Sango fights Inuyasha, believing him to be her enemy. Naraku's plan is to have her fight to the death using the power of the Shikon Jewel shard. But Sango listens to Kagome and is no longer suspicious of Inuyasha.

Sango reveals the secret story of the Shikon Jewel's birth. Midoriko, a priestess with powerful spiritual powers, fused with many demons after a battle to the death. She absorbed the souls of the demons into her own, punched out her soul, and died. Her soul is the Shikon Jewel.

Inuyasha and the gang meet Taromaru, the son of a village leader. They go to the Temple of the Water God, where children are being sacrificed. The Water God has a sacred treasure and toys around with the group.

After Miroku sucks a mantis demon into his Wind Tunnel, the demon manages to rip the tunnel. Panicked, Miroku returns to the home of his mentor, Mushin, to repair it. Haunted with memories of his father's death, Miroku must come to terms with his Wind Tunnel as demons attack Mushin's temple.
