Canine Warrior Chi is a japanese spitz entrusted with the Knowledge Orb and is one of five Canine Warriors who stayed in Kusa Village. Amaterasu is sent by Princess Fuse who had started to worry when none of the canines returned to her upon being summoned. Canine Warrior Chi explains that she knew Princess Fuse had summoned her but she was hungry and so decided to linger until he had eaten.
The Satomi Canine Warriors are eight dogs of various breeds who serve the Satomi House. Each possesses a different virtue in the form of a ‘Satomi Power Orb’ that grants them great power. Despite their duty to Kusa Village, Princess Fuse, and the Gale Shrine the Canine Warriors do not take their training seriously and will frequently disobey orders or ignore them completely due to having been spoiled by their previous master Yatsu. When the Gale Shrine fell to Crimson Helm and Kusa Village became ensnared in an evil essence Princess Fuse summoned the Satomi Canine Warriors. When they never came she sent Amaterasu to find them and upon their return started to train them seriously unlike Yatsu. An item called the ‘Canine Tracker’ is capable of locating the Canine Warriors when needed and will force them to return to Princess Fuse. But use of this item decrees that its user must prove their worth by beating the canines in battle, however only four of the eight Canine Warriors ever bother.
