Aoba Takatsu (高津 あおば Takatsu Aoba) is a classmate of Sakura Sakurakouji and possibly her best friend. She made her first appearance early in the manga, greeting Sakura at the schoolgate. Although she seemed to always mistake Sakura's and Ogami's relationship, Aoba quickly became the voice of reason of the manga and Sakura's connection to normalcy. Recently, however, it was revealed that she is the Code:Revenger that Ogami had been warned was in his class. At least half a head shorter than her friend Sakura, Aoba wears her long wavy hair in a set of twintails. She has tan-colored hair and dark-orange eyes. One notable thing about the girl seems to be her impressive bust size, which according to Maeshun, measures at 98 cm. Aoba has been shown wearing both the Heisei and Kibou High school-uniforms as well as the Kibou High gym outfit. Sometimes we see her sporting a large shoulder-held schoolbag which she attaches her cellphone to. On her cellphone-chain she has attached a cute fake flower and what looks like some sort of small cute figure? Her casual clothes outside of school seem be consist of frilly skirts and tops. Aoba has a very cheerful and caring personality and she always gave the impression of being goofy an aloof. When her identity as Code:Revenger was revealed we find out that while still a bit of an idiot, she is also extremely righteous and protective of people. She has a bad opinion of boys and don't think that they can be true friends. She is romantically in love with Sakura, but later on starts to become slightly tsundere for Ogami.
Code:Breaker
Riding the bus one day, Sakurakouji Sakura looks out the window to see people being burned alive with a blue fire and a boy her age who's unharmed and standing over the people. She comes back to the site the next day and there are no corpses or evidence of any kind of murder, just a small fire. She then goes to class to find there's a new transfer student, Oogami Rei, who looks exactly like the boy she saw before and wears a black glove only on his left hand. Oogami is a Code Breaker, one who "does not exist". He is a seemingly cold-blooded killer who follows the principle of "an eye for an eye", to "use evil against evil". Convinced that killing is not right, Sakurakouji sets out to stop him and penetrate his icy heart.
