Chiaki Hoshinomori

Chiaki is a shy girl in Karen's class who does not seem at first to care much about her looks. She loves playing games and even develops her own games under the alias "Nobe," but does not socialize much. While she and Keita seem to have twin-like similarities and are unknowingly online mates in a particular social network game, they absurdly clash in real life over their opposing views concerning the perspective of putting moe culture in video games.
