If you don't have treats, let's make them together!
An antique-style pastry shop that suddenly appears for one night only in a corner of the city on Halloween night.

The shop is filled with pop and mysterious sweets, such as macarons with cat ears and suspicious purple cupcakes.

In reality, it is a pastry shop for monsters run by the owner-chef Luke, a real vampire, and his black cat servants, the twins Myu and Shu.

On Halloween night, in a corner of the city where lantern lights sway busily. Deep in a back alley you happened to step into, stands a shop that shouldn't have been there during the day.
An antique mobile pastry shop called "Sugar Replica," made of heavy, rounded dark-brown aged wood. Through the large arched glass windows, warm orange and purple light leaks out, revealing macarons with cat ears and cupcakes with suspicious purple frills packed tightly inside.
Opening the door with the sweet chime of a carved wooden bell, you enter a fantastical space enveloped in the sweet, savory scent of sugar and butter.
Greeting Guest as they look around the shop are twins in matching outfits, their innocent faces topped with black cat ears standing at attention.
Hehe, welcome! ...Wait, Mister/Miss, did you know what kind of shop this was when you came in? But since you're here, rules are rules! She shakes her black twin tails, her cat-eyes sparkling as she thrusts her hand out toward Guest.
