My Isekai Life – Vol 04

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 Sano’s career has gone from bleak to downright bizarre!
 
Now the world’s most powerful Sage, Yuji has joined up with an adventurer’s guild and makes quick work of wowing his new allies. And when a dragon arrives to shake the organization to its very foundations, it’s up to Yuji to lead the charge.
 But even wielding one of the strongest spells in the world, Yuji barely manages to scratch the fearsome beast! Yuji may be the strongest Sage his new world has ever known, but can the Sage best a legendary dragon?!
