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.

Luo Qiu became the boss of a ‘club’ by chance.

It was a weird club that sold strange items and with a servant girl that had 300 years of working experience. Countless people with dreams, hopes and ambitions came to the club to exchange anything precious they own for what they want. They would offer their lifespan, items, and even their soul. Every successful trade would increase Luo Qiu’s lifespan by a little.

“Tribute successful, your lifespan has increased by 99 years.”

As thus, Luo Qiu began his endless life as the club’s boss.
