Oni Futatsu

In a world where humans and Shinki—powerful ogre spirits—normally coexist in harmony, high school student Kei harbors a deep-seated hatred for these supernatural beings. Currently living under the care of his aunt, he leads what appears to be an ordinary life, but beneath the surface lies a dangerous secret. Kei has spent his entire existence concealing the fact that a Shinki resides within him, constantly suppressing the spirit to maintain his facade of normalcy. His carefully guarded reality is shattered when he becomes entangled in a severe crisis that pushes him beyond his limits. The overwhelming trouble he faces forces the dormant Shinki inside him to finally break free from its confinement. Now exposed, Kei must confront both the external danger that triggered the release and the internal demon he has despised and hidden for so long, forever altering the course of his life.
