Aaron, a wildlife biologist, became a military strategist right after a global war between nations began.

He never wanted to participate in the war but he had to, because he wanted to continue his studies on endangered species the moment the war was over, but to his surprise, everyone in his unit were killed, including him, and the next thing he knew, Aaron woke up in the body of a young noble having a similar name to his.

However, he also noticed he had awoken in a world different from Earth. 

In this world, demonic beasts ran rampart with only one thought in mind, causing them to feed on anyone they see, be it humans, elves or even magical beasts as well.

During his first encounter with a magical beast, Aaron awakened a system which allowed him to bond with magical beasts and to obtain terrifying abilities from these bloodcurdling magical beasts, so he used his experience as a wildlife biologist to help make it easier for him to bond with these beasts.

However, Aaron also noticed he could evolve these beasts if their loyalty towards him had reached a certain level, so he vowed in his heart to grow strong enough to protect those he cared about in this world with the hope of living a happy, peaceful life where he'll be able to focus fully on his passion as a wildlife biologist.

My Beast Evolution System

A streak of lightning rained down from the sky while icicles shot out of the ground but Aaron continued to charge toward the huge beast.

But as he did, a portion of the ice underneath his feet suddenly lifted him up like a springboard.

The electric sparks crackling in his fingertips resonated with that of his sword and his sword flew straight back to his hands.

Meanwhile, Aurora, Glimmer, Thunder and Blizzard all aimed their long ranged attacks simultaneously at the large serpent but just before the basilisk could counter their attacks, a loud deafening roar pierced through the wind and the ground underneath the serpent crumbled down, forcing the huge snake to fall into a large pit with sharp, spiky rocks that pierced into the thick skin of the serpent.

The basilisk screamed out in pain but Aaron pierced his sword into the skull of the beast as he falls into the pit with the snake.
