My Isekai Life: I Gained a Second Character Class and Became the Strongest Sage in the World!

転生賢者の異世界ライフ ～第二の職業を得て、世界最強になりました～

Yuji Sano, an overworked office employee, is summoned to another world mid-shift and handed the unglamorous class of Monster Tamer. He starts by befriending a colony of slimes near the town of Phastan, and the bond earns him a rare second class, Sage, which gives him overwhelming magic on top of his tamed monsters. Unaware of how strong he has actually become, Yuji builds a life around his slimes and the forest spirit Dryad while settling into his new world.
