Satoshi is Mayu's cousin. He makes friends with Rii soon after Rii starts attending their high school. They get along well because they both are into martial arts and love to tease Mayu. Satoshi secretly develops a crush on Mayu's best friend Naoko that only Mayu knows about. She works to set the two of them up. Satoshi's family heritage traces back to the toshis of centuries ago. The evil of their bloodline was washed out over time, however.
