Yashahime: Princess Half-Demon Part 2

As the story of "Yashahime: Princess Half-Demon" goes, the twin sisters Towa and Setsuna are separated at a young age during a forest fire, with Towa ending up in the modern world while Setsuna remains in Feudal Japan. 10 years later, the two are finally reunited, but Setsuna curiously has no memories of her past, spending her days working as a demon-slayer. Bringing Moroha into the mix, she has a similar case of memory loss, and so "the three young women travel between the two eras on an adventure to regain their missing past," as described in the official synopsis of the series. 

Season 1 of "Yashahime: Princess Half-Demon" ends on a major cliffhanger, with Towa, Setsuna, and Moroha battling the Demon Beast King named Kirinmaru. The fighting is tough, and although Setsuna manages to land a blow on Kirinmaru, he then strikes her down, seemingly killing her. But is she really dead? Considering past anime, probably not, and the show hints at her possible return in Season 2. As for Towa and Moroha, the two develop better control over their abilities and engage in a serious battle, but in the end, they cannot defeat Kirinmaru. Meanwhile, Inuyashu, Kagome, and Rin are all still trapped, with Sesshomaru likely the reason behind it all.
