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～ , Tensei Kenjya no Isekai Life
Whether he is at work or at home, office worker Yuji Sano spends all his time on the job. So when his personal computer flashes a message saying he has been summoned to another world, Yuji restarts the machine, only to find he has accidentally accepted the summons. Now in a fantasy world far from paperwork and computers, Yuji has just one thing on his mind: waking up from what he believes is a dream and getting back to the pile of work he left behind. But this other world has other plans for Yuji, who soon discovers that his Monster Tamer character class lets him befriend slimes. And thanks to their numbers, those slimes help him absorb so much magical knowledge that he gains a second character class in the blink of an eye. How will Yuji use his power now that he is the greatest sage the realm has ever known? And what about all that paperwork?
