Episode 176

Without his jewel shards, Koga takes his companions and retires from the fight with Naraku, leaving desire for revenge to Inuyasha and his group. Meanwhile, Sesshomaru visits his mother to ask how he can make his Meido Zangetsuha stronger. She summons a HellHound for him to battle, which takes Rin and Kohaku into the void of the netherworld. He follows and defeats the beast and rescues them. Though Kohaku is able to move within the void, Rin is not. The darkness of the Abyssal Void envelopes her and Sesshomaru confronts a guardian of the dead. Rin is dead, and Sesshomaru is disturbed to realize he is not sure Tensaiga can revive her again.
