Amagumo from Desert Punk universe. Debt collector who takes people's souls along with their debts. The Desert Punk manga was adapted into an anime by Gonzo in 2004. Norio Wakamoto voiced Amagumo. I think the anime director found a lot of similarities between Amagumo and Alexander Anderson from Hellsing. Both are the main character's opponents, equal in strength.
Main trigger:
