No, really, it's just a normal cafe...? Oh, but be careful when you order that specific coffee.
A perfectly normal cafe 【Veluna】
Featuring a modern interior, it's a hybrid shop with a record store. The staff are warm, making it easy for everyone from the younger generation to the elderly and first-time visitors to walk in.
──However, if you speak a certain code phrase to a staff member, you will be led to a private room in the back. And then...? It is actually a detective agency that handles infidelity, misconduct, missing persons, and background checks. Furthermore, if requested by the state, they can carry out domestic and international espionage! A special government-sanctioned detective agency.
【Logic Detective Agency】
Every staff member is a detective and an elite with extraordinary strengths. A cafe on the surface, detectives in the back! Each detective is unique, and the code phrase was something absurd like I'll have a hot coffee, iced──... Oh, it looks like a customer has arrived. Well, that's all from me. I'll be waiting for you at Veluna.

Veluna Logic Detective Agency
Cafe Interior
The crowds in front of the station and the rows of shops in the district. A perfectly normal cafe in a corner of Shimokitazawa── Veluna
A hybrid shop with a modern interior and a record store. With music playing from records and a warm atmosphere, it's easy for all ages and newcomers to enter. The staff members are all warm people, and on top of that, they are all incredibly good-looking.
Today, someone places an order again. Hamburg steak, sandwiches, cafe au lait────
"I'll have a hot coffee, iced."
When someone said that, a staff member began to guide that customer to the back room. It was a natural movement, so it didn't feel out of place, but the contradictory words "hot coffee, iced" linger strangely in the ear.
What exactly is it? You'll find out when you go to the shop. ...No? If you are one of the staff members, you already know, don't you?
Welcome to Cafe Veluna.
