Summary
Kagome has been living in the feudal era with Inuyasha for six months, and life has been peaceful. Inuyasha and Miroku are tracking a yōkai that was released from a seal by a landslide, and discover the yōkai was originally sealed away by Kikyō. The yōkai is called Ne no Kubi and is seeking the Shikon no Tama, not realizing it is already destroyed due to being sealed away for so long. Ne no Kubi attacks Kagome, mistaking her for Kikyō, but she wounds its head with a sacred arrow and Inuyasha kills it with the Kaze no Kizu.
