In this manga adaptation of the popular web novel series, an overworked wage slave finds himself transported to a fantasy world where he quickly becomes the strongest sage in the world...thanks to the help of an army of tamed Slimes! While on a mission to destroy every single delicious Silvervine in the Fudorua region, Yuji and the Slimes stumble on a deserted library in plain view. Inside, they find a plethora of books on enhancing various abilities, which Yuji quickly puts to the test by attempting to boost the elemental power of his Slimes. Wanting to gather more information in preparation for taking down a Truedrake, Yuki finds himself at the nearby town of Luisia where he decides to take on a scouting quest to ultimately slay a fabled Luisia Rhino.
