Okko starts as a kid who lost everything and decides the way forward is to learn how to take care of other people instead. Uri-bou is a ghost who eats snacks and complains, which is exactly as comforting as it sounds. This show knows that growing up isn't about becoming strong or special, it's about showing up every day at a hot spring inn, feeding the spirits who haunt it, and discovering that being needed by people who aren't alive anymore might be the realest kind of family you can build.

Okko's world shatters when a traffic accident takes her parents. The grieving sixth-grader moves to Haru no Ya, the hot spring inn run by her grandmother, and begins training to become its young innkeeper. At first she resents the lessons, but over time she comes to take pride in the role and commits to it. Uri-bou, a ghost living at the inn, keeps her company, and he is joined by other mysterious friends who help her along. Mixing laughter and tears with a supernatural touch, the story traces Okko's gradual growth as she learns to carry on.
