Lucas Carter, a stressed-out office worker, never expected to die, let alone be reincarnated into a brutal world where beasts are the key to power. Born as the heir to a lowly barony, surrounded by elves, beastkin, dragons, and demonic clans, he was supposed to be a mere pawn, nothing more than a stepping stone for the true power players.

But fate had other plans. Armed with a modern strategist’s mind and a mysterious system that grants him the ability to tame legendary beasts, Lucas quickly rises above the limitations of his birth. With the power to summon beasts, fuse them into deadly weapons, and unlock hidden skills, Lucas is no longer just surviving—he’s thriving.

By his side are his loyal companions:

Umbra, a Black Nemean Lion with indestructible fur and devastating roars that disrupt magic.

Zephyra, a playful yet fierce Baby Wind Dragon who wields the power of wind itself.

With his growing army of legendary beasts and his tactical genius, Lucas begins to build an empire. Along the way, he forms bonds with powerful women from every race, all while navigating the dangers of political intrigue, betrayal, and the constant threat of rivals who want to take everything he’s earned.

One beast at a time, Lucas will carve his name into history. But in a world where strength is everything, can his cunning and loyalty to his beasts truly make him the ultimate ruler?
