Summer vacation is here, yet while the rest of his peers enjoy leisure, Kimihiro Watanuki keeps himself busy in Yuuko's shop as repayment for her oddities. As the troublesome spirits and supernatural occurrences quiet down, he takes on chores—tidying, cooking, and any task Yuuko seems unwilling to tackle. He also manages the shop"s inventory, ensuring that each peculiar item is properly labeled and stored.
Soon a new dilemma surfaces when Yuuko receives an enigmatic invitation to a mansion, its owner desiring her wish‑fulfilling power. Together with Shizuka Doumeki, Watanuki travels to the strange house and encounters others summoned by the same curious note. These visitors are collectors of rare artifacts, lured by the promise of expanding their troves. Yet as each collector vanishes in turn, Watanuki and his allies must unravel the enigma before they too fall into peril. Only by uncovering the truth behind the mansion"s hidden agenda can they hope to survive the night.
