Ganno

Ganno is described as being in his mid-sixties, with crimson hair and thin, sunburnt arms. The red paint that adorns his fingernails makes him easily identifiable to others, even from a distance. In the manga and anime, Ganno has white long hair and fair skin.

Like his father before him, Ganno was a painter active in Redaku's capital city. Painting became an obsession for him over the years, to the point that he was never without a paintbrush and took little interest in activities outside of painting. Despite these eccentricities, Ganno was evidently quite popular, as he was often hired to paint portraits of nobles living in the capital. But when it was discovered that he was using these portraits to pit rival nobles against each other, he was arrested, convicted of state treason, and sentenced to seventeen years in prison. Despite his imprisonment at the Astronomy Research Institute, Ganno did not give up his love for painting: a month prior to the events of Sasuke Retsuden, Ganno was able to collect a number of reddish-brown stones from the quarry that he and the other prisoners were excavating. He spent the next several nights carefully crushing the stones into a fine powder, which he then boiled along with skin peeled from his own foot. The resulting concoction was a red paint. Using pine needles as brushes, he carefully applied this paint to his fingernails. Because of the nature of his "canvas" and the fact that his tools would inevitably be confiscated by the prison's guards, Ganno's paintings were inherently temporary. Nevertheless, he remained committed to his craft, completing an average of one art project per week.
