In a distant universe resembling our own, a highly advanced civilization thrived under the creation of a mysterious young man named Leo. Despite the prosperity, malevolent forces led by a group of evildoers plunged the land into chaos and hardship, sparking a devastating war. Leo, the architect of this advanced society, found himself betrayed by his once-trusted friend, Peter, who stabbed him in the back.
However, in a mysterious turn of events, a system manifested in Leo's eye, signaling the beginning of a new adventure. Leo, realizing he was no ordinary human, recounts his origins. Born in Japan in the late winter of 2025 and abandoned as a baby, Leo met his fate during a high school incident where he sacrificed himself to save a girl from a raging truck. Death, though, was not the end for him, as he found himself reincarnated in a world known as Genesis.
In this new realm, Leo became the seventh son of the Duke of Lavintan and adopted the name Leo James Lavintan. His childhood was marked by rigorous training in piloting the Guardian Knight, a type of advanced mecha with various forms and powers. Leo's father, the most skilled Guardian Knight Rider in the Kingdom of Havintel, played a pivotal role in shaping Leo's destiny.
Now, Leo embarks on a full-fledged adventure, armed with his unique abilities and the determination to overcome the chaos that plagues the universe. The stage is set for Leo to unravel the mysteries surrounding his rebirth, confront the betrayal of his former friend, and emerge as a beacon of hope in the face of impending war.
