Rise of the God of Kuoh
He died a nobody. He woke up in a void, played God at chess, and won.
Now he holds the crown, the throne, and every power the Almighty ever wielded, and God was only a fraction of the being those powers came from. All of it is sealed inside the most mortal, most laughable body he could have landed in: Issei Hyoudou, the school's number-one pervert, the boy destined to be killed on a first date, revived as a devil, and dragged through a war he never chose.
Just his luck.
But he isn't going to play along. Raynare thinks she's stalking a harmless idiot with a dangerous Sacred Gear. Rias Gremory thinks she's about to acquire a future Pawn. Heaven, Hell, and the Fallen all think they know how this story ends. None of them realize the boy on that bridge has already read the script and is laughing at it.
He doesn't want to be a devil's servant. He wants to be the one setting the board.
With two perverted best friends who now call him god, a dragon emperor who just agreed to serve him, and the power to rewrite the laws of the Sacred Gear System itself, he's building something the supernatural world has never seen: an army of his own pawns, forged and loyal to no Satan, no angel, and no Governor.
The factions want a war. He wants the whole board.
The question isn't whether he'll change the future of this pathetic world. It's whether anyone will be left standing when he's done rewriting it.
