The fifth DVD of loli of the three kingdoms anime Koihime Musou includes some of the most (formerly) steamy episodes to date; naturally, oppai are visible in abundance, unprecedented abundance in fact.

This looks to be an outstanding success in DVD marketing. Giving a reason to watch the formerly neglected SD characters is also a nice touch.
