Guy in Harry Potter with Quirk Overhaul

After death, the guy wakes up in the world of Harry Potter. Please keep in mind that I am writing simply because I want to and am using a translator. I am not a master and I think that there will be many mistakes or inconsistencies and even crazy moments in this story. You can read if you want, but don't expect anything good. Harry Potter does not belong to me, nor do any other characters or references.
