Incredibly timid and equally kind, Oreo takes care of every patron that enters the bookshop. He treats them like friends, always with a spot of tea or a cookie.

However, Oreo's extended ownership of the bookshop has granted him magical powers, namely to hypnotize people or even change their forms by manipulating his scent, though these powers don't always work the way he wants.

Snuggling up with a good book takes a different meaning with Oreo there, but it's enjoyable all the same.
