春日野 三咲

Shigure's classmate who is a popular girl. Her friendly and honest personality gave Misaki the popularity she currently has. When she is embarrassed, she has a habit of flailing her fists around. She also tends to sometimes run away when she's teased, but that's also part of her overall charm.

Because of her personality and for the fact she is extremely cute, the guys around her think she must have a boyfriend and which is why nobody attempts to confess to her. However, because of that fact, her relationships with her classmates have never become anything deeper or genuine like "friendship". She becomes interested in Shigeru after he told her about gojoken, and survived through their tests thanks to the cheat sheets she bought from there.
