In the face of a beautiful blonde girl, Alex, a mysterious sense of deja vu washes over him… This looks just like the prologue of the game “Resis-Noah” in my dreams! After realizing that he is the final boss of this world, he decides to fake his death so he can enjoy a new life. With his cheats in hand, the new dark hero strives for a life of freedom!!

Born as the Thirteenth Prince, Noah was originally in a position removed from the imperial succession, so he freely passed his time in the fief granted to him.

Noah, being the strongest despite living freely, overwhelmed the other princes and eventually became the Emperor with the most power in the world.

Live a slow life.

And so Roland, with his ability to blend perfectly into the crowd and the disguised demon king Leila at his side, decides to live a peaceful life.
