so like was he always a fox? did he always hide his ears? i’m confused….

No no he wasn't. He was a human. I think he's a yokai(fox spirit) in the last one. The purpose of the last story is to show us that they find each other in every universe. In the main story he's called a sly fox because of his twisted personality (kind but knows how to read and manipulate people if he wants too).

does anyone know where to read the novel if it has one
