The "office lady is an otaku" genre has more works than you'd imagine. In a sense this is probably the best mixture of the otaku topic and the actual plot. At first characters look and behave similar to their 0079 counterparts, but as the plot progresses it becomes an office satire about Gundam.

The chapter by chapter comedy is solid, the gundam is in no way subtle but the jokes go beyond references and in general it would be good even without the Gundam angle.

Sadly the final chapter is a huge insult that has to take away points from this. Not only that but it got cut right when Zeta's AEUG was forming and we had so many characters to develop. There wasn't even time for a Hitler comparison!

I completely recommend this manga but be prepared for the worst final chapter you could ever get, way worse than anything you could imagine.
