A young noble's illegitimate son, Ethan Dora Charasen, struggles at the prestigious Yurmus Magic School due to his complete lack of magical talent. Facing imminent expulsion and mockery from his peers, including his legitimate noble sister Arka, Ethan secretly turns to forbidden dark magic as his last resort. Through an ancient ritual, he successfully contracts with "Demi," who claims to be the Machine God from another world called Terra. Instead of traditional magic, Demi grants Ethan access to technology in the form of a handgun, along with the knowledge and skills to use it through a game-like system of Archives, Skills, and Experience Points.
