That Time I Reincarnated Slime GN Vol 01 (MR)

As players of Monster Hunter and Dungeons & Dragons know, the slime is not exactly the king of the fantasy monsters. So when 37-year-old Tokyo salaryman Mikami is abruptly stabbed to death and wakes up in a world of dragons and magic, he's a little disappointed, but not exactly surprised, to find he's not a knight or a wizard. No, Mikami has become a blind, boneless slime monster, and there are chances for even a slime to become a hero!
