Episode 181

In Pursuit of Naraku is the 14th episode of InuYasha: The Final Act.

Plot
Sesshomaru visits Totosai, who confirms that his father gave him Tenseiga so Sesshomaru could perfect the Meido Zangetsuha. Meanwhile, Naraku begins pursuing Kohaku to retrieve his jewel shard, however Kohaku's shard is still being protected by Kikyo's powers and remains too pure for Naraku to easily get. Inuyasha's group arrives, and Naraku taunts Sango by saying Kohaku runs from her to forget his past. She states that she already knew that, but will still fight for him when he needs her. She attacks with Hiraikotsu and to her surprise, it now has its own demonic energy and it is able to injure Naraku. Inuyasha follows up with an Adamant Barrage attack, Kagome fires one of her arrows, and Miroku attempts to use his wind tunnel, but the injured Naraku manages to flee. Afterwards, Kohaku tells them that because his shard is still protected by Kikyo, it may be useable in the battle with Naraku. Kagome realizes that the image of purity within the Shikon jewel's core that Kanna showed her before her death is actually Kikyo's light.
