Mai, a practitioner of the Hotaka-style ninjutsu, enters the "Crown of Goliath" martial arts tournament to retrieve a secret scroll stolen from her village. She is struck in her pressure points by a wicked wrestler, leaving her body stiff and battered. Despite this, she manages a come-from-behind victory using her secret techniques. Her next opponent is a ninja who can create clones; though there is only one real body, she is overwhelmed by the attacks of three, falling into confusion. Furthermore, she must defeat powerful enemies, including a robot equipped with weapons that attacks with brute force, to reclaim the scroll. However, once the organizer Wolgen discovers her true identity, Mai is captured and tortured by Wolgen to force her to reveal her purpose. With the pride of the Hotaka clan in her heart, Mai burns with fighting spirit against her nemesis, but... In the end, the kunoichi's fate is to lose control of her bladder, grovel in dogeza, and beg for her life. [BAD END]
