Season 1

Ruud, who is an adventurer in the remote city of Barona, has no fighting ability and is hated by his fellow adventurers, calling him a "miasma scavenger.". He spends his days exploring the miasma labyrinth using his only skill, "state anomaly nullification," but one day he hears that a new labyrinth has been discovered. An adventurer calls out to Ruud, who is about to head towards her.

Ruud is invited by the adventurer Bayer to accompany him to the New Labyrinth as a porter for his party, the Scarlet Sword. The strategy progresses smoothly, but a powerful enemy, the Minotaur, that should not have appeared appears...!?

At the guild, Vaiell delivered the lie with a pale face. "The Minotaur killed him. Rude is dead". Fear gripped the room. But then, the doors creaked open. A heavy scent of blood and miasma flooded the hall as a shadow emerged. "Dead? That's news to me, Vaiell". It was Rude. But his eyes were no longer those of a scavenger-they were the eyes of a predator.

Rude falls into the trap of the Lizardman and finds herself in a predicament. Observing the enemy in search of a solution, he notices the alien skills hidden in an individual. At that time, I met an elf girl who was about to fall into the hands of an adventurer hunting demon.

Five years ago, the Elf girl Elysia lost everything in the labyrinth. Her party disbanded, and she was struck by a cruel "Level-Down Curse". As her strength withered away, it was Rude, the shunned adventurer, who reached out to save her.
