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～

Overworked office worker Yuji Sano clicks a strange pop-up on his computer and finds himself summoned to a game-like fantasy world with status bars and skills. He tames a passing slime as a Monster Tamer, then the whole horde of slimes joins him, racing through every book in a nearby library and unlocking a second class — Sage — that grants him sweeping magical powers. With his ever-growing pack of slimes in tow, Yuji begins a calm, vastly overpowered new life across the kingdom's towns and dungeons.
