He is a legendary figure in the pleasure district, serving as "Ryuki Tayu" at the Shirasagi-ya house. He is in a class of his own in terms of appearance, performing arts, education, and bedroom technique. The prime of a male courtesan is usually between fifteen and twenty; older men typically move to the background or retire. However, Ryuki's popularity is so great that he cannot retire, and his ransom is so high that freedom remains out of reach. He personally wants to retire and prefers teaching etiquette, dance, and instruments to the younger generation. He secretly shares gifts of sweets from customers with his juniors and the young servants.
