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

Tetsuya Takahashi never asked to be summoned to another world, yet that is exactly what happens to him. What should have been the start of an extraordinary adventure quickly turns into a nightmare when the kingdom realizes his summoning was never meant to happen at all. During the mandatory level assessment, Tetsuya's results reveal the worst possible outcome: a level limit of just one. Branding him "defective," the king sentences him to death for being the flawed product of a botched ritual. Rather than executing him outright, Tetsuya is cast into a monster-infested valley—a place where death comes swiftly to the weak. Left at the brink of demise after a vicious attack, he discovers his one saving grace: a unique skill known as [Absorb Corpse], which allows him to claim the abilities held by any fallen creature. The moment he uses it, the power of the corpse he defeated becomes his own, and a path forward finally opens before him. Armed with this newfound ability, Tetsuya resolves to survive in this hostile world, grow stronger with every battle, and one day exact his revenge on those who condemned him. The man dismissed as "defective" and written off at level one now begins his relentless ascent toward becoming the strongest of all.
