Genkai Level 1 kara no Nariagari: Saijaku Level no Ore ga Isekai Saikyou ni Naru made

A man named Tetsuya Takahashi is unexpectedly summoned to a different world. Due to an error in the summoning process, he undergoes a level assessment and is assigned the lowest possible [level limit], lv.1. The king labels him "defective" and sentences him to death. Without consent, Tetsuya is cast into a monster-infested valley where he is nearly killed. In desperation, he activates his unique ability [Absorb Corpse], which allows him to take on the skills of the creature that attacked him. Determined to survive, he resolves to grow stronger and seek retribution against those responsible for his summoning. The man once called "weak" and "defective" begins his path toward becoming the strongest.
