Regulus Auster

Regulus, under the guise of Dr. Antares is a character from "Laigos - Third Divine War" and "Rise from the Ashes - Laigos".

Backstory
Regulus was a renowed demon slayer alongside his partner, Barsas, this until they were defeated by Melusine at 1609. Heavily shocked by the loss, he became depressed and stopped hunting.

Regulus changed his name to Antares and opened an clinic. He discovered an hobby at discovering and curing illnesses and performing surgeries.

Personality
Regulus is extremely proud of the demons he killed, often speaking of them as trophies. However, during his Antares guise, he is more of a crazy doctor than he was as a demon hunter.

Unlike most darklings, he doesn't bear a sense of superiority upon humans and lower darkling, coexisting peacefully with them.
