InuYasha: The Final Act

Kanna's Gravestone (1x11)

:

InuYasha's party hides in a cave with a barrier, but the mirror demon finds them and breaks through it. As InuYasha fights it, his body goes into demon form but InuYasha somehow maintains control of his senses. As he wounds the demon, they are transferred to Kanna, who is controlling it. Watching from a safe place, Naraku orders her to keep the demon going until it kills them, or until their party kills her by killing the mirror demon. InuYasha switches his target to the replica Tessaiga and successfully breaks it, which restores the power to his own sword and his body to his normal half-demon state. Kanna gets closer to the group, but InuYasha refuses to kill her. Naraku makes Kanna and the mirror explode in a shower of glass shards in an attempt to wound the party. One shard of glass enters Kagome's eye. Through it, the dead Kanna gives her a clue as to how they can kill Naraku.
