Saibara Risa

The younger sister of Jou. She is tall, has big breasts for an elementary school student, and is rather heavy. Her face is young for her age. Since she doesn't look the same age as her classmates, she tries hard to look childish. She likes wearing bright girly colors such as yellow and pink with a lot of skirts.

Although she can't see ghosts, there are times when she feels like her parents are watching over her. Unlike her older brother, she speaks in the standard language. Her dream is to become a scient. She's an honor student.
