Amaterasu is the Celestial Brush goddess of the Sun and represents the dog in the twelve East Asia zodiacs. She is a white wolf with ruby-red markings throughout her body and a tail shaped like a calligraphy brush. Floating right above her is her Divine Instrument, the fiery Reflector, which she uses as a weapon to fend of evil. Née the revered Shiranui, master of all Celestial Brush techniques, she reincarnates a century later as the weakened Amaterasu after being defeated by the looming threat of Nippon, Orochi. She starts off with her original brush technique, Sunrise, which allows her to turn night into day and disperse any darkness foreboding.

Accompanying Amaterasu in her journeys is Issun, a vein and flirty Poncle from the village of Ponc’tan. Similar to what his grandfather, Ishaku, did for Shiranui, the traveling artist guides and aids Amaterasu all throughout her pursuit. Together, they overcome challenges to try and regain the Celestial goddess’s former powers to once again attempt to subdue the very foe that once bested her one hundred years back.
