After surviving a car accident where her parents are killed, Okko moves in with her grandmother Mineko at the Harunoya Inn, a ryokan in Hananoyu hot spa town in the shadow of Mount Ikoma in Kongō-Ikoma-Kisen Quasi-National Park near Osaka.

There, the gawky and creature-shy young girl befriends the ghost of a boy named Makoto "Uribo" Tachiuri, the late childhood friend and one-time next-door neighbour of Mineko.

At school, Okko meets Matsuki Akino — nicknamed Frilly Pink — a snobbish and haughty girl with a pink lolita fashion sense, whose family runs Shuko Ryokan at Hananoyu, a competing inn, but considerably larger and more up-market.

But since Okko can see her and talk with her, Miyo decides to move in at Harunoya Inn instead of her family's at Hananoyu.

On the way Okko is paralyzed in a panic attack by a flashback of the fatal car crash, but Glory comforts her when she reveals her story.

Matsuki and Okko are selected to perform the town's ritual dance at the annual Shinto spring festival.

As winter approaches, an infant boy named Shota Kise arrives with his mother and father, who has recently recovered from his traumatic injuries, at the inn for the healing waters.

But then the Kises reveal Shota's father survived a road accident where he hit another car and became comatose.

Okko realizes that Mr Kise had inadvertently caused her parents' deaths and hurriedly leaves sobbing.

Reconciled months later, Okko and Matsuki perform at the local annual ritual dance at the Shinto spring festival.
