A handsome, effeminate ukiyo-e artist who charms young, attractive women into letting him draw ukiyo-e portraits of them, and then allowing his yakuza employers to kidnap the girls and sell them as European sex slaves, using the ukiyo-e painting as the advertisement. He does the same to Fuu; however, as she actually had appreciated his art, he feels guilty and failingly tries to free her. Moronobu also seems to be the object of unrequited attraction by the yakuza leader's wife, which aids his survival when the yakuza discover what he did. He later tells Mugen everything, who proceeds, along with Detective Manzou, to successfully rescue her and expose the slave trade. In the end he tries to stowaway for Europe with a nude painting of Fuu with sunflowers, inspired by his number one fan, (on account of how she spared the time needed to glance at his work), Fuu. Although she never finds out if he makes it to Europe, Manzou informs us that Moronobu was captured shortly after and returned to Japan but his painting made its way to Holland, where it would inspire Vincent Van Gogh centuries later. Hishikawa Moronobu is based on an actual historical figure.
