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 system that wiped out the laboratory's researchers as part of an extreme data-leak prevention tactic! With the Slimes in the crosshairs of the facility's bloodthirsty security system, will Ancient Rhino make it in time to save them?!
*The MC is OP af but he is really chill and practical, has common sense and is not stupid. His OPness is does not have that overtly, speshul snowflake vibe. Well, the people around him treat him like he's godlike with his OPness but, with all his sturdy and chill personality, it's grounded and not all over the place. *The story is also really good. *Everything is balanced. *No unnecessary fanservice (most of manga like this have that unnecessary, sexually-toned fanservice that always makes me think that the author is compensating for a lack of *something* in their life) *Mini-arc stories that contribute to the major arc A+ *No harem A++
