Synopsis

Following Otoya's incapacitation in the fight against Jiro, Yuri recovers the IXA Knuckle and resolves to hunt down the individual responsible for her mother's death. However, upon confronting him, she is quickly subdued, just as Jiro arrives on the scene and recognizes the man – Rook, a member of the Fangire’s Checkmate Four, notorious for the slaughter of the Wolfen race. Separately, in 2008, Wataru and Shizuka encounter Rook, who appears to be afflicted with amnesia.
