6.2/10
My Isekai Life: I Gained a Second Character Class and Became the Strongest Sage in the World! is a Japanese light novel series written by Shinkoshoto and illustrated by Huuka Kazabana. It started as a web novel on Shōsetsuka ni Narō in 2017, later published by SB Creative under their GA Novel label. The story’s success led to a manga adaptation by Ponjea and an anime series produced by Revoroot, which aired from July to September 2022.
The series captures the essence of modern isekai storytelling — combining adventure, humor, and the quiet frustration of a salaryman who just wants to escape his work, only to find himself in an even busier fantasy world. What makes My Isekai Life stand out is its focus on creativity and teamwork through tamed monsters — especially its lovable slimes — making it a refreshing take on the overpowered protagonist trope.

What Is “My Isekai Life” About?
The story follows Yuji Sano, an overworked office employee who accidentally accepts a summons to another world when his computer flashes a strange message. Expecting a simple software glitch, Yuji restarts his machine—only to awaken in a fantasy world.
In this new realm, Yuji becomes a Monster Tamer, a class most adventurers dismiss as weak. However, Yuji befriends a large number of slimes, who read ancient magical books for him and instantly transfer their knowledge, granting him the Sage class as a second character specialization. Within moments, he becomes one of the most powerful beings in the world — though all he wants is to live quietly and avoid attention.
Throughout the story, Yuji faces cults, dragons, and looming calamities while building deep connections with his companions. His monsters, particularly his slimes and the loyal wolf Proudwolf, provide comic relief and heartfelt loyalty, transforming his lonely new life into a vibrant adventure.
