Maylgeiz is the second in command of Naru Holder's dungeon. She was once a legendary magical bikini armor heroine, known as Brave Buster Maylgeiz, but had joined forces with the dungeon denizens, becoming a sort of gazer monstergirl. The human kingdoms would claim that she was "cursed" or "corrupted," but she came of her own volition, and would regard it more of a matter of perspective.
Her story is robust, both in past adventures, and current daily job, providing different challenges and life lessons along the way. Here's some art of both her Brave Buster heroine days, and her monstergirl dungeon office life.
