InuYasha Season 1 Episode 116

Sesshomaru battles with Jakotsu on Mount Hakurei while Suikotsu holds Rin captive. As Suikotsu is about to kill Rin, Kikyo fires an arrow at Suikotsu's neck making him change to his good alter ego. The counterpart wishes for Kikyo to remove the Shikon shard from his neck so he won't have to suffer the thought of killing anymore because of his evil alter ego. Jakotsu removes the Shikon shard and Suikotsu is reduced to a skeleton.
