B'T-X

This is a story about a boy and his companions growing together, pursuing their dreams bound by friendship and belief. Established by the Mechanical Emperor, the Mechanical Empire harbored ambitions to conquer the world. They created mechanical lifeforms with independent thought, combining Brain, Blood, Beauty, and Bravery—known as Battler Total (B'T). These beings possess incredible combat power but run on human blood, swearing absolute loyalty to the first person who offers them their blood. In the early 21st century, countless warriors of the Empire piloted B'Ts, launching wars across national borders. Cities and villages lay in ruins under bombardment, homes turned to scorched earth in an instant, and people were displaced, wandering in the depths of sorrow and despair... However, even more terrifying was the secret cultivation within the main tower of the Imperial base of a monstrous creature capable of devouring the entire Earth and all living things—the ultimate B'T, Lafal... Five years prior, Karen, one of the Four Holy Generals of the Mechanical Empire, was the first to discover the Mechanical Emperor's ambition. She fought desperately to escape the Empire. The only hope to defeat Lafal was light. While searching for a powerful source of light, she encountered a young man radiating brilliant brilliance—Tetsuro Koumiya. Five years later, to sustain Lafal's growth, the Mechanical Empire kidnapped Tetsuro's older brother, Kotaro Koumiya, a genius scientist in the field of mechanics. To rescue his brother, Tetsuro headed alone to the Empire, where he met Karen's B'T—the legendary B'T X. Thus began a fierce battle against the Mechanical Empire...
