Liebe is a devil with messy white hair, bat-like wings, ram-like horns, and a long tail with a trident tip. His body is mostly black, with red eyes crossed by dark lines. He harbors a deep hatred for other devils due to the torment he endured in the underworld and the murder of his foster mother. Despite declaring all devils scum, including himself, Asta senses a hidden compassion within him. His presence is intimidating enough to make even seasoned mages shudder.
