Yumigami (God of the Bow) is the Celestial Brush God of the night and the Celestial Brush Technique Crescent (Gekkō, Moonlight) which grants the ability to change day to night. She takes the form of a rabbit with a mochi-pounding mallet making rice paste and had hid among the constellations to escape the evil of the world below but was devoured by a fish and revealed by its capture. She is one of many of the original brush gods from Ōkami to not return in Ōkamiden.
The thirteen Celestial Brush Techniques are each a different brush stroke, mark, or symbol capable of controlling the time, elements, environment, ect as "good brush work has its own soul" and have taken on the form of one of the Chinese zodiac animals. They are born of and wielded by the sun goddess Amaterasu for whom they hold great respect as their ‘mother’. 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. A Celestial Brush Technique can be canceled out by drawing the same symbol over it.
