Ep. 1: Towa Higurashi faces interrogation by a feudal lord who demands future artifacts like a Reiwa Era book and a bicycle seat.

Towa Higurashi refuses to reveal information from the future to a feudal lord, fearing it will alter the past. The narrative shifts to several years ago, where Kagome lives in the feudal era with Inuyasha and their friends. Inuyasha and Miroku encounter the Root Head, a demon sealed by Kikyō decades ago. The demon attacks Kagome, who is unknown to it, but Inuyasha destroys it, leaving a small fragment alive. Returning to the present, Towa is rescued by her twin sister Setsuna and first cousin Moroha. They identify the lord attendant as the ayakashi Yotsume in disguise and pursue it. Before leaving, Towa confiscates the book and the bicycle seat part.
