Summary
Shippo awakens in a pile of hay and with a large bump on his head. He is disoriented and confused at first. Kohaku and Kaede are in the wooden building with him when he suddenly recalls what happened:

Shippo yells about having to stay behind. Inuyasha, Kagome, Sango, and Miroku all tell him its too dangerous for him to tag along. Inuyasha adds that he'll already have his hands full with looking out for Kagome since she had lost her spiritual powers. Sango turns to Kohaku and tells him that he also must stay behind. She doesn't want him to waste the life that Kikyo gave him. Shippo grows teary-eyed, and Inuyasha informs him that he must stay behind in case they don't come back. When Shippo started to argue again, Inuyasha knocked him out by hitting him.

Shippo runs towards the door of the building to go after them, but stops once he gets outside. The sky has turned darker than before as the evil aura of Naraku and the tainted jewel.

Inuyasha and the others are talking as they grow closer to Naraku. Miroku makes a comment about how Inuyasha had been unlike himself when he told Shippo they may not come back, but Inuyasha defends himself by saying it was the only way to get Shippo to stop complaining. The mood of the conversation grows more serious as they all recognize the grave danger of what they are getting into.

Sesshomaru appears in front of Naraku, who has become a gigantic spider. Sesshomaru uses his Bakusaiga when a wave of demons rush at him, and they all die instantly. Byakuya appears and is impressed with the power of Sesshomaru's sword. He affirms that the girl Rin is inside Naraku. Naraku suddenly shoots out a web towards Sesshomaru, but he skillfully dodges the attack. Inuyasha and the others appear. The demon Kagome and Inuyasha were riding on is destroyed when it runs into the poisonous spider webs that Naraku shot out. Inuyasha jumps off the demon with Kagome in his arms. Suddenly, Naraku opens.
