In the 30th century, Tyler Rustel is an eccentric and visionary genius, renowned as a brilliant inventor. His life, however, comes to an abrupt end when a small experimental nuclear reactor explodes in a series of unforeseen events. Yet, death is not the end for Tyler. He awakens in a body that feels both familiar and foreign—a parallel version of himself in a completely different universe.This is not a world of technological progress or orderly civilization. Here, twisted gods roam the cosmos, shaping realities according to their cruel whims. The moral laws that governed his previous world do not exist. This is a magical universe, one marked by brutal betrayals, interdimensional wars, and endless massacres. The balance between the forces that rule this cosmos is fragile, and Tyler finds himself at the center of schemes involving powerful entities and boundless ambitions.However, Tyler is no longer an ordinary man. Upon awakening in this new world, he discovers that a fragment of his technology has survived with him: an advanced artificial intelligence system capable of analyzing, adapting, and enhancing anything, provided it has the necessary data. From magical weapons and arcane spells to alchemical techniques and enchanted jewelry, everything can be optimized under his supervision.Armed with this technological advantage in a universe dominated by magic, Tyler quickly realizes the potential of his unique position. While others struggle to survive, he schemes to conquer. Driven by his sharp intellect and a questionable sense of morality, Tyler embarks on a ruthless campaign to achieve magical supremacy and subjugate all worlds around him. He seeks neither redemption nor alliances. His ambition is clear: to rule everything and everyone as a tyrant, to amass an immense harem of women, and to father one million children to establish his legacy across all realms.

Thanks to the Goddess, he was reincarnated into nobility!　That should have been great―― but the skill he got, 【Toxin Decomposition EX】 was simply too plain, and he was made fun of everyday at home……

“I'll do it. I'll do anything you want”Raiden clicked his tongue in a disapproving tone then raised Hiro's head once more.“That's not what I want to hear, Hiro” He said. “I want to hear you say it with your lips. I want to hear you acknowledge what you will be to me and your status from this day henceforth.”He stared deep into Hiro's beautiful brown eyes as he spoke; “Say that from this very second, you belong to me. Your body, your soul, your mind, every part of you belongs to me. You will be my pet and remain by my side. You will do whatever I ask you to do. Tell me that I own you, Hiro.”Raiden's voice was frighteningly deep and Hiro felt shivers run down his spine. There was nothing he could see but Raiden's smokey grey eyes, his handsome face and that devilish smile that gave him goosebumps and made his heart tremble with fear.With tears running down his cheeks, he balled his fists and spoke softly; “I promise, Raiden, from this very second, I belong to you. Every part of me is yours. My body, my mind, my soul, everything is yours. I will be your pet. I will do anything you ask of me. I will give you everything that I am. You own me, Raiden.”Watanabe Hiro used to be very rich. As the last child of the Watanabe family, he was pampered and spoilt by everyone but he was a good kid. He was obedient and friendly.
