Ai Tennouji

Ai Tennouji is the ninja princess of Shimoga Village and the twin elder sister of Tennouji Mei. Having once suffered a grave injury that left her physically frail, and carrying a sense of inferiority regarding her own abilities, she is largely unfamiliar with the outside world. Nevertheless, armed with the blade known as 'Shinken Muku,' she set out alone to Tokyo, driven by an unyielding resolve to reclaim her younger sister, who had defected to the enemy. In the 'Tokyo Recapture Arc,' her strong-willed presence becomes a vital force supporting the protagonist and propelling the story forward.
