I thought I had seen bad endings before—but nothing prepared me for the garbage conclusion of The Hero’s Path.Years of investment, countless struggles, and for what? The protagonist failed. The villain won. Everyone else? Dead. Furious, I sent a message to the author, only to get a chilling response:[Do you think you could do better?]Before I could even blink, my phone exploded in a blinding light, and the next thing I knew—I was waking up in a completely different body.Now, I’m Merlin Everhart, a fourteen-year-old with a 12-star talent, the kind of gift only the strongest should have.But here’s the problem: I have no idea who I am supposed to be.With nothing but a system and a first-day-of-school alarm ringing in my ears, I’m thrown into the world of The Hero’s Path.Am I just another side character in a world that already ended once?…Either way, I refuse to let this story beat me too.

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.
