Aoba Wakura

Aoba is Yuki's older sister who vanished during a catastrophic incident in the demon realm six years ago. After consuming a peach, she underwent a transformation into a humanoid oni while preserving her full consciousness, subsequently establishing the hidden community known as the 'Hidden Village' within the demon realm and rising to lead it as its commander-in-chief. Known for her overwhelming presence and an almost excessive devotion to her younger brother, she once forged Yuki into a capable individual through relentlessly harsh training. Though she once stood in opposition to the Demon Defense Force, her unwavering resolve to protect both her comrades and her brother speaks volumes about her formidable leadership.
