In the first episode of Hataraku Maou-sama, what is the "Underworld" language based on?


In the first half of the first episode of Hataraku Maou-sama, we can hear
conversation between Satan and Alsiel in "Underworld" language. Is the
"Underworld" language based on a real language, or is it just plain gibberish?




According to [this article](http://purisoku.com/archives/6496740.html) (which
cites from a 2ch thread), the language is is pretty simple:

> The Entean language is basically letter substituted English, with vowel
> keeping their original position, while the consonants are reversed, so B=Z,
> C=Y, D=X, ... and vice versa.
[code]

>        ABCDEFGHIJKLMNOPQRSTUVWXYZ
>     -> AZYXEWVTISRLPNOMQKJHUGFDCB
>  
[/code]

>
> For example:
>
>   * 人間 human → tupan
>   * 世界 world → foklx
>   * 魔王（芦屋による呼称） majesty → pasejhc
>

They say it with such enthusiasm, too:
