A dire threat exists to awaken an ancient vengeful spirit—one that will unleash destruction in 1908 Tokyo.

Kato uses magic to impregnate Yukari, in order to conceive a child with stronger powers. It’s now 1923 where Yukari's daughter is a young girl.

The plot shifts to 1927 Tokyo and its plans to build a subway system.

Keiko receives spiritual aid from Kuroda and Masakado's spirit and sets off to stop Kato once and for all.
