Akumako makes up a villainous trio with V-Darn and V-Sion, the former who she calles her "master". She is a tiny devil girl who is not at all shy about boisterously expressing her sadistic tendencies and lust for blood, pain, suffering and death. She could be considered the only villain in the series that is devoid of sympathetic or empathetic qualities, though she is very much presented as a comic relief character. Part of the joy she receives for violence stems from the fact that she is a devourer of souls, though this act is never presented in the episodes. Akumako is last seen stranded on an island with a defeated V-Darn and V-Sion; her fate left unknown.
