The series is focused on Yatora Yaguchi, a fairly popular student who excels in school, who became fascinated by a painting so deeply that it inspired him to try his hand at painting.
She prefers to wear a ribbed, short-sleeved turtleneck sweater and overalls tied around her waist when making art.
Her introductory painting is one of two angels, her second one is a drawing of the Greek goddess Nike, and later she is shown to have expanded her repertory by making a painting of multiple hands in Buddhist prayers.
