My Isekai Life 21

In this manga adaptation of the popular web novel series, an overworked wage slave finds himself transported to a fantasy world where he quickly becomes the strongest sage in the world...thanks to the help of an army of tamed Slimes!

Yuji Sano was a normal guy working a soul-sucking nine-to-five job when he suddenly found himself transported to a fantasy world where he restarted his life as a Monster Tamer. After befriending the Slimes, Yuji is quickly able to gain a second character class, ranking up his stats and learning new skills as he encounters one surprise after another.

While enrolled at the Royal Academy, Yuji finds himself forced to participate in a school field trip from hell. After lugging a sixty-six-pound backpack around for half a day, he comes to the horrifying realization that all they have for dinner is...rocks and grass?! Faced with the prospect of slowly starving to death, Yuji realizes that he’ll have to work with his classmates if they’re to survive this diabolical walk through the woods!
