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 the wraith infested forest, Yuji's Slimes are spotted by the facility's security system. With the poor Slimes caught in the cross-hairs of the bloodthirsty system, programmed to protect the organization at any cost, will Ancient Rhino and Yuji make it in time to save them?!
