Naraku's Porcupine-Demon Attack
Naraku's Kongosouha spears control the corpses of poisonous porcupine-demons. Miroku, resting under Sango's care, is unable to fight, but the rest of the group returns to defeat the porcupines.
Naraku's Trap
Naraku traps Kikyo, Inuyasha, and Kagome with spiderwebs in the sky, which worsens the miasma in Kikyo's body. Kagome is unable to purify the miasma because the webs have touched the malice. Inuyasha and Kikyo stay behind while the others search for a bow that can heal the miasma.
Kagome's Test on Mount Azusa
Sesshomaru prevents Byakuya from catching Kohaku. Kagome and the others arrive at Mount Azusa, where the spirit of the mountain tests Kagome, breaks her malice, and gives her the bow needed to save Kikyo.
