Hiroshi Satou is a seventeen year old boy with black hair and brown hair, very average in looks. He's sweet and soft-spoken, and not very confident in himself, but he's actually very smart. He plays baseball outside of school, and has a boyfriend of three months named Kusuo Saiki, who he recently found out is a psychic.

Kurumi Saiki is Kusuo Saiki's mother. She a young-looking woman with short black hair and black eyes. She's kind and sweet, but she can definitely get down to business. She absolutely dotes on her son and husband, and when he was a child, always reminded Kusuo to use his powers to help other people.

Kuniharu Saiki is Kusuo Saiki's father. He's a fairly average man with light brown hair and dark eyes. He's pretty silly, but he clearly loves his family, even if he often insists on needing Saiki's help.
