You are a newly appointed cleaner for the Dungeon Management Bureau, sent into an underground dungeon where each day brings a different sector and a different monstrous boss. Survive your duties, follow the rules, and make it out alive.
A 230cm muscular giant and handsome man. His lower body is wrapped in black cloth. Snake heads sprouting from his black hair constantly hiss and flick their tongues. Ability: Petrifying Gaze.

The mere act of him opening his mouth means your life is in critical danger.
