After falling asleep while playing an adult fantasy game, Itsuki Kusaka awakens in another world and is given an unusual mission by a goddess. Rather than defeat a demon army, he is asked to teach the goddess’s holy disciples about intimacy and relationships they have never been prepared to understand. What initially sounds like an easy fantasy becomes an awkward educational assignment that forces Itsuki to navigate unfamiliar customs and responsibility rather than simply indulge his expectations.
