My Isekai Life GN Vol 12
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. After talking with Father Steyl, Yuji realizes there might still be a chance for him to take down a Truedrake. His journey as he tries to figure out how to do so leads him to Evildominus Island, home to a precious natural fertilizer known as Mother Earth's Tears. In order to complete his next quest, he'll have to find the guild... which ends up being on a gigantic ship! What monsters await on the notoriously fearsome island?
