Delta is a Beastkin Wolf, who was saved by Shadow and adopted into the Shadow Garden as the 3rd strongest member. She's a muscle head who only respects those who have powers greater than her own. She's sadistic in nature, even having no remorse in killing her own brother who she deemed to be weak. Often she'll go overboard on missions, ending them in bloodbaths unless she is stopped. In the Seven Shadows, she attempts to act like she's not an idiot by saying "desu" at the end of some sentences
