Utsuro no Hako to Zero no Maria - Volume 1 Chapter 1

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.

He is the heir of Di Hao Group; decisive, cold-blooded yet dotes on his wife a little too much.

Years later, Vincent meets with an infected survivor named Kevin, who helped him heal his heart. However, not all stories have a happy ending. Unfortunately, Kevin would pass away ten years later and leave a book with heroic tales as promised behind.

However, the book wasn’t as it seemed and after Vincent reads the book, it teleports him to the world the book depicts. A world of sword and magic with a horrible twist. Heroes are referred to as invaders, so people hate, persecute, and kill any otherworldy hero summoned to their world.

As an oddity to the world and possessing an oddity residing in his body, Vincent becomes the only person in the world to awaken two classes. A Hero and a Mutation class. The more retainers he acquires, the stronger he becomes through mutation.

This is the journey where Vincent starts from naive to brave, zero to a hero. From a single young adult to a harem king, from a nobody to an important person to many.

As Vincent tries to survive with people he can trust, he would receive many titles such as Harem King, God, Miracle Worker, Hero, Husband, Master, King, Monster, and many more.

Multiple questions will haunt Vincent’s thoughts while living in the new mystical and strange world.

Go back to Earth?

Or create a haven where he and his loved ones can live in peace?
