My Isekai Life: I Gained a Second Character Class and Became the Strongest Sage in the World!

Yuji arrives at the guild of Phastan. He gathers that more than 10,000 monsters have gone berserk and are charging at the city. Using the Dragon Bone in his possession to recreate flame, Yuji proposes a shocking plan to eliminate the monsters.

After registering as an adventurer in Kilia, Yuji accepts a quest and joins a party. Since Yuji is a Tamer, his role is to scout out the enemies. As Yuji and his party venture into a forest, one of them goes missing at night.

Yuji and his party continue to look for the Earth Dragon. As they arrive at Delight Canyon, the Earth Dragon appears! Yuji finds a way to show Tina and Lisa how strong he is while defeating the Earth Dragon.

To defeat the dragon found in Delight Forest, a Subjugation Squad is formed for a final showdown the following morning. Yuji stays put in the Subjugation Squad. He goes to the forest at night using his Slimes and Proud Wolf.

Ricaardo is a warm and cozy town. 10 days ago, it was attacked by a winter storm. A thick layer of snow covers the town and the restaurant Yuji visits doesn't have enough firewood to cook. To enjoy a scrumptious meal, Yuji decides to help the restaurant gather firewood.

There is an underground entrance in the forest. Several giant machines and suspicious men are found in the underground area. After Yuji returns to the surface, he finds Messias, a hidden village for the Blue Moon of Salvation cultists. Upon learning the cult's evil agenda...

Yuji is now traveling to Boginia, a place famous for its armor. He plans to visit an expert blacksmith, Geigel. However, he runs into a pitiful individual whom he has never met before on his way.

To forge armors that can withstand the power of Slimes, Blue Ember Dragon orbs are needed. Yuji heads to the Adventurer's Guild immediately to take on the quest to slay dragons. But it seems like magic doesn't work on dragons...

A volcano erupts and a Fire Dragon appears! As long as it's not drenched, it will remain docile. Unfortunately, it starts to rain. Can Yuji save the town from the rampaging Fire Dragon?

Yuji reunites with Priest Steyl in Ordarion. Steyl recounts to Yuji his story with a man called Walter and God's prophesy. According to the prophesy, Yuji will meet Walter one day.

Yuji finally meets Walter. Walter consumes the Dragon's Grace before everyone and transforms. Whenever Walter is hurt, he can recover by absorbing the cultists. How can Yuji defeat Walter?

After Walter suffers a defeat by Yuji, he sacrifices himself to resurrect the mythical Sage. To save the world from the never-ending crisis, the Sage plans to destroy the world. He uses his power and turns every monster berserk...
