Yashahime: Princess Half-Demon

Towa Higurashi learns about an incident that took place decades ago involving a half demon named Inuyasha and a priestess named Kagome.

Half-demon twins Towa and Setsuna are separated from each other when a mysterious tunnel sends Towa into the future, where she is found and raised by Kagome Higurashi’s brother Sota.

In the present day, a demon emerges through the Sacred Tree at Higurashi Shrine with Setsuna, Towa’s twin, and the bounty hunter Moroha in tow. Towa, Setsuna, and Moroha struggle to battle the demon, whose powers have been strengthened with two Rainbow Pearls, but seeing Setsuna in trouble awakens Towa’s latent demon powers.

Towa decides to return to the feudal era to help Setsuna regain her memories. The trio enter the corridor leading to the feudal era, but within it awaits the spirit of a certain priestess.

Safely back in the feudal era, Moroha heads to the corpse dealer to claim her bounty. Meanwhile, Towa and Setsuna take on a request to slay Jakotsumaru, a boy who has been extracting bones from humans and beasts in order to revive his father, the demon beast Tokotsu.

Travelers are going missing one after another. Towa, Setsuna, and Moroha head to the northern mountains to crack the case, but instead they find a village completely overrun by ghost cats!
