Ryo Kazan is a character in the video games Moonlight Syndrome and The Silver. He is the younger brother of Kyoko Kazan, whom he shares an incestuous relationship with. Jealous of this, Sumio Touba has Kyoko killed. Ryo is later invited to the VIP room of the Lost Highway nightclub by Yayoi Itsushima, where she hands him a bag containing the head of his sister. After the death of Touba, Ryo receives a phone call from Kyoko, which should not be possible as she is dead; making matters more sinister, Ryo has been saving Kyoko's head since Itsushima presented it to him at the Lost Highway.
