It's a small wolf-like beast. They tend to prowl around in packs at night, howling at the moon. They're often trained by Signers who like to think of themselves as a cool loner type... despite the fact that these beasts live in close packs in the wild rather than alone.In-game description

Lupups cannot be found in the wild. They are not used by any enemy signers, except for those participating in the Random Tournament.
