Kazuho Haneyama

Kazuho Haneyama (羽根山 和歩) is a vigilante known by the name Pop☆Step (ポップ☆ステップ).

Personality
Pop Step is a very smart and Intellectual person, as she acts as the brains of the vigilantes. She has a habit of berating both Kouichi and Knuckleduster when either of them act 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.

Kouichi 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 Kouichi. Despite this, she will still mock him for his attitudes and resignation to his situation, which she feel guilt for. Otherwise, particularly with Knuckleduster, she can be confrontational, and 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 isn't dressed up. She once told Kouichi that if he called her civilian attire plain, she would kill him.

She feels guilt and genuinely is apologetic towards Kouichi for an incident in the past, which resulted in her being saved by him, though at the cost of him missing an examination to attend a Hero High School, thus ending his dreams of becoming a Hero. While she wants to thank him and apologize to him for saving her, she seems unable to do this easily, particularly around other people.

History
When Kazuho was a younger, she fell into a river when trying to cross it using her quirk. On his way to take his hero-course entrance exam, Kouichi saved her from drowning.

Quirk and Abilities
Bound: Pop Step's Quirk allows her to leap very high. However, in order to do this, she needs a solid surface to jump off of. Her Quirk is not related to flight, so she's powerless without having a foothold to jump off of. She can't use her Quirk when falling onto an object, but if she leaps off of an object, she will land safely, meaning that when she leaps, her Quick activates and protects her as she falls, but this won't occur unless she leaps first. Her Quirk can also be less effective if she is on a none-solid object, such as muddly ground, and this can limit her leaping distances.

Kouichi Haimawari
The two met when Kouichi tipped Kazuho off about the police arriving for her. She thanked him for his help and the two became friends and fellow Vigilantes. While she does not partake in the Vigilante missions as actively as Kouichi, she still supports him during the missions through other means besides combat related. As they are both Vigilantes, Kazuho trusts Kouichi enough to reveal her public image.

Though they are friends with one another, the two have bickered over disagreements regarding Kouichi's path as an illegal hero. Nonetheless, she still supports him.

It is revealed that Kazuho and Kouichi met before when they were younger. Kazuho had fallen in the river and couldn't swim despite the shallow water. Kouichi jumped in to rescue her and immediately left when he was running late. Kouichi appears to not remember Kazuho from this encounter due to the limited interaction between them back then. However Kazuho remembers Kouichi because of the jacket he gave her after being rescued. She kept that jacket as a remembrance of that moment. She also apparently has been watching Kouichi from a distance before they properly met one another.

Kazuho appears to have a crush on Kouichi while Kouichi doesn't appear to reciprocate and is oblivious to her affection. Despite this, he treats her as a valued friend.

Knuckleduster
The two are fellow Vigilantes, but their relationship can be deemed as a rocky one as both tend to bicker with one another on more than one occassion. Kazuho does not not appear to tolerate Knuckleduster's aggressive and violent attitude, especially when it gets out of hand. Despite that, the two are capable of working together during Vigilante missions.
