After Rebirth, I Married the Great Demon King - Chapter 39: Take Good Care of Yourself

So here's the pitch: I got reincarnated with Mangekyo Sharingan.Sounds overpowered, right? Instant win button?Except I can barely keep it active for thirty seconds without feeling like my brain's being microwaved. My chakra reserves are pathetic. My combat experience is zero. And the system that gave me these powers took one look at my situation and said “good luck” before fucking off into hibernation.Oh, and the Hero Killer—the guy who murders heroes for not being “worthy”—just decided my mom wasn't good enough. She'll never walk again.I know when he'll strike next. I know where. I've got exactly four weeks to train.Four weeks to go from “can't throw a punch without tripping” to “can survive a fight with a serial killer.”The smart move? Stay out of it. Let the pro heroes handle it.But I'm fifteen, angry, and apparently making life decisions with the wisdom of a shounen protagonist.At least I'm in General Studies. Low expectations.What does being a hero have to do with revenge anyway?

An Extra is a minor background character with little to no influence on the main story. Their purpose is to fill out scenes and represent the larger world in which the story takes place.Yet,One Extra defied its existence. One Extra destroyed the story.********Luke, an editor, was transmigrated into the story with one goal:“Kill The Extra.”

“Your stats are lower than that of your average person.”

The weakest by a mile among the otherworldlers of class 1-A, Takatsuki Makoto.

The Heroes and Sages who had cheat skills in his class had went off, and the base set lifespan is 10 years?

The Great Demon Lord is going to revive soon?

I am a Mage Apprentice?

Isn’t the balance way too bad? This damn Isekai is a tr*sh game!

“Want to be my believer?”, the Goddess that told me this has zero believers!

Aah, this is bad…I don’t think I can clear this. The Goddess with zero believers is an incredible beauty, and she is telling me she is imprisoned somewhere and is waiting to be saved. My last and hardest mission is to save the Goddess.

Clearing this Isekai that only has adversities, the story of the weakest mage.

I had nothing left to live for.No family. No friends. No future.Just a shattered soul wandering through a world that had already taken everything.Then I died.And that’s when everything changed.I woke in a world of light. A void between realms. A place where gods whisper and broken souls wait to be judged. There, I met Ashen Crimson—a man who had once been worshipped, then feared, and finally cursed by the very gods he had defied. A tyrant who had destroyed his own world.But now, he’s offering me something terrifying:His life. His past. His power. His chance to make things right.The catch?The world of Zerawell is fractured.Ashen’s name is soaked in blood.His fate is sealed—exile, ruin, and eternal hatred.And now, it’s my name.Because I’ve been reborn as Ashen Crimson, heir to a house that both reveres and reviles me. A noble with dormant shadow magic, a shattered reputation, and a cursed destiny I never asked for.But I’ve lived a life of pain. I’ve walked alone through hell already.And I won’t follow his footsteps into madness.With a divine system familiar in my soul, a second chance burning in my chest, and the memories of a monster as my burden—I will rewrite this fate.Let them call me villain, disgrace, or traitor.I didn’t choose this story.But I’ll finish it.Even if it kills me.
