That Time I Got Reincarnated As A Slime 1

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 not a knight or a wizard but a blind slime demon. But there are chances for even a slime to become a hero.
