Rio Mosuka (リオ・モスカ, Mosuka Rio) is son of Saki Hanajima. His father is a foreigner.
He is a third year middle school student and a member of the Go club (dedicated to the ancient board game), along with his friends Shiki Souma and Chizuru Souma.
- According to his uncle, Megumi, his mother's mysterious psychic abilities don't transfer to male family members, so presumably, Rio is a normal kid.
