Asmo is a short, chubby demon with dark black skin, small demon wings, small nubby horns, and a long demon tail. He has short hair, and his eyes are almost always shut (but he can still see). He wears a bright pink jacket off his shoulders and dull pink pants, along with white-and-pink shoes with a heart designs on each side. He wears a binder at all times when in public and commonly refuses to take it off (even when it hurts).
