Having lost both parents, Miyo Yamaguchi ends up in the care of an aloof uncle and a stern aunt who is impatient to find her a job. After consecutive failed attempts, luck finally smiles on the wretched orphan when she lands a sales clerk position at a curiosity shop. Despite not meeting the requirements, Miyo possesses a rare ability that piques the interest of the shop's proprietor Momotoshi Koura: upon touching an object, she can tell who its past and future owners are.

Along with the exotic merchandise from distant countries, Momotoshi's whimsical demeanor and his assistant Ganjii's menacing appearance cause Miyo to feel like Alice straying in Wonderland. Nonetheless, the two prove to be very supportive—guiding her through this fascinating environment. As she adjusts to her new tasks, little does Miyo know the descent into the rabbit hole opens not only an exciting chapter in her life, but also the doors to a miraculous world that is bound to change her destiny forever.
