Yatsu is a member of the Satomi House, husband to Princess Fuse, former master of the Canine Warriors, and priest of the Gale Shrine in Kusa Village. The Canine Warriors disobedience is credited to Yatsu for spoiling them and going easy on their training. He was killed by Crimson Helms minions while he was weakened by sickness leaving Princess Fuse to assume his duties. Yatsu’s lingering fears about Kusa Village and Princess Fuse kept him earthbound in the Gale Shrine.
Having eventually gone blind his inner eye could judge a person’s true form which allowed him to perceive Amaterasu as a "maiden most fair" and Issun as a "little booger". When Susano came to meditate at the shrine and was plagued by nightmares Yatsu attempted to offer what aid he could but was barred entry by Orochi. After the defeat of Crimson Helm Yatsu’s worries were put to rest and he ascended to the heavens.
