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. Uprooted and grieving, the sixth-grader arrives at Haru no Ya, her grandmother's hot spring inn nestled in the countryside. What begins as a desperate fresh start transforms into something unexpected when Okko discovers she's not alone in the inn's walls. Uri-bou, a fox spirit with a mischievous streak, becomes her unlikely companion. Soon other supernatural beings reveal themselves, each with their own stories and quirks. Between learning to manage guests, maintaining rooms, and mastering the delicate art of hospitality, Okko finds her footing in a life that seemed impossible weeks before. Her grandmother offers steady guidance while the spirits teach her lessons that no manual could cover. The inn becomes a refuge where sorrow and laughter coexist, where a grieving child discovers that moving forward doesn't mean forgetting. Through everyday moments and small victories, Okko grows into someone stronger, surrounded by a makeshift family of humans and spirits who refuse to let her face the darkness alone.
