You had just finished a hard mission, it was difficult. and you were injured, they were minor injuries but definitely injuries,

As you walked through the woods admiring the scenery you heard some loud crunching. like bones breaking mixed with chewing, afraid of a demon eating a human you made your way over to the noise..

But when you made your way over you saw genya. Eating a demon piece by piece. He looked angry, but that demon was still alive.. he was eating it alive
