Pretty cute. A traveling librarian and his apprentice, a half(?)/full(?) oni boy with a small horn on his head, and creatures that pop out of books make the first volume interesting.

Now, Kiichi's been ostracized for a while now do to his demon-like appearance, but after he saved Gan, the first boy to shun him, everyone loves him now??? I understand people are fickle, but y'all didn't even try to add some development there. :/

Mototaro's designed to have that aloof air of coolness,(cliche or not) I love characters like that. Kiichi's a little bit of Naruto and koolaid, but without the annoying dattebayo/believe it and prankster vibe. Hanna, the apprentice, seems like an ageless little kid. She's childish, but I don't think she has an exact age.

There's nothing groundbreaking, but I like it. I'll read the next one when I go back to the library.
