And now, Renkotsu has discovered Kagome's ability to see Shikon Jewel shards. Can the Wind Scar defeat Bankotsu and his Banryu?

Inuyasha battles with Bankotsu on the island of Hijiri without being able to use the Wind Scar. Miroku learns that Naraku is using the great priest's power to create a barrier around the island of Hijiri weakening Kirara and Shippo, and making Inuyasha unable to use the Wind Scar.

Hakurei also, but then, Inuyasha suddenly smells the blood and scent of the wolves and rushes over.

Jakotsu attacks Sesshomaru while Suikotsu kidnaps Rin. However, Suikotsu's good alter ego takes over temporarily as he takes Rin to the village where he tended to children.

Meanwhile, Kikyo and Sesshomaru head off to go after the three despite the barrier on the town.
