E-rank adventurer Lude was born with a unique skill. However, it was a questionable ability called [Nullify Status Abnormality]. To overcome his current situation, he dives into a new labyrinth but encounters a B-rank Minotaur. Abandoned by his teammates, he falls into the abyss. He was injured, his supplies were depleted, and the only thing he could eat was the Minotaur in front of him. However, in this world, eating monsters was taboo, and eating them causes physical abnormalities, eventually turning the perpetrator into a monster. While there was a large risk, Lude believed in his unique skill and ate the monster to survive. Then, Lude’s unique skill was activated, and the monsterification was effectively nullified. He was even able to acquire monster skills. Lude, who understood the true use of [Nullify Status Abnormality], earned skills by earnestly consuming monsters. This is the upstart adventure story of Lude, who dreams of becoming an S-rank adventurer.
