Lolis, fan service, comedy. If these are the three most important factors for enjoying anime, then you'll love this series. This OVA series is shameless. It flings a few RotK generals at Japan from the sky in loli form without explanation where they proceed to go to school and mess around and show off their bodies and stuff. Plot points are picked up and dropped at random, things that seem like they're going somewhere trail off into gags, and if you think this series is a bunch of crap being thrown at a wall for fun just wait for the last episode where you'll be provenabsolutely correct. Ryofuko-chan is super cute, and her henshin sequence is one of my favorites, the nudity paired with the Chinese warlord theme is great. The ending is hilarious and proves how shameless this series really is.

As I said, you'll enjoy this a lot if you like parody and lolis and perhaps if you're into the Romance of the Three Kingdoms series or similar Chinese war general stuff as it exhibits quite a few characters from Chinese history in various forms(Lu Bu as a loli and Guan Yu as himself, for example). If lolis, parody, or Chinese history isn't within your interests, then I don't even know how you got to this page or why you would watch this.
