Slime wa Saikyou Taru Kanousei wo Himeteiru: 2-kaime no Jinsei, Chanto Slime to Mukiaimasu @comic

In a world where an individual's destiny is entirely dictated by the magical beasts they contract with, Zeke was dealt the worst possible hand. Bound to a slime—widely regarded as the most useless creature in existence—he endured a lifetime of poverty and relentless ridicule. He spent his days scraping by as a lowly cleaner in the slums, burdened by regret and the scorn of everyone around him, until he finally met a bleak and despairing end. However, death was not the conclusion. Zeke suddenly awakens to find himself thrust back into his childhood, granted an impossible second chance at life. Armed with the knowledge of his past failures, Zeke refuses to repeat them. His primary goal is to secure a better future for Fios, the slime who stood as his only true companion during his previous life. Rather than accepting mediocrity, he sets his sights on an ambitious transformation: rising from a destitute slum worker to the leader of a grand merchant association. To achieve this, he plans to fully harness his partner's overlooked ability to dissolve absolutely anything. As their journey unfolds, it becomes apparent that Fios harbors even deeper, hidden potential. Together, this once-weakest duo embarks on a miraculous second life, determined to dissolve the darkness of their world.
