A red oni genuinely wants friendship. The village doesn't believe him. That gap, between what he is and what he wants to be, never closes, not even when he tries harder than anything in the world should ask. The blue oni isn't the real villain. Loneliness is. Watch this if you've ever been the thing everyone fears, no matter what you do.
A red oni hopes to make friends with the people of a nearby village, but the task keeps getting harder, because a blue oni is out terrorizing those same villagers. A single-episode OVA, the story blends adventure and fantasy as the red oni tries to win over the humans he wants to befriend while another of his kind spreads fear among them.
