Investigation of Mount Hakurei
Inuyasha's group investigates Mount Hakurei, despite its purifying barrier affecting demons and half-demons. They discover Naraku's hideout inside the mountain. Meanwhile, the Band of Seven, led by Bankotsu, attacks a castle to retrieve Bankotsu's halberd, Banryu.
Conflicts and Alliances
The Band of Seven's internal conflicts intensify as Renkotsu targets Kagome to prevent Bankotsu from discovering his theft of jewel shards. Kohaku saves Rin from Naraku's demons, and Naraku orders the Band of Seven to retreat. Inuyasha's group, obstructed by a demon puppet, continues their pursuit.
Battle at Hijiri Island
Inuyasha's group locates a place with the same scent as the strange demon puppet, leading them to Hijiri Island. They confront Bankotsu at Saint Hakushin's tomb-shrine. Despite the saint's purifying aura, Miroku neutralizes it, enabling Inuyasha to attack. However, Bankotsu escapes, and Inuyasha's group deduces the saint's allegiance to Naraku, returning to the mountain for a final confrontation.
