This OVA is a 3 part OVA one about the present and 2 are flash backs. The first one is about Asuha and Lotte doing a homework and Asuha chooses about pants and Lotte chooses about a dragon egg. The second one is about how Zelda(the head security) became Lotte's guard and about Zelda's master. The most important one is the last one where The Queen meets Naoya. If u like the original series, watch this or if u are just looking for echi stuff this has some...There are not a lot of new characters would change the story a lot...they are minor characters...

Still has some humor and the echi.
