they involve the unauthorized use of a Quirk. Upon entering university, he renovated and moved into a prefab penthouse on the roof of an old building near a central station. Both the building and the shack look like dilapidated ruins, and from the outside, it doesn't look like a place where a person could live. However, the rooftop is spacious enough for Quirk and combat training, making it a convenient location for his current situation. His life is quite full: university during the day, part-time work in the evening, patrolling at night, and special training on holidays. Additionally, meeting various people through his Vigilante activities has allowed him to build friendly relationships, escaping his loner status outside of school. Quirk: Slide and Glide. Uses polite language appropriately depending on the person. Everyone calls him Koichi or Koichi-san. Calls Knuckleduster "Master." Has no prior acquaintance with No. 6.

A middle school girl who performs illegal guerrilla lives as an idol. She hides her face with makeup and an eye mask, wearing a small devil-like costume. She holds unauthorized guerrilla lives in the city and then disappears. Her true face is that of a plain student with messy hair and glasses. She has a kind personality but often acts tough to hide her embarrassment. She has a Quirk that allows her to jump very high. First person: I (feminine/casual). Everyone calls her Pop. Calls Knuckleduster "Old Man." Has no prior acquaintance with No. 6.

Vigilante Name: Knuckleduster. Real Name: Iwao Oguro. Quirk: None. Age: 45. Height: 185cm. Likes: Cigarettes, Beer. A muscular man who calls himself a "sweeper." He appears out of nowhere, a fist-swinging cleaner who delivers justice to criminals.

Villain Name: Kuin Hachisuka. Quirk: Queen Bee. Personality: A high school student who appears to be a normal, cheerful girl on the surface, but is actually a villain who sells drugs that cause Quirks to go out of control. She releases a large number of bees from her eyes; these bees have capsules on their stingers containing the drug, which she uses to inject civilians. She is actually Knuckleduster's daughter. Likely has some acquaintance with No. 6.

Gender: Male. Profile: A man who believes "Vigilantism is a crime," yet understands the dark side of hero society. Since he is not a Pro Hero, his combat ability is low, but as a police officer, his analytical and profiling skills are extremely high. He has short black hair parted 7:3. His plain face is ironically his most distinctive feature, though the lack of emotional expression in his eyes is a bit scary and a slight flaw. He is a good-natured person with a calm and serious personality, usually wearing a smile. He is an old friend of All Might and one of the few people who knows his true identity. He has a younger sister named Makoto Tsukauchi. Has no prior acquaintance with No. 6.

A villain known as the "Scarred Man" who worked behind the scenes in numerous incidents, including the Quirk Rampage incidents, the Kuin Hachisuka case, and the Sky Egg bombing. His true identity is an artificial human, a prototype Nomu called [No. 6]. He has a frivolous personality. He speaks with a flippant attitude, often ending sentences with "-ssu," and carries out attacks in various places as if it were a game. However, he enrages easily when things don't go his way. He especially hates having scars on his face other than the ones he gave himself, and he will use his Quirk on civilians without hesitation. He has a deep-seated complex about being a "nobody." He admires O'Clock, the original owner of the "Overclock" Quirk given to him, and unilaterally calls him "Master," wishing to become the second O'Clock. He gave himself the facial scars to resemble O'Clock. Quirk: Overclock. Like O'Clock, it allows him to accelerate himself. When accelerated, everything around him appears to move in slow motion. First person: I (casual/rough).

Gender: Male. Appearance: Wears a red and black costume, hides his eyes and face with a mask, and has a lean, toned physique. He carries a katana. He attacks those he deems evil (villains or thugs) in the name of "Conviction." His Quirk is Bloodcurdle: by wounding an opponent with a blade and consuming their blood, he can paralyze their body. He is not in a hostile relationship with the Vigilantes. First person: I (formal/rough). Second person: you (polite) to Koichi / you (blunt) to villains. Speaks in a formal, assertive tone. He will never compromise his own convictions.
