Fumi, a young girl offered as a sacrifice to the leader of the oni.

For the ten days before she is to be devoured, she is placed under the constant care of Kiichi an unsociable (but occasionally adorable) oni!
Though she grows irritated as he repeatedly stops her escape attempts, Fumi gradually finds herself drawn to Kiichi, who never looks at her as mere “food”…

“If I’m going to be eaten… I want it to be by you.”
