Overlord Tamer:I Only Tame Bosses

Lucas is given a second chance at life.

He is reincarnated as Oliver Overheart in a world where tamers and monsters rule everything, and strength decides your worth.

But just like his previous life… he fails again.

Oliver is born completely unable to tame even a single monster. In a society where everyone bonds with beasts, he’s immediately written off as useless.

A disappointment.

---

Until one day, a strange message appears before him.

**[Tame a boss monster, and the system will recognize you.]**

“…So I can only tame boss monsters?!”

---

With this strange and forbidden rule, Oliver starts his journey from absolute nobody to someone who commands disasters themselves.

Because in this world, the most dangerous monsters were never meant to be controlled.
