Tokyo: My Crime-Solving Group Is Full of Great Detectives

Higashino Jun transmigrates into a student at the Tokyo Police Academy. He originally just wanted to slack off, coast through life, and be a tax-funded freeloader.

But after joining a chat group called "I'm a Famous Detective," he realizes there's something off about the members.

Every member is a serious chuunibyou. They pretend to be Holmes, Poirot, Di Renjie, and Conan, and spend every day studying methods of murder.

Then Holmes sends him a special piece of equipment through a group red packet.

Only then does Higashino Jun discover that the famous detectives in the group are all real!
