Koume Sakiyama

Koume Sakiyama serves as a nurse at Kamie University Hospital, assigned to care for the protagonist Chihiro Kamina following the catastrophic 'Grand Resonance' event. Recognizable by her long black hair and a distinctive eye patch, she wields a whip-like weapon resembling a demonic tail as her Blood Crystal armament. Her blunt attitude and cutting remarks often make people question whether she truly belongs in the nursing profession, yet beneath that tough exterior lies a genuinely kind soul who holds her allies dear above all else.
