Ōkami Amaterasu is the Shinto sun goddess in the form of a white wolf with orange-red markings. She wields one of three divine instruments: the Reflector, Beads, and Glaive but the most iconic is the Reflector which appears as a spinning green Chinese mirror surrounded by flames. It was a gift from Sakuya and is a weaker version of the Solar Flare. Additionally Amaterasu can temporarily stop time to draw things into existence with the Celestial Brush. With the brush she can direct water, fire, wind, bloom flowers, bring out the sun and moon, cut enemies and obstacles alike as well as many other feats. The thirteen Celestial Brush Techniques are each a different brush stroke, mark, or symbol that "has its own soul" and take the form of a Chinese zodiac animal. Anyone can use the Celestial Brush Techniques but years of practice are needed to master them unlike Amaterasu who is the only one known to have and been able to possess all thirteen techniques. The gods of the brush all hold Amaterasu in high regard as their mother.
Ōkami Amaterasu was once known as Ōkami Shiranui and was the guardian deity of the Celestial plain. When Orochi attacked she defended her home and the two fell to the earth locked in combat. On earth Orochi started a right of sacrifice, demanding a maiden every year while Shiranui awaited the birth of Nagi the ‘chosen one’ but her mysterious presence caused the locals to mistake her for a familiar of Orochi. When Nagi faced Orochi, Shiranui arrived to fight at his side. The two sealed Orochi away but Shiranui took a fatal blow to save Nagi and perished. A shrine in her honor was erected below the sacred tree Konohana but after a 100 years had passed Orochi’s seal was broken and a cursed spread across the land. Sakuya awakened Ōkami Shiranui from her slumber to restore the land and face Orochi once more. Now known as Ōkami Amaterasu she destroyed Orochi, reclaimed the thirteen brush techniques she lost, fought Yami, and returned to the Celestial Plain.
Along her journey Amaterasu was accompanied by her pint-sized companion and guide Issun who affectionately called her Ammy. She became so close to Issun that she almost refused to return to the Celestial Plain when he was unwilling and unable to accompany her there. Issun later became her Celestial Envoy and restored peoples faith her during her most desperate time of need. In Ōkamiden she has a son named Chibiterasu.
