My Isekai Life 19

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. Yuji learns of a book containing important information regarding the evil organization known as the Laboratory. Unfortunately, the book is locked up within the Royal Academy, meaning the only way to access it is by...enrolling as a student?! Faced with his dreaded nemesis, the entrance exam, will his skills be good enough to let him pass?
