The Japanese government initiated a military initiative that involved modifying schoolgirls to become Tekki - individuals with steel-reinforced bones and artificial muscles for enhanced strength. These Tekki possess exceptional skills in wielding the katana and engage in street battles to determine the best of the best. To maintain and upgrade their abilities, Toui - medical experts - are responsible for repairing the Tekki. Sakuradamon Academy is designed to cultivate girls such as Honoka Asami - a formidable and enigmatic Tekki - and Nagamitsu Yomogi - a gifted Toui. As they navigate the perils of campus life, Asami and Yomogi must unite their skills to survive.
