Zeoticus Gremory

Zeoticus Gremory is a character from High School DxD. He is the current head of the Gremory Clan (one of the 72 Pillars of pure-blooded devils) and the father of Rias Gremory and Sirzechs Lucifer (the current Satan Lucifer). He is also the husband of Venelana Gremory and grandfather to Millicas Gremory.

He appears as a handsome, middle-aged man with long crimson hair (tied in a loose ponytail), bright blue eyes, and a short red beard. Known for his extremely kind and affectionate personality (a trait of the Gremory Clan), he is generally supportive of his family and even gets along well with Issei Hyoudou's parents, casually referring to Issei as "son" at times. He plays a supporting role in the series, mainly appearing in family-related scenes.
