The demon Shishinki approaches Sesshomaru for a fight, having been defeated by Sesshomaru's father long ago.

Sesshomaru attacks with his Meido, but Shishinki's absorbs it.

Kohaku remains unconscious after being stared down by Magatsuhi, the evil will. Kagome is worried, but she has to buckle down and study for her entrance exams, so she decides to return home.

Sesshomaru chases after the evil will, Magatsuhi. But it's only part of a trap set up by Byakuya of the Dreams. Magatsuhi finds Kohaku lying unconscious, and he tries to deliver his Shikon shard to Naraku.

Kohaku successfully drives Magatsuhi out of his body just as Sesshomaru arrives, who manages to cut Magatsuhi in half, destroying part of him. Naraku then tries to take Kohaku's shard himself, but Sesshomaru attacks with his Bakusaiga, which causes Naraku's body to explode.

Naraku heads for the Bone Eater's Well and vanishes! Before disappearing, Naraku makes his last wish for Kagome, injured at the hands of Byakuya, to be swallowed into Meido, the Path to the Underworld.
