Ohma

Ohma is a powerful spirit with the ability to command other ghosts. He harbors a deep-seated animosity toward Kayako Miyanoshita and targeted Satsuki and Keiichirou immediately upon his liberation. Containing him required the use of a large bell and significant spiritual energy from an exorcist. To ensure his permanent demise, a sacrifice was made that resulted in the sealing of both Ohma and another entity.
