A tip for the translators: This story is full with sexual innuendos.
The Lesbian Knight's family name is not Lepman, but Rapeman, Zophie is Cyan Bitch (it comes back later with Bitch family and so on).
It has been quite some time since I read the novel, but I think even the countries were like that, with Pussy Empire and "Penni" Kingdom or something like that.
