A certain Conan's Bouncing Bomb

A bouncy bomb, just like the one from the Dust Song Pot, blasted open a time tunnel connecting two worlds, bringing Klee and Nana from their original world to the completely different world of Conan.

In this world where there is almost no elemental fluctuation, there are all sorts of high-tech products: guns, ammunition, timed bombs, incredible disguise techniques, and a peculiar calendar where 365 days can be lived out as 365 days...

There are also all sorts of criminals who commit crimes using strange and unusual methods, and detectives who strive to pursue the truth, sweep away evil, and restore the light of justice.

Oh, right, there's also a group of police officers who are either somewhat incompetent but warm-hearted, or highly capable but have tragic fates.

What kind of story will the Spark Knight of the Knights of Favonius and the herb-gathering boy from Bubulu bring us here?

What kind of different opportunities will their arrival bring to this world?

...

This story is also known as "The Story of a Certain Detective Conan Kid" and "The Fantastic Adventure of the Teenage Suicide Squad".

The Black Organization's Nanaa x Detective Boys' Klee, Shinichi and Ran are the official pairings, and there will be no reverse pairings or breakups. Friendly reminder: those who dislike the Detective Boys should proceed with caution, as they will have a very, very, very large amount of screen time.
