Hoshizaki Ouka

Screen name: Cerasus
Class: Esper

Shuuho's class representative. Diligent and hardworking girl, she often complains because he's always talking about games. She is very close to the new transfer student Anon, and after getting fed up with the talk of Wizard Generation, she declared that she will try it once and that will be it, but ended up getting hooked. Originally she often complained about the vigilant Anon, but ended up becoming friends with her. She is always in distress because of her rashness. Because she barely knew anything about the game, Shuuho taught her how to play it.

Spoiler

Ouka is blood related to both Anon and Ayame. She is revealed to be their relative. So in a way she is their cousin
