Insanely-Talented Player - Chapter 167

The previous lords have committed as many atrocities as possible to fill their bellies. I, the only daughter of that house, had discovered that my servant and lover was a spy.

And as the people wanted, my life ended with my execution.

However, with the memory of getting beheaded intact, I began a new life. I was planning to shoulder the sins of my past life and become a nun, but by some trick of fate, I came to work as a maid for the current lord.

Under my former lover, whose name, age and even hair colour were all lies.

After her rebirth, she stared at her drop-dead gorgeous husband and suspected that she must have struck her head hard at the door for demanding a divorce time and time again!

In her previous life, she was blinded and murdered by her blood relatives. Now that she was reborn, she vowed to hold on to this thick thigh of her president husband, ravage her enemies, tear down that white lotus and regain her happiness.

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.
