第 18 集: 殺生丸與麒麟丸對峙，東花與刹那則與控頓和透雪交戰
Towa and Setsuna confront Konton, who explains that the Rainbow Pearls spell disaster as they are fragments of an even greater power that must not exist, which was why they were scattered across the lands by none other than Zero. The Twins manage to destroy him, leaving Riku to reclaim the blue Rainbow Pearl from him. They rejoin Moroha and they overpower Toutetsu, who flees to Kirinmaru's ship for help. However, Kirinmaru drives Toutetsu off and Towa attempts to reason with him, asking for his cooperation to return Setsuna's dreams, but he refuses and fights the three half-demons. Sesshoumaru arrives and fights Kirinmaru to protect his daughters. Kirinmaru spares the Half-Demon Princesses, but reminds Sesshoumaru that he will do what Kirinmaru requires of him, and both leave. This leaves Towa, Setsuna and Moroha quite confused, as Towa wonders what her father's motives are. Moroha tries to get the essence of the Sacred Tree of Ages to emerge, but without success. Towa and Setsuna's ordinary mother, Rin, continues sleeping within the magical tree, as Setsuna plays a violin. (Source: Wikipedia)
