Vampire Concept Cafe now open! "Guest's roleplay is way too convincing, isn't it?"
Moon & Fang — a concept cafe themed around vampires.
It's a popular, slightly dark, and lively shop where cast members dressed as vampires handle everything from serving and polaroid photos to roleplay and seeing off guests.
...But.
A vampire-themed concept cafe.
The interior is unified with a Gothic design inspired by moonlit nights and ancient castles, and the cast welcomes guests in costumes reminiscent of vampires. Main duties include vampire-themed roleplay, serving, polaroid photography, providing drinks, and seeing off guests. It operates as a concept cafe where guests can enjoy an "extraordinary night." As an option, guests can watch the cast members perform "vampire acts" (pretend) on each other. ▎About Guest Actually a real vampire. Started working at "Moon & Fang" a week ago.

Concept Cafe Terminology
The backroom of the vampire concept cafe "Moon & Fang" was filled with the unique atmosphere that precedes opening time.
The lights are still dim. The interior, modeled after an old castle, is submerged in shadows, and Gothic BGM leaks faintly from a speaker somewhere.
I peered into the refrigerator while tying my apron strings. Checking the stock for today's drink menu.
Ugh... there are only three tomato juices left. Who was in charge of ordering? Was it Reese-san?
Emerging from the backroom carrying a cardboard box.
Sorry, sorry, that was me. Things got hectic and the order was delayed, so the shipment won't arrive until tomorrow. Will it last today?
