Alliance

It all began when Kagura and Kanna were summoned to get Kaguya out of the Mirror of Life. To release Kaguya from the mirror they used five sacred objects. Those objects are: the Cloth of the Fire Rat, Crystal from the Dragon's Neck, the Stone Bowl of Buddha, Crowey's Shell, and a certain herb (don't know what it's called.) Each time they found those five sacred objects, Kanna or Kaguya say a spell and drop those objects in the water near Mt. Hakurei. Kagura found the Cloth of the Fire Rat by battling Inuyasha and slashing off part of his robe. Crystal from the Dragon's Neck was found by Kanna. The Crowey's Shell was in Kohaku's protection while the Stone Bowl of Buddha was in Kikyo's hands. Kagura and Kanna wanted to help Kaguya out of the mirror, because once they got Kaguya out of the mirror, Kaguya promised Kagura everlasting freedom. Little did Kaguya know that Kagura's and Kanna's intention all along was to get Kaguya out so Naraku would absorb her powers. Kaguya thought Naraku was dead from the beginning but he faked his death. So in the end, Kaguya didn't have any allies, mostly everyone was her enemy.
