..Challenge Accepted. Welp, we've already had some sooo... What about: Light Yagami and his family. (Death Note) Sakutaro Morishige (Corpse Party) See More Alucard Hellsing. (Technically, Hellsing is his last name.) If Alucard doesn't work, then you always have Sir Intergra Van Hellsing and the rest of the Hellsing family. (From the anime Hellsing/Hellsing Ultimate) I'm sure there's many more but I'll leave it at this.
