Daemon is a leader of a pack of 200 dogs.

Ginga Densetsu Weed

11 years ago, Daemon challenged Gin to a fight, because he had killed one of Gin's messengers. Gin only brought Tesshin with him to face Daemon's pack.

Daemon took this as an insult and charged at Gin. Gin dodged the Pitbull's bites, threw him in the air and he landed heavily on the ground. The blow killed Daemon instantly.

This fight was told in a flashback by Jerome as he had witnessed the fight when he was 2 years old.
