Boku no Nakama wa Isekai Saikyo Undead

Yuma was an ordinary college student until he was abruptly summoned to another world. Like many who find themselves in such a situation, he was granted extraordinary cheat abilities and naively anticipated an exciting new life. Instead, his arrival led to immediate capture and unimaginable cruelty. Researchers fascinated by his potential subjected him to relentless mutilation, treating him as nothing more than a living experiment. The true horror of Yuma's predicament lay in his specific power: absolute immortality. No matter how much agony he endured or how desperately he pleaded for release, his body continuously regenerated, denying him even the mercy of death. Trapped in a cycle of intense pain and forced healing, he was reduced to a mere specimen within the confines of a cold research facility. His bleak existence finally began to shift when he encountered Eva, a beautiful young woman who was also being held captive in the same facility. Her presence offered Yuma his first glimpse of hope in a world that had shown him only suffering, marking the beginning of a change in his tragic fate.
