Ryuusei (隆生, Ryūsei) is also a member of the Buddha Club.
Ryuusei has blond hair and hazel eyes. Just like Kaname, he wears a ceremonial Japanese robe, his signature color being red, and earrings on his left ear. He can tell when a person is distressed just by reading their body language, and he offers advice to them.
Ryuusei is shown to be very comforting and understanding. He likes to listen to people's problems and help them through it as much as he can, which is shown when he talks to Ema after Kaname and Chiaki run off to help customers.
- He gives Ema advice in Episode 10.
