Shiina Kazuya dies shielding strangers from an attacker and wakes up in another world as Cain von Silford, the three-year-old third son of a noble house. On his fifth birthday the world's gods name him their apostle and hand him strength, magic and intellect built to reshape the world, and Cain has to grow up fast, hiding just how far beyond human his gifts really go while navigating a court full of aristocrats, gods and young ladies who all want something from him.
