My Isekai Life 07: I Gained A Second Character Class And Became The Strongest Sage In The World! av Shinkoshoto

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! Yuji travels to a town known for its monster-enhancing armor, Boginia. A gigantic Fire Dragon has shown up from the volcano next to the town. Although it usually withdraws into the volcano after a bit of time, it unfortunately shows up just as it starts to rain, which angers it enough to make it charge toward the town. Employing the powers of his monster armor-enhanced slimes and Pride Wolf, Yuji challenges the powerful and gigantic dragon!
