Episode 76

Miroku and Sango get captured and are emprisonned with Kagome and villagers, to be sacrificed in order for the demon-panther to resurrect their leader. InuYasha gets from Myoga, then Jaken, the story of how his father and his allies battled and defeated the panthers eons ago, then how Sesshomaru did the same fifty years ago (though at a huge cost of lives), while InuYasha was under the spell of Kikyo. Thus explaining the hatred of the panthers for his blood, and part of Sesshomaru's despise for his brother, who fails to come to his aid the one time he needed it. Koga gets told the same story from the forest demon, and joins the two brothers as each attacks one gate of the panthers' fortress.
