Hanyou no Yashahime: Sengoku Otogizoushi

Synopsis

Riku pays a visit to Jyuubei, who gives him a large sum of gold for his services and reveals that he intends to use Towa, Setsuna and Moroha in his plan to defeat the remaining three Perils so that he can obtain all seven Rainbow Pearls and gain untold demonic power. Meanwhile, the three girls follow Yotsume to Kyuuki's hideout. Kyuuki uses the Purple Rainbow Pearl to empower Yotsume, who uses his power to put Towa, Moroha and Takechiyo to sleep. In their dreams, it is revealed that Moroha was given away at Kagome's urgent request as a baby and entrusted to Hachiemon, when Inuyasha and Kagome prepared to confront Kirinmaru and Sesshoumaru, Takechiyo was entrusted as a baby to Jyuubei by Miroku for unknown reasons, and that the Dream Butterfly had carried Setsuna's memories to the Sacred Tree of Ages, where the adult Rin is imprisoned. Setsuna, being incapable of sleep, resists Yotsume's powers and destroys him. Kyuuki reclaims the Pearl and confronts the three girls, stealing Towa and Moroha's energy due to them still being under influence of Yotsume's spell. As Setsuna fights Kyuuki alone, Moroha reminds Towa about her natural ability to steal demonic energy and Towa uses it to fight and defeat Kyuuki with the Souryuuha attack she inherited from her dog-demon father. After the battle, Riku arrives to obtain the purple Rainbow Pearl, and Jyuubei later introduces him to the girls as his and Takechiyo's employer, rewarding them for Kyuuki's defeat with part of the gold he received from Riku.
