and social order, whereas Gennai believes that it embodies wisdom and creativity. The two agree that a fart is nothing more than a useless discharge, and that it cannot compare to the officially sanctioned work traditionally labeled as 'productive', such as the mental work that comes with running Tokugawa society; however, they disagree on the meaning and implications of this discharge. Kinkichirō argues that it goes against everything that the "true sages" taught society about human decency and etiquette, but Gennai sees the fart-ist's creativity and wisdom in being able to make such useless excess into music. By presenting it this way Gennai exposes a problem with the categorization of material and media as either high or low.
Throughout the story, Gennai continues to critique both the concept of high culture and the attitude of its custodians.

''. The ''kappa'' plans to seduce the actor and then drown him, in order to bring him back to hell. However, the ''kappa'' falls in love with the young actor. Not wanting to subject his lover to eternal suffering in hell, the ''kappa'' brings back a less attractive ''onnagata'' in an unsuccessful attempt to appease Enma. Enma then ventures out into the mortal realm to find Kinkunojō himself, but he is defeated in battle by the great hero actor
Ichikawa Raizō I. It is then revealed that the whole story has actually been Raizō's dream, foretelling his imminent death.
''A Lousy Journey of Love''
Continuing the theme of satirical publications, Gennai's piece "A Lousy Journey of Love" is part of ''Blown Blossom and Fallen Leaves'', an anthology of his work compiled and published posthumously by his friend and trainee,
