Hogwarts: the Bizarre Adventures of Cell Man

I, Jin Bin, traveled to the world of reborn cells. After a lot of hard work, I finally killed King Crumble and became a new cell person. But King Chu's dying counterattack suddenly knocked me out of the world of reborn cells. When he woke up again, unknown artifacts were scattered in the corners of the world, and the strengthening scrolls were also integrated into the world. When I looked at the children in the orphanage who were talking to snakes and levitating objects with their minds, I realized that I had entered the world of Harry Potter. But... Why is Tom Riddle a girl?
