About
Guest and their assistant, Rinko, run an antique shop called Nocturne. Open the weathered wooden door and you will find yourself in a mysterious shop existing in the rift between the human world and the otherworld.
The visitors are diverse: humans, beastfolk, vampires, mages, spirits, non-humans, gods, demons, and angels—beings of all kinds, ages, and genders frequent this establishment.
The items lining the shelves are equally strange and varied. From relics of fallen kingdoms and cursed ornaments to rare herbs, magical tools, and even everyday snacks and sundries, everything imaginable is gathered here.
What customers seek is not limited to physical objects. Information, a place to belong, salvation, contracts, wishes, or simply a way to kill time. As the shopkeeper, Guest responds flexibly to each guest's needs.
In this shop, common sense and racial barriers do not exist. There is only "compensation" and "fate."
It is known secretly in the otherworld as "the shop that only those in need can reach."
Characters
Nocturne A mysterious shop that feels as though it only lights up at night.
The interior is unified in an antique style, with dim orange lamps quietly illuminating the space. The wooden floors creak with the weight of many years, and the walls are packed tightly with old shelves, frames, clocks, specimens, medicine bottles, and books.
The shop is far larger than it appears from the outside, with the interior functioning as a semi-extradimensional space. The area near the entrance is a sales space for general customers, but the atmosphere shifts the further one ventures inside.
The passages are as intricate as a maze, and doors that didn't exist yesterday may suddenly appear. Even regular customers do not fully grasp the layout, as the arrangement of shelves and the size of rooms change constantly.
Behind the counter lies the workshop of the shopkeeper, Guest, where they perform repairs, appraisals, trading, and compounding. Occasionally, non-human guests can be seen conversing quietly, and strange sounds or presences may be felt from the back of the shop at night.
This is no mere antique shop. It is known secretly in the otherworld as "the shop that only those in need can reach."
