Sara

Sara was a cat yōkai who worked with Lord Gorai for building an enormous fortress at Mount Mansetsu.

History
Sara used the villagers from Yamasachi Village by using a mystical spell called Demon Blood Binding Spell to control them for building fortress. It was found by Inuyasha and the others at Sara's lair and Sara tried to defeat them, but it turned out oppositely and forced herself to leave her lair and lived at New Moon Cave.

At the later story, Sara kidnapped Miroku, Kagome, Sango and Shippō when Inuyasha and the other people entered the cave. At the exact moment Sesshōmaru and his followers met Sara, who tried to used Sea God's Kamuitama by using Demon Blood Binding Spell again. Sara intended to defeat Sesshōmaru and Janis, unfortunately she was killed during the battle.
