Nidome no Yuusha - Chapter 126 - Minnalis wails

When Su Yaya awakened, she found herself in a novel world as the CEO’s Substitute Wife–-a mere cannon fodder. Knowing that divorce and a tragic ending was awaiting her once her look-alike, the President’s first love returns, Su Yaya only trusted one thing: Money.

Time travelling from the majestic era after the Recuperation of Reiki, he became Kimura Kazuki, a 16-year-old high school student in Japan, one year before the Reiki Recuperation.

Tentatively, he set out to hone himself to the bone, burning candles at both ends to stockpile resources in preparation for the imminent Recuperation of Reiki. His goal was to be many steps ahead of all humanity when the time comes.

However, it seemed like fate had decided to play a cruel trick on him.

One year later, the Recuperation of Reiki… did not happen as expected.

When I opened my eyes, I wasn’t just in another world—I was in another body.Specifically, the cursed husk of Dominic Nocturne von Morningstar—exiled demon prince, son of a murdered Demon King and a sleeping Demon Queen, and the world’s most powerless noble.Why? Because as a child, Dominic was betrothed to the Seven Daughters of the Seven Satans—supposedly weak, discarded girls. To seal the deal, a forbidden contract drained him of every drop of talent and sin affinity... and gave it all to them.Now, each girl commands a monstrous Sin—Wrath, Greed, Lust, Gluttony, Sloth, Envy, and Pride.And every one of them is dangerously obsessed with me.But what they don’t know is:I’m not the original Dominic.And I have a secret they must never learn—A cheat-like system has awakened inside me: The Lucifer System.A path to reclaiming my powers, rewriting fate... and maybe even dethroning the Seven Satans themselves.That is—if I can survive my psycho wives, hellish quests, and a world that wants me erased.

Once again, Ye Zhen Zhen had lost her memories. When she opened her eyes once more, arranged in front of her were——

1. A Maternal Grandfather, the Murdered Victim

2. A Large Inheritance

3. A Deeply in Love Fiancé

4. An Overbearing Maternal Uncle and his Wife

5. A Docile Servant

6. The Aloof, Cold, Abstinent Doctor in Charge of the Case

7. A Seemingly Difficult Police Officer

Reincarnated as a detective, Ye Zhen Zhen stared dubiously at them all. Who was the murderer? Was it her? It…?

Only one was the real murderer, but there was far more than just one culprit.
