What if Conan swallowed APTX4869 and not only shrank, but also suffered a magical outburst?
The magical outburst accidentally sent him into a time-space rift, transporting him to a crossover world combining the Sherlock TV series and the Harry Potter and Hogwarts series.
As a Sherlock Holmes fan, Conan transmigrates into the modern world of Sherlock and meets Holmes and Watson. (A fan meets another version of their idol, lol.)
Sherlock Holmes: "John, you actually brought home a kid who's practically screaming trouble from head to toe!"
John Watson: "Sherlock, he's just a child, and he's injured and unconscious on our doorstep. How could I just leave him to die?"
Sherlock Holmes and John Watson adopt a boy named Edogawa Conan. He's not only a visitor from another universe, but also a young wizard.
That's right, a few years later, a Hogwarts letter arrives at Baker Street, inviting Conan to enroll.
When Hogwarts welcomes the Grim Reaper Elementary School Student (crossed out) and the Holmes family, mysterious creatures in the Forbidden Forest, such as Acromantulas, keep turning up dead. (The people are fine; it's mainly the animals that suffer.) Voldemort and the Death Eaters have a terrible time of it.
[Interview]
Reporter: "Conan, what do you think of Sherlock Holmes?"
"..."
Shinichi, who used to rattle on endlessly whenever his idol came up, has a complicated expression. That's because the Sherlock Holmes in the original stories by Conan Doyle is quite different from Sherlock Holmes in the TV series.
"Which Sherlock Holmes are you talking about?"
Under the watchful gaze of the guardian behind him, the reporter promptly shut up.
[Family Profile] (Conan version)
An extremely confident genius detective with a sharp tongue + a gentle man who is a devoted Sherlock fan and a renowned author + an elementary school student who's another die-hard Sherlock fan, reading Sherlock Holmes and aspiring to be just like him.
Anderson and the others: "Oh, God, look at this family."
Moriarty: "When did the great detective get a son? That was fast."
(He gives the bristling doctor a meaningful look.)
