Uchiha Kei thought his misfortune ended when he was thrust into the shinobi world through isekai, only to discover his system had a cruel sense of humor—it's designed to turn him into a game developer, not a legendary ninja. While the world burns with endless conflict, his mysterious power demands he create games instead. System initialization floods his mind: "Earth, year 2024 detected. Game development protocol engaged." Uchiha Kei's lips curl into a dangerous smile. If fate won't grant him peace, he'll force the world to experience his vision of torment through the very games he's forced to create. Drawing on the ruthless pride of his Uchiha heritage, he activates his ultimate weapon—a game designed to shatter everything. "Hell-mode game—activate!" What begins as a curse transforms into an unprecedented tool for power. In a world where shinobi clash and systems shape destiny, can a game developer harness his tragic circumstances to rewrite the rules of the ninja realm itself?
