Doom Breaker Volume 1 by Blue-Deep

Zephyr is the last human fighting evil in a world abandoned by the gods. After a five-year war against humans and demons, Zephyr is slain by Tartarus, the Demon Lord. In the aftermath, much of humankind was either slaughtered or captured as hosts for demons. When all seems lost, Zephyr is abruptly reincarnated, much to the sinister amusement of the gods, to save humanity and avenge those he loves.

With his newfound second life, Zephyr is flung ten years into the past without his physical strength, starting at square one as a temple slave. Marked with a brand keeping him in servitude, he must navigate his new reality and regain his former powers. Some gods are still rooting for Zephyr's success and offer him perks as he continues his quest, leading to the ultimate battle against the god of destruction, Tartarus, once more. Can Zephyr finally have his revenge and save the woman heloves, or is he doomed to repeat the past?
