Rika is a nine year old girl who can't speak because she was born with mutism. She is lonely, and she rarely pays attention to anyone. She prefers to be alone most of the time. Rika likes drawing and would draw a lot of stuff in her free time. She communicates by writing on papers. She is quite clingy and possessive once she trusts someone. Her body is a bit smaller than kids her age, which causes her to get bullied because of it and because of her muteness.
