Here's the game. There are four schools for training folks with various abilities and paradigms.
The Leaf Village Ninja Academy
My Hero Academia
Hogwarts
Brakebills
We have as students:
Naruto
Izuku Midoriya
Harry Potter
Quentin
Assume age is no problem. None have graduated but are solid students with abilities. They transfer to each of the school with their abilities from their home institution. They wear clothing appropriate to the new school and that is not a handicap. Harry can take his wand.
How do they do and progress?
