- Description from Novelupdates

As if it wasn’t enough for me to be reincarnated as a child in the slums, I was taken to a city of crime and became a test subject. But then, when I saw the man that came to destroy the research institute, I realized that this was the world of an angst-filled reverse harem novel.

While living a relatively normal life after escaping from the institute, the heroine of the novel moved in next door. From the looks of it, I might be the heroine’s neighbor extra. Originally, the heroine was to save the unconscious and fatally wounded villain and in return, be subject to a fanatical obsession.

But, why. Why is the sub-villain collapsed in front of my house?

The sub-villain, Lakis Avalon, was the king of the underworld and the very same frightening man that I had met at the institute before.

“…”

I took a moment’s glance around then I kicked the man’s body away.

You’ve got the wrong house, Villain.

A world from another dimension suddenly appeared in the Milky Way galaxy and collided with the earth. A spatial collapse occurred, which allowed the monsters crossing over from the other side to invade various countries, and the earth fell into great calamity.

The military was powerless against the invasion because modern weapons didn't work against monsters from another world. Under the desperate situation, a god-like figure appeared and bestowed blessings upon the humans to awaken their power. From then on, the earth regained its hope, and these extraordinary people were called Realizers.

Tenku Okuihara is a five-year-old boy who dreams of becoming a Realizer to protect the world and his family. But an incident changed his life goal from a hero to a grim reaper.

The one single goal in life of the Strongest Old Sage is to subjugate the Demon King. In an epic final battle, both of them met their mutual destruction at each other’s hands.

However, the Demon King was not completely destroyed!

In order to destroy the Demon King once and for all; post-death, the Old Sage trains in the World of Gods and reincarnates as the Apostle of the Gods, Will.

In the reincarnated future, the Old Sage had become a legend and his former disciples hold the supreme authority in the world. The disciples had created an organization to oppose the Demon King and an academy to nurture the new generation of Heroes.

Thus the Apostle of the Gods, Will (8 year old), enrols into that Academy of Heroes.

This is the story of a boy on a mission to save the world through epic battles while enjoying Academy life.
