Episode 159

 is the one hundred fifty-ninth episode of InuYasha.

Summary
Kohaku closes the shrine and grabs it and runs from Sango's attack. Miroku turns to fight the rat demons, but they are so focused on their destination they ignore him.

InuYasha and Kagome are looking at the tree when Hakudoshi arrives. He attaches some slug demons to the tree, and they begin to dissolve the tree. InuYasha races to attack Hakudoshi while Kagome shoots the slugs with her arrows. InuYasha hits Hakudoshi with his Wind Scar, but the pieces flee leaving a warning behind: so long as Kikyo keeps running, Naraku will continue to attack. The tree's spell is weakening, so InuYasha and Kagome hurry to slay the rest of the slugs.

Sango confronts Kohaku, while Miroku and Kirara try to deal with the rat demons. InuYasha and Kagome slay the rest of the slugs, but the tree is no longer attracting the rat demons. They decide their only option is to destroy the shrine, and head for Sango and Miroku.

Kohaku struggles with Sango, and flees, but is attacked by rat demons. Sango saves Kohaku, but cannot break through the barrier around the shrine. She grabs Kohaku as they are both buried by rat demons. Kirara tries to pull them all free, but is overcome. InuYasha arrives as a sacred arrow breaks the barrier surrounding the shrine. InuYasha destroys the shrine, and the rat demons are destroyed.

Kikyo is standing nearby, looking down, then leaves. Sango and Kohaku awake, injured but ok. With the saimyosho looking down, Kohaku runs away and is taken by Hakudoshi. Hakudoshi asks Kohaku who Sango is and why she protected him, but - still pretending to have no memory - Kohaku claims not to know his sister.

Sango is recovering from her wounds; as she thinks about her brother's actions she cannot forgive him the evils he has committed, but is conflicted by her love for him.

Kikyo gives her helpers a piece of her hair and sends them off. She commits herself to finding Naraku.
