Sakura's best friend at school and Dekasugi's childchood friend. Like the rest, she knows of Ogami's identity as a Code:Breaker when Yuuki assaults their school.
spoilerAfter revealing himself as one of the Re:Code, Dekasugi exposes Aoba as the Code:Revenger. Although she has not revealed any special power, she is still able to overpower Ogami with mere physical strength and speed.
Aoba's special power is 'time'. She has the ability to revert anything she touches back to how it once was. As an exmaple, If she reverts the objects/persons time back 60 seconds, that person/object will become what it was 60 seconds ago.
