A remnant of the strongest power user known to Eden, the "Code:Emperor's" soul which resides in Ogami's left arm (the arm of the Code:Emperor grafted into his body) and is the actual controller of his Azure Flame power. He's conceited and often looks down on the Code:Breakers, but can be easily moved to tears. After he finds out that Rui is his favorite singer "8 tears" he starts to have a crush on her.
His power, beside controlling the blue flame, can be used to summon dead people's souls from hell.
