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. Later on, he's shown to take the form of a crowned young boy inside Ogami. According to him, this form is merely temporary, due to the lack of his full original strength. In the Meiji era, the Emperor, along with Heike, Sakurakouji Sakurako, and one other person, founded Eden.

The protagonist/antihero. Ogami Rei is a mysterious young boy about whom not much is known. Sakura first witnesses him burning people with a blue flame in a park; the day later he transfers to her school. When Sakura confronts him about his killings, Ogami reveals to her that he's in fact a "Code:Breaker", a secret government agent who punishes those who can't be punish by the law. His code number is 06, meaning he's the weakest member of the Code:Breakers. He believes strongly in the idea behind the Code of Hammurabi, often citing the quote "Eye for eye (ç›®ã�«ã�¯ç›®ã‚’, Me ni wa me wo), Tooth for tooth (æ¯ã�«ã�¯æ¯ã‚’, Ha ni wa ha wo)" and adding on "EVIL for EVIL (悪ã�«ã�¯æ‚ªã‚’, Aku ni wa aku wo)". Externally, Ogami is an aloof, uncaring person who is whole-heartedly dedicated to punishing evils and cares for not much else, but Sakura gets closer to him she realizes that his actions often belies his cruel words. Ogami's power lies in his left arm, which burns anything he touches with a blue flame. It's later revealed that this blue flame is only a part of a set of seven flames, named after seven demons, which are said to "incinerate the seven deadly sins". In return for these powers, Ogami has to give up something as compensation. So far, the revealed flames are: - Blue flame - Satan - the flame Ogami uses most often. It can incinerates everything Ogami touches. Ogami sacrifices his sense of taste for the use of this flame. - Black flame - Belphegor a.k.a the blaze of limbo - a flame which can burn any special power "tainted with the seven deadly sins". The Code:Emperor takes the power of "Sound" Yuuki partly transfers to Ogami as payment for this flame. When Ogami overexerted his special power, his Lost form results in a severe cold. However, it's later revealed that Ogami's true Lost form is invisibility.
