Aoba Takatsu

As Sakura's closest schoolmate and a lifelong friend to Dekasugi, this powerful figure holds the secret of Ogami's true identity. Though initially appearing as a regular student, she is revealed to be the formidable Code:Revenger. Utilizing "Time-Change in Object" to revert matter and "Vital Acupuncture" to manipulate physical strength, she can even maintain her peak physical condition. Despite her immense speed and strength, she occasionally reverts to a frail, elderly form.
