Ninja 53: Female Ninja Agent Binin-Maiha

忍者 くノ一捜査官 美忍舞刃

Also known as TNI-53

The Jaen Clan sends in the Evil Priests, masters of secret pressure points, to defeat Minobu Maiha and obtain the secret of his power. During the battle, Maiha is unknowingly struck in a secret pressure point, gradually causing pain, and eventually is rendered agonizing by a secret technique that causes intense pain all over his body just by trying to move. Maiba still goes to fight, but is taken prisoner by the Evil Priests, who pierce his entire body with needles, increasing his body’s sensitivity, and toying with him.
