He traveled to the Harry Potter world and became the last bloodline of the Prince family, a blood relative of Snape!

Alan Prince vowed never to be a good person in his life, but incidentally saved Snape from his tragic fate.

Some people say he's just a child with a bad temper.

Some people say he is a dark demon king who wreaks havoc in the region.

But many more people see him as the salvation of an ordinary wizarding family and a great man who led the magical world forward.

P.S.: What kind of normal person could a child raised by Snape be?! (Snape: He's slandering me!!!!)

The synopsis is weak, so I'll move the main text. There's a decent Harry Potter fanfiction as a base, so feel free to use it.
