World's Strongest Became the Game's Weakest Villain - Chapter 465 - 460: STRONGEST - End (LAST CHAPTER)

The world was once at war with 10 alternate worlds. This was known as the Concept War and our world won 60 years ago. All of this was concealed so no normal people are aware of this fact in the current time.

After the death of his grandfather, the high-school student Sayama Mikoto is suddenly summoned by the giant corporation IAI. He learns this world is headed for destruction due to the acceleration of the Minus Concepts. To prevent this, negotiations must be undertaken with the survivors of the other parallel worlds so their 10 concepts can be released.

And so Sayama is caught up in the final battle to clean up after the Concept War which left behind so much enmity.

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

Lacking a pocket dimension, lacking a power, lacking a thigh to hug onto and the three life advantages (money, power, and looks), he had been cautiously living in the apocalypse for ten years, getting closer to falling inside the zombie’s mouths. But unexpectedly, he had the terrible luck, to be caught in a fight between two gangs and die, it really left people feeling disappointed.

But when he opened his eyes, he had returned to a decade ago, three months before the apocalypse!

Like before he still lacked an ability, an ordinary person without a pocket dimension, but he did have ten full years of experience living in the apocalypse! Even if he didn’t fight zombies, didn’t hunt monsters, he could still live a carefree farming life in the safe zone.

Find a safe house, utilise all kinds of skills from his previous life to farm in exchange for meat, and if possible, find a person to peacefully spend the rest of his life with; ordinary people had their own ordinary little pieces of happiness.

Originally believing he had picked up a beauty he returned home to prepare a golden house, but on the contrary he was the one being pushed down……someone once said, whether it is people or matters, by no means can you only look at the surface!
