It's a Steel Jeeg reference. Probably because of the similarity between the katakana for "Jeeg" and "Shinku" in the title.

Thanks! I figured it was some kind of parody but I was lost.

How did I miss something so awesome?! It's translated now.

BTW, I just realized Rozen Maiden has resumed serialization. Maybe there will be a third season after all? :D

I didn't know that, I still haven't finished season 2...
