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 on a reconnaissance mission inside a creepy laboratory hidden in the middle of a wraith-infested forest, Yuji's Slimes are spotted by the facility's security system—the same one that wiped out all the researchers in the decimated laboratory as part of an extreme data-leak prevention policy! With the Slimes in the crosshairs of the facility's bloodthirsty security system, will Ancient Rhino make it in time to save them?!
