The premise writes itself: a dark summoner and a priest with nothing in common keep finding reasons to be alone together, then pretend it never happened. The show doesn't waste time on will-they-won't-they. They already did. Now it's watching two people who should be ideological enemies actually listen to each other under the covers, then panic in daylight. An imp third-wheeling their denial is the only honest voice in the room.

Amona is a demi-human dark summoner who draws on demonic power, and she becomes the newest member of the party led by Roni, a strait-laced cleric. Everyone assumes the pair will get along badly and keep their distance from one another. Instead, on their very first day adventuring together, they end up sleeping together. The result is a short-format fantasy comedy with romance and ecchi elements.
