I could tell it was a gag of some sort as soon as things got weird, but I wasn't sure if it was originally a satirical manga or if it was a comedic mistranslation. By the end, though, it's pretty obvious it's the translator having fun. For those in doubt, notice how "translation" is in scare quotes on the credits page. Now I'm curious if the real version will be posted, but it was pretty funny anyway.
