From Seven Seas:

After millennia in hiding, Mina ?epe?, the princess of the ancient covenant and ruler of all vampires, wants change. Using the vast wealth of the ?epe? line, she has paid off the entire gross national debt of Japan and in so doing, gained the authority to create a "special district" off the coast of Japan that is to become the future haven to vampires the world over!

Now, on the eve of the landmark press conference announcing the existence of vampires to the world, terrorists and rival factions are plotting to assassinate Mina ?epe? before she has a chance to make her world-changing announcement.

(Note: The Special translated by Lust subs on 9/11/11 is actually a crossover special with Dance in the Vampire Bund and Asobi ni Iku yo! by KAMINO Okina)

(Note 2: Mina makes a guest appearance in Young Miss Holmes in The Adventure of the Sussex Vampire. The story takes place in the 19th century. You can see Mina and a few other characters drawn in a different style in the story and in the usual style by the usual artist in the afterword.)

Now that vampires have become an integral part of the Japanese economy and have proven that they are here to stay, they face a new threat. As the leader of the society of vampires, Mina Tepes must protect her subjects from their new enemy, God and all of his suicidal fanatics.
