Gathering Anime Crossover’s Beloved Heroines to Open a Detective Agency in Detective Conan!

[No CP + cozy everyday interactions + helping others + crossover, primarily Detective Conan + unconventional secret identities + plenty of headcanons]

After the base exploded, J was sent to Earth by the Doctor. Unfortunately, he crash-landed in Beika Town, and his body was scattered across the world. His companion System was also reduced to a remnant consciousness inside his mind.

An experimental subject with a blank mind and the codename J, he was forced to go undercover on Earth and learn how to be human.

He fought over a cat carrier, then got himself adopted by pretending to be hit by a kind old lady's car.

He thought he would live a quiet life from then on, but his benefactor passed away, leaving a will that asked him to be a good person and take her grandson's place, living his life well.

Adopted by Professor Agasa, he became best friends with young Shinichi, accidentally saved the police academy squad, took in visitors from other worlds, and founded a paranormal detective agency.

But he never expected his new identity to be connected to the Black Organization, or that his scattered limbs would start developing consciousness and causing trouble one after another.

He had no choice but to begin a journey to reclaim his secret identities, impersonating them to finish their scripts. Help! Who knew all he wanted was to be an ordinary person in Beika?
