Haruka Yamashita

Eiko's childhood friend, the two were separated when Eiko had to move away. As children, the two of them used to act as superheroes, although Haruka was always little more than a sidekick. Now a high school student, Haruka has grown out of this fantasy. But when she reunites with Eiko in high school, she finds herself being unwittingly dragged back into a similar situation that she was in before, only now it's rather more embarrassing.
