"If you want to believe in someone... you need to overcome doubt first. Belief without doubt... is simply a lie."

(Killing Game)

Chiaki usually has a quiet and sleepy look on her all the time, but she becomes a bit more lively when she talks about games or plays them. She has the unusual habit of accidentally falling asleep or forgetting to breathe while playing video games. Despite her habit, she’s a very kind and sweet girl who has no issue introducing her love of games to the people around her.
