Leian: a Different Campus Life

I'm Looking for Books on the Concave and Convex World, as Many as I Can Get. of Course, It's Best to Have Leian

Is There Really Nothing Good About Lei Anwen?

I would like to read a book similar to "Why do you need to dress up as a boy when you wear a book?"

Asking for Leian's Book

I want to read a book similar to "Vampire Forbidden Zone, Leian". Are there any books like that by Leian? It can be sweet or cruel. If possible, it's better to be a little cruel. Please!
