Okugata

Lady Okugata is the head of the castle who became the Infant's victim of manipulation and capture innocent people until Kagome Higurashi was found.

In the Story
Lady Okugata was the first to fall victim to the Infant's power of manipulation (it is unknown what darkness the Infant found in her heart), and was used to capture any travelers that were coming from the direction of Mount Hakurei. Presumably, she is also how the Infant got his outfit. Once Kagome had been captured, Lady Okugata was released by the Infant and died.
