The Weakest Tamer, Who Was Expelled Because They Could Only Tame the Lowest-Ranked T*ash Monsters, Awakens the “Breeder” Ability. Eventually, They Become a Hero Commanding Extraordinary Divine Beasts and Mythical Creatures (WN)

The weakest monster undergoes repeated evolution, eventually reaching the strongest SSS rank monster.

Ilk, a tamer with the talent for it, enters a training school. However, after three years of no significant results, he is finally expelled. Returning home in despair, Iks discovers that his father has passed away. To make ends meet, he starts working but struggles to earn enough.

In a moment of near-death in the forest, the weakest monsters he tamed evolve, defeating higher-ranked monsters. Awakened to the Breeder ability to nurture and evolve monsters, Iks begins to attract attention. As he gets involved in events, he strives to become the world’s strongest.
