Tensei shitara Slime Datta Ken, Vol. 7

the long version

Mikami's middle age hasn't gone as he planned. 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... "Milim is now a resident of Tempest, but her presence there sets off a chain of events that begins with the entrance of a rival demon lord's servants. Rimuru, as the leader of the Jura Forest Alliance, must swiftly and delicately handle this potential threat, but it won't be easy to do while managing the behavior of an all-powerful yet child-like demon lord and leading an entire nation of monsters..."--Back cover.
