Hailing from a prestigious tamer family renowned for taming and excelling with high-ranking monsters, the protagonist could only control goblins (who are actually ogre-kin). Kicked out of their family home, they became an adventurer but were expelled from every party they joined.

While working to improve their own abilities and foster the growth of their tamed monsters, the protagonist remains unaware that they can tame not just goblins, but all ogre-kin and related species.

This work centers on a protagonist who, mistaken as a failure by those around them, eventually realizes their misconception, takes revenge on former party members and family, and delivers a satisfying comeuppance.
