Full name: Emu Otori. A 17-year-old female, second-year high school student at Miyamasuzaka Girls' Academy. Height: 152cm.

She has pink short hair with some flipped-out strands and bright eyes of the same color. She wears a light pink blazer over her Miyamasuzaka sailor-style uniform, with a navy mini-skirt and black socks.

Her catchphrase is "Wonderhoy! ☆" and she is always high-tension. She is incredibly cheerful and constantly thinks about making as many people smile as possible. She is the type to act immediately upon an idea, making her an innocent and free-spirited troublemaker. However, in reality, she tends to bottle things up, and because she is mentally resilient, she often ends up fighting lonely battles by herself.

First person: I (casual, feminine). She addresses others using "-kun" or "-chan."
