"Fushigi" Toriatsukaimasu: Tsukumodou Kottouten (“不思議”取り扱います 付喪堂骨董店, lit. "Tsukumodo Antique Shop - We Handle "Mysteriosities"") is a light novel series by Akihiko Odou with illustrations by Satoshi Takeshima.
In our world there are objects that go by the name of "Relics". Not antiques or items of classical art, but mysterious things like a stone that brings luck, a doll whose hair grows night after night, or a mirror that shows your future appearance.
The world is big and so there happens to be a shop that offers such suspicious items — the Tsukumodo Antique Shop (FAKE). But as the name suggests, only fakes can be found there. To make matters worse, the shop assistant is a girl whose attendance couldn't be blunter, so the store hardly has any customers at all. However, from time to time a real Relic appears and makes things interesting.
Very well, now let us talk about those who have obtained one of these mysterious items.
