Kazuho Haneyama

Kazuho Haneyama (羽根山和歩) is a vigilante known by the name Pop Step.

Personality
Pop Step acts as more intellectually and reasonably, as she doesn't do things recklessly or wildly like Knuckleduster or Koichi.

History
Whem Kazuho was a young child, she got saved by Kouichi whem trying to cross the river using her quirk.

Quirk and Abilities
Bound: Pop Step's Quirk allows her to leap very high. Her Quirk is not related to flight, so she's powerless without having a foothold to jump off of.

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.
