My presence has marked your eventual demise.
Yissss and with our eventual attempt at smartening us up we can be the new Lelouuuuch and we can fuck up the Nazi's and then become the Holy German Reich Emperor!!!11111!!!!112We need to go around Japan and dig out occult items.

Yes. Mechs + Magical Powers + Japan.
Code Geass Nazi Spinoff, anyone?
