A mysterious blond youngster who is an acquaintance of Shuichiro. During Shuichiro's coup d'état and the second Apocalypse outbreak, Yuu is revealed to also possess the Power of Kings when he kidnaps Inori and uses her void to kill Shu only for Gai to save him. Gai recognizes him by the title "Death Grave Keeper".

Shuu's entire world was shattered after a meteorite crashed into Japan, unleashing the lethal Apocalypse Virus. The chaos and anarchy born of the outbreak cost Shuu his family and reduced him to a timid, fearful shell of the boy he'd once been. His life took another unexpected turn after a chance encounter with the stunning pop star, Inori. This mysterious beauty introduced Shuu to the King's Right Hand: a genetic mutation that allows him to reach into hearts of mortals and turn them into weapons.<br>
<br>
Shuu finds himself caught in the crossfire between those who desperately seek his newfound strength. On one side lurks a clandestine government agency, and on the other, Inori and the spirited band of rebels known as Funeral Parlor. The choice is Shuu's to make - and the world is his to change.<br>
