Rook

The Lion Fangire (ライオンファンガイア) is known as the Creation of Heaven and Earth, listening to the Baby's Cry and the Angry Roar (天地開闢, 産声と怒号を聞きながら). He is from Beast Class of Fangire subclass.

Rook
Rook (ルーク), named after the Rook tattoo on his hand, is the human form of the Lion Fangire and a member of the Checkmate Four. The Rook is the one Yuri Aso swore vengeance on for murdering her mother, as well as being the one who slaughtered nearly the entire Wolfen Race. Being one annoyed with boredom, the Rook devised his own personal game: the "Time Play". In a Time Play, he feeds on a select group of people within a time limit, with failure to make the intended number resulting in self-punishment with an electric shock strong enough to kill a human. However if he manages to succeed the right amount of victims within his game, he rewards himself with ice cream. Eventually he is defeated by Yuri when she tricks him into using the Ixa System to weaken him before Otoya Kurenai and the Arms Monsters further weaken him for Yuri to deliver the deathblow with the Ixa System. However, the Rook barely escapes with a severe wound on his right shoulder, entering a deep rest to recuperate from his injuries.

By 2008, the Rook has lost his memories while resting and possesses a child-like mentality, found by Wataru Kurenai and Shizuka Nomura. Because he cannot remember his name, they call him Dai-chan (great) due to his size. Soon after, Dai-Chan regains all of his memories as the Rook upon seeing one of his old battlefields. However, the Rook becomes bored with his Time Plays and now resorts to playing the ultimate game, doing good deeds before getting himself killed to enter the pearly gates. This plan is changed when the Rook seeks to destroy Ixa, eventually being destroyed by Megumi Aso as Ixa attacking his shoulder.
