THAT TIME I GOT REINCARNATED AS A SLIME - OMNIBUS - VOL. 1 - INCLUDES VOLS. 1-2-3

Mikami's middle age hasn't gone as he planned: He never found a girlfriend, he got stuck in a dead-end job, and he was abruptly stabbed to death in the street at 37. So when he wakes up in a new world straight out of a fantasy RPG, he's disappointed but not exactly surprised to find that he's facing down a dragon, not as a knight or a wizard but as a blind slime demon. But there are chances for even a slime to become a hero, and maybe even build a country where the rejects and outcasts can find a place to belong...
Experience the isekai sensation that helped inspire the hit anime in a definitive, large-sized omnibus edition, including Vol. 1-3.
