カタシロ・リョウスケ

A member of Glittering Crux's second section Vanishing Age squad. Head's mark was originally his until he decided to give it to him. He was the fiancee of Takuto's mother Sora, but he gouged out his left eye when he found that Head was having an affair with her. Despite his cold attitude, Ryousuke really did love Sora, and has been shown to be fond of her son as well as Sugata and Wako.
