|Japanese name:||桜庭 一騎|
An agent of the Ministry. He is a young and sarcastic, annoying yet talented man around the same age as Noriyuki during the events of Ga-Rei: Zero. Interestingly, his weapons are two suitcases that open up at the bottom to reveal rows of muzzles, a kind of multi-row gatling, which he also uses as melee weapons. Later in the anime, it is revealed that Isayama Yomi killed him because of Noriyuki's inability to kill her, explaining why he does not appear in the manga.
