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.

"Thank you, Your Highness, and sorry for bothering you with something like this," Aaron said, expressing his gratitude, but Aurora simply replied with a smile and a nod before heading towards the greenhouse.

Meanwhile, Glimmer noticed the sad look on Luna's face as she stared at Aaron's back.

Aaron was currently standing in front of Luna, but since he hadn't said anything since Aurora agreed to help her, Luna was worried that he might still be mad at her even if he didn't want to admit that he was.

However, Glimmer had finally gotten the gist of what happened and she didn't like the tense atmosphere between Aaron and Luna, so she walked closer to Aaron, rubbing and nuzzling her nose against his leg with the hope that it would brighten up his mood.

Seeing this, Aaron smiled and asked. "Glimmer, what do you think? Should I forgive my sister for bothering the princess with the mess she made?"
