Lucas was given a second chance at life.

Reincarnated as Oliver Overheart, he discovered a world ruled by tamers and monsters, where strength meant everything.

But just like his previous life…

he failed again.

Born without the ability to tame even a single monster, Oliver was labeled a disappointment.

Until a message appeared.

[Tame the boss monster, and the system will approve you.]

“…I can only tame boss monsters?!”

With this forbidden power, Oliver begins his rise, from a nobody to a being who commands calamities.

Because in this world…

The strongest monsters were never meant to be controlled.
