Hakurei, but is unable to pass, due to the mountain's sacred barrier; Rin notices Kohaku, and leaves Jaken behind to follow him through the barrier; Sesshoumaru later arrives, and when Rin returns, he realizes the "trick" to getting inside (i.e. Rin mentions youkai on the other side); elsewhere, Kanna shows Jakotsu and Bankotsu an image of Sesshoumaru and Rin through her mirror.

Hakurei and pursues Suikotsu; Sesshoumaru, though pained, enters the barrier, proceeding to attack Suikotsu and Jakotsu in unison; Kikyou—whom Sesshoumaru realizes is responsible for sealing Inuyasha for 50 years—makes the scene and uses her arrow to purify Suikotsu; Sesshoumaru and Rin witness Suikotsu's "death," and take leave of the mountain.
