Seira, the Kougaiger, fights against the Ayakashi demons. However, a clan of shinobi known as the Musasabi-shu appears, and the massive Eihachi attacks Seira! Cornered by his overwhelming power, Seira manages to escape using a blinding technique, but she is spotted by the lower-ranking shinobi of the Musasabi-shu, leading to another battle. Despite being low-ranking, they have incorporated Eihachi's blood, allowing them to withstand Seira's attacks and assault her! Even their leader, Danshichi, joins in, lewdly tormenting Seira's body. But Eihachi, wanting to use Seira as a womb for his own offspring, cuts down Danshichi and closes in on her with his massive frame... Battered and broken, Seira is violently defiled by Eihachi, reduced to a state unbecoming of a shinobi, begging for mercy... [BAD END]
