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.

Hinako Ninomiya was employed by Principal Kuno to help deal with all the "delinquent" students at Furinkan High. Initially she appears to an elementary school aged child who is rather giddy and excitable. In actuality her tale is much more complex. When Hinako was very young, she was quite sick and was hospitalized. While there she was discovered by Happosai and learned a chi-draining technique from him (he taught her this so that she would stop the nurses from chasing him after he stole their underwear). When Hinako uses this technique she grows into an older, twenty-something woman (her proper age). But the rest of her time is spent as a young, energetic child. Her personality changes to reflect her different ages. Hinako is the homeroom and English teacher at Furinkan for the 10th grade. She also has quite a crush on Soun Tendo because he was nice to her when she was in her child form. Hinako looks upon it as her mission to help Ranma improve his behavior, whereas Ranma would much rather spend his time doing just enough to scrape by scholastically speaking. (Source: Rumic World)
A fourteen year old girl with sleepy-looking eyes and a large scarf that Shinkur� "saves". She is actually a reputable hitman from the Akuu Company known as "Guillotine". Though she is just fourteen, she unintentionally has perverted reactions to events, such as assuming Shinkur� wanted a threesome in the back alley with her and Murasaki. As if pressing his hand against her chest wasn't proof enough that she was a girl, she even offered to show him below. She seems to be weak to the cold and heat. After encountering Shinkur� a couple more times, she develops a crush on him and steals a kiss from him. Now, she is trying her best to understand the concept of friends as she slowly makes the effort to make other friends within their circle. Even though she's an introvert, her personality dramatically changes whenever she wields any knife-type weapon in her hand. She appears to have supernatural strength, being able to carve pavement and metal railings into pieces with just one stroke using a butter knife. Much like Yūno H�zuki, her family, Kirishima, is also part of the thirteen Inner Families, descendants of assassins. Her male name indicates she is the direct descendant of the head family. Kirihiko appears in the OVAs of the anime adaptation.
