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 worker, is dragged into a game-like fantasy world after his computer offers him a transfer he accepts without thinking. There he is saddled with the Monster Tamer class, dismissed as the weakest profession — but by befriending a swarm of slimes he taps into vast magical knowledge and unlocks a second class, the Sage. The combination quietly makes Yuji one of the most powerful figures alive, even as he tries to keep his new life calm and low-key.
