Mina Tepes is the ruler of all vampires who has just moved to Japan. After the Tokyo government granted her an offshore island known as the "Bund" for paying off the entirety of the country’s debt, Mina has decided to set up a special vampire district in the middle of the city’s harbour, a choice that’s far from popular. With many people after her life, she is in need of a full-time servant and bodyguard and her choice is Akira Kaburagi, a member of the respected Earth Clan. Now Akira must work to keep Mina safe and attend to her every whim as the young princess attends school. But what exactly are Mina’s motives for setting up the vampire district in the first place, and just who is behind all the attempts upon her life?
Both of those manga feature a badass teenager and his loli mistress as the main characters (read it as you see fit ;) ). Dance in the Vampire Bund has more romance going on while Kurenai has a harem in place of romance. Anyway, those series do resemble each other, so if you liked one of them you might want to give the other one a try.
