The New Gate (LN) - Vol 6 Chapter 1.5: Chapter 1 Part 5

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.

【Suffer first, enjoy later】Married for three years, Aiden Fordham only met with her twice a month, each time merely fulfilling marital duties. He was indifferent to her, knowing nothing about her, until the three-year term was up. He eagerly went to find his Lover, and she turned away nonchalantly: “Aiden Fordham, let's divorce, I'll help you out.” From then on, she no longer expected anything from him, abandoned family, returned to her career, until she shone brilliantly, back at her peak, with no place for him by her side. Yet, he was repeatedly captivated by her talent, gradually attracted to her, until she completely left, only then did he learn the truth from years ago. It turned out, he had forgotten her twice, she had traveled thousands of miles to his side to resolutely protect him, just to repay a life-saving grace from the past. Regret came too late, while she had long become an unapproachable national treasure for everyone. The journey to win her back was long, only to be told “Madam, no longer wants to be the richest wife.”This time, it’s his turn to protect her, he must take drastic measures~

“Is Fate the excuse of the forsaken, is Free Will the delusion of the chosen?”Such was a question that Xavier, the Demon King, never had the chance to ask himself. As he lay defeated, awaiting his death, he wondered about the wretched life he lived.'The hero who killed me, the one who held the same ambitions as me. We both wanted good for the people, for the world. We are both two sides of the same coin, yet, fate decided that he will be the one the light will shine on.Perhaps it was me too, perhaps it was my karma for flowing the rivers of blood with my sword. But still... It was fate that squashed the humanity in me first!Damn fate, if I had one more chance, I would've lived for myself more, I wouldn't have taken this arbitrary role of being a necessary evil... This world, this game of destiny... It can burn to ashes for all I care.'As he sunk into the cold embrace of death, a certain [REDACTED] heard his dying wish with amusement and cast their die, reversing the wheel of time one last time and going all in on him on a risky gamble with the stakes of their world.
