Acting under Naraku's request, Kikyo traps the Inuyasha gang with an illusory mist, causing them to have nightmarish visions.

Inuyasha and the others are introduced to Totosai, the swordsmith who forged Inuyasha's Tetsusaiga and Sesshomaru's healing sword, Tenseiga.

Inuyasha and Sesshomaru continue fighting for the Tetsusaiga. After the fight, while Sesshomaru is recovering, a little orphan girl, Rin, tries to bring him food. When her village is attacked by wolf demons, Sesshomaru returns the favor and helps Rin. Meanwhile, Kagome senses a jewel shard. Inuyasha and gang follow her lead to the massacred village, where they are quickly surrounded by wolves and Koga.

When Koga, a wolf demon, kidnaps Kagome and Shippo, Inuyasha, Miroku and Sango go on a rescue mission. But there's another foe they must defeat first, before they can reach their kidnapped companions.
