Welcome to the Raison d'Etre Antique Shop

Luciole, who grew up in an orphanage, is cast out from her workplace and wanders into an old Western-style mansion. There, she finds a mysterious antique shop — a place where "souls with no place to belong" eventually arrive. The shop’s owner exudes an aura that is clearly not human, and the items for sale appear in strange forms — growing tails or taking on human-like appearances…!? This is the tale of a lonely maid with no family, who discovers the meaning of life under the care of a non-human master!
