Takatsu Aoba

Aoba Takatsu (高津 あおば Takatsu Aoba) is a classmate of Sakura and possibly her best friend. She made her first appearance early in the manga, greeting Sakura at the schoolgate. Although she seemed to always confuse Sakura and Ogami's relationship, Aoba quickly became the voice of reason of the manga and Sakura's connection to normalicy. Recently howerver it was revealed that she was the Code:Revenger that Ogami had been warned was in his class.

Appearance
At least half a head shorter than her friend Sakura, she wears her long wavy hair in a set of twintails. At this time her hair and eye color are not known but it seems her hair at the very least is of a light color. One notable thing about the girl seems to be her impressive bust size which according to one of her childhood friends measures at 98cm.

Aoba has only been seen wearing her school-uniform and 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? Recently (although of not of major importance) it was revealed that she wears, or at least at the time wore, skimpy underwear.

Personality
Aoba has a very cheerful and caring personality, and she seems to be willing to at least protect her own classmates. If this is just to protect her chance at having a normal life or if she actually cared for her classmates has not been shown yet. Aoba always gave the impression of being goofy an aloof, but when her identity as Code:Revenger was revealed to all her classmates she shocked her friends by showing them a somber face. After that she showed them her serious side.

Background
Despite having been given the most spotlight among all of Sakura's classmates (and being the third character of the regular cast to be introduced), very little is actually known about Aoba. She is the childhood friend of both Uesugi and Maeshun and they have known each other ever since elementary-school possibly even earlier. Despite this however it seems that Maesun was totally unaware of of Uesugi and Aoba being powerusers. According to Maeshun though, Aoba was always closer to Uesugi so it might not be that strange.

History
As a student of Kibou high school, Aoba is introduced as Sakura's best friend. When Ogami transfers to their class, Aoba remarks on him being the son of a millionaire and is among the first students that support the theory that Sakura's interest in him is of a romantic nature.

Even having been taken a hostage by Hitomi at one point, Aoba continues to seem blissfully unaware of what is really going on. At on point she along with with a close knit group of their other classmates even visits the Shibuya mansion.

But things aren't always the way they seem as it turns out that Aoba was working for Eden, just like Ogami. Her secret identity being that of a Code:Name called 'Revenger', she had been watching over Ogami and Sakura since day one.

Aoba continued to stay hidden but when Eden ordered the hunt for Ogami her own school became a battleground. Aoba's identity as the Code:Revenger was revealed in front of all her classmates by her childhood friend Uesugi Hajime. Trying to deny it her secret identity at first, she belatedly accepted that her cover was blown and attacked Ogami.

Leaving Heike to deal with Ogami and 'clean up', she fled the school. Uesugi tried to follow her but she beat him up and left him outside of the schoolgates. Her life at Kibou High ruined she was last seen transferring to Hesei high academy where Toki and Saechika also are students.

Time-change in Object
Time Change in Object is an ability that allows Aoba to rewind or fast-forward an objects time. She administers this power by putting here right hand the object she wants to affect and declaring how many seconds she wants the time to move.

Note: Allegedly, Aoba can only use Time Change in Object with her right hand.

Vital Acupuncture
Vital Acupuncture allows Aoba to perform acupuncture on any object or flesh without touching them, shattering the object or strengthening the body. Used in combination with her "Time Change in Object", this allows Aoba to always return herself body to the point in time when her power is at its maximum state.

Hand-to-Hand Combatant: She has shown proof of being an excellent fighter. Exactly how good she is hasn't been made clear yet because so far she has just pummeled her opponents.

Enhanced Strength: She is strong enough to punch a hole in a concrete wall.

Enhanced Speed: While we haven't been given any exact figures she has been shown to be able to move fast enough to blur and create afterimages. Since Ogami had a harder time fighting her than he did Yuuki, it is possible that she is even faster than Code:Breaker 03.

Relationships
Sakura Sakurakouji

Sakura seems to be Aoba's closest female friend. Aoba is constantly seen cheering Sakura on from the sidelines and she doesn't seem afraid of sharing some friendly advice concerning the other girl's lovelife. At the moment it is unclear, but it seems likely that Aoba being in the same class as Sakura was because she had been ordered to keep an eye on her.

Uesugi Hajime

One of Aoba's childhood friends and the person she seems to be closest to. According to Maeshun she always depends on Uesugi too much. It is unclear at this time whether she was aware that Uesugi was a Re:code, but it is shown that he was aware of her identity as the Code Revenger. Even so he seems to care deeply for her and only tried to peacefully stop her without hurting her when she attacked Ogami.

Toshiya Maeda (Maeshun)

Maeshun is also a childhood friend of Aoba but unlike Uesugi he didn't seem aware of her being a poweruser. Maeshun seems to be in love with Aoba although he hides it under a face of only being interested in her breasts. Aoba seems to be aware of his feelings but don't share them. She does however seem to understand them since she gave him a chocolate for Valentine's Day.
