This film appealed to me because of the music, singing and dancing, never mind if there were soft-porn sex scenes during its entirety. The melody reminds me a bit of nursery songs, but the lyrics seem to have double meanings. The electro pop fusion music is pleasant to the ears and the dance numbers in the fish factory and that with the kappa elders were my top favorites, in fact, I was impressed with the song arrangement on the sing and dance number with the kappa elders, with chirping and meowing sounds incorporated quite harmoniously to the melody.  And the dance steps, my, how they remind me of zumba steps and dance steps of mascots!  This is one film that is  peculiar, unique yet also heartwarming. Imaoka is really a master of porn infused with the wholesome musical style!
