Andras.
Chosen by Demon King Solomon to become the 63rd dungeon's master, she was originally a mutant harpy.
Black wings.
Born with black color from birth, the harpy was abandoned by her kind, and somehow caught Demon King Solomon's eye to transform into a new being with a humanoid body.
She received the name 'Andras' from Solomon, and Andras built her dungeon based on her characteristics different from harpies.
"I'll build a dungeon with only my offspring."
Her grand plan collapsed the moment she bore her first child.
Senior demon [Halphas], who she believed without doubt would help her, cursed her while ejaculating inside Andras, and Andras received both the Demon King's blessing and Halphas's curse simultaneously.
Bird-brain humans.
Originally close to a birdman, Andras bore children with heads exactly resembling Halphas due to his curse. Though unfortunate, Andras had no choice but to keep bearing such children.
