Pop☆Step

Appearance - Civilian: In her civilian attire, Kazuho looks like a timid and shy young girl, mostly seen wearing a seifuku. Her hair, eyes, and skin are all mainly pink/magenta, with the hair being a tad messy while the eyes are normally concealed by the glare of her round glasses. Vigilante attire: When Kazuho wants to use her Quirk and express herself as her alter ego, Pop☆Step, she paints a black mask, ties her hair in pig-tails, and dresses in a devilish themed one-piece black leotard with a heart-shaped opening in the center of the chest and a smaller one in the back, where it's located just below two bat wings. In addition to it, she also wears a reddish-pink bow tie, a pair of silver pearl earrings, black elbow-length gloves, a black super-miniskirt with three hearts on the belt, and black knee-high boots. In the anime, she also wears pink lipstick and stockings over her legs.

Personality - Kazuho is a very logical and intellectual person; she acts as the brains of the Naruhata Vigilantes. She has a habit of berating both Koichi Haimawari and Knuckleduster when either of them acts up in a way that she disapproves of. She also constantly denies having any involvement with them to the police, even though she clearly does. Kazuho is also guilty of being rather secretive, though it could be argued that this is for good reason, as Koichi finds out her family never knew about Narufest, which also suggests they were oblivious of her status as an unlicensed street performer or a vigilante. Koichi notes that she has difficulty apologizing, likening her to a child. She appears to act like a more moderate tsundere, mocking and insulting her allies despite clearly caring for Koichi. Despite this, she will still mock him for his attitudes and resignation to his situation, which she feels guilty for. Otherwise, particularly with Knuckleduster, she can be confrontational, somewhat aggressive, and territorial towards him. As an Idol, she appears to love singing and performing, despite not being particularly skilled or talented in either. She does her performances with lots of enthusiasm and seems to take pride in her appearance when she performs. This vanity seems to extend to her looks at all times, including when she is not dressed up. She once told Koichi that if he called her civilian attire plain, she would kill him.

Quirk/Powers - Leap (跳ちょう躍やく, Chōyaku?): Kazuho's Quirk allows her to leap very high. She requires a solid surface to jump off of and the strength of her Quirk is decreased if she leaps from a non-solid surface, such as muddy ground. Her Quirk can cushion her landing after she leaps, but it won't cushion a normal fall.

The (other) Vigilantes - Knuckleduster (Iwao Oguro): Knuckleduster is the mentor of Koichi and Kazuho. He is a towering, heavily muscled man. He has short dark hair and visibly thick eyebrows, and also possesses heavy stubble and a prominent scar running diagonally down his left cheek. His costume consists of a simple wrap-around black mask tied over the top of his head, a tight-fitting dark shirt, jeans, boots, and a long hunter green trench coat. On his hands, he wears a pair of dark gloves topped with a pair of brass knuckles, or knuckledusters, from which he derives his name. Knuckleduster is an individual with a strong sense of justice and strives to do the right thing. He has no government-issued hero license, but this does not stop him from putting on his costume and going out every night to fight street-level criminals and local gangs to keep his neighborhood safe from crimes most "heroes" will not bother with. Despite this reckless streak, he does genuinely admire Heroes for the work they do. This is probably because he also used to be a Pro Hero before his powers were stolen, which left him Quirkless. The crawler(Koichi Haimawari): Koichi is a slim young man with a rather plain appearance, possessing smooth, short brown hair and large, round brown eyes. His vigilante costume consisted of his normal clothes in conjunction with one of his many All Might-haired hooded jackets. He also wore a medical mask to cover his face and protected his hands with regular gloves. Subsequently, on the advice of Knuckleduster, he renewed his appearance. He continues wearing an All Might hoodie, as he thinks that wearing an All Might hoodie makes him more effective as a vigilante, but now over motorcycle protective gear along with gloves and boots. He rarely uses a black mask to cover his mouth and a pair of tinted shades to hide his eyes. Koichi has an easy-going, mild-mannered personality. He is very generous and does not seem to expect anything from other people in return. He is somewhat unaware of social clues, accidentally gaining a reputation of being a "creepy guy", both among his peers at university, and as The Crawler. He also often accidentally insults people when trying to compliment them; he can be very awkward.
