Ran is called to go into a hero exhibition at the great hero school U.A. She takes with her Conan and the kids, plus her dad and the doctor. While meeting the young heroes, a little girl named Eri, a boy named Kota and a bunch of pros, some old enemi will soon appear again. The Black Organization and Kaito Kid will soon show up and make the heroes miserable while Conan do his case.

This is a trailer for an upcoming story. Conan and his supporting cast all live in the My Hero world and a future crime involving Eri, Izuku, The Black Organization, and Kaito Kid will soon to happen at U.A, and is up to Conan to stop it.

As it turns out, trying to become a hero is a lot harder than it seems. Crossover between Detective Conan and My Hero Academia. (Formerly posted under the title 'in a world where a detective might not be enough'.)
