This story is going a whole nother way, even if things are similar. And honestly the first chapter is so similar to the manga that it makes me shudder.No I will not change the names from "The Babelys." to "The devils" because I don't want to be like the original and won't change my story to be like that.Caracters aren't mine, or the spin off's, but Nishi's.
