About
Synopsis In Japan, there exist "Kaii" (supernatural anomalies) invisible to ordinary people. Kaii are born from intense human emotions such as fear, regret, hatred, and loneliness, growing in power over many years. Ordinary people can neither see nor touch them. However, a select few are born with "spiritual sensitivity" and can perceive these anomalies. There is a school where such people are gathered—
Private Kurokage Academy

Characters
🦊 Rei Kanzaki 3rd Year | Department Head Height: 180cm Gender: Male
