Ukiyo-e artist Shunsai, who lives in a nagaya in downtown Edo, is secretly asked by Kansuke Edoya, a kimono shop owner, to draw an ukiyo-e shunga on a pillow folding screen. Therefore, Shunsai drew a shunga modeled on the love affair between Nikichi and Otoyo, a couple who ran away next door, and named the man and woman in the picture 'Harunobu' and 'Otama'. Then, Harunobu and Tama are lured by the gasping voices of Nikichi and Otoyo and escape from the screen, killing Nikichi and Otoyo. Upon hearing this news, Genjutsu-user female doshin, Genoryu, embarks on a case.—Leo Nishimura
