Seven Seas Entertainment is expanding upon its Dance in the Vampire Blund license with the release of two collections of material originally produced for Comiket, the biannual doujinshi fair in Tokyo.

Available for the first time to the general public, Dance in the Vampire Bund: Forgotten Tales and Dance in the Vampire Bund: Secret Chronicles include what the publisher bills as "lost material" from series creator Nozomu Tamaki, containing "brand-new artwork and sides stories that expand the mythos like never before."

Dance in the Vampire Bund centers on Mina Tepeş, princess-ruler of all vampires, who ends centuries of isolation for her kind with the creation of the Bund, a special district for vampires off the coast of Japan.

Arriving in June, the 192-page Forgotten Tales includes previously uncollected manga, plus bonus material. Secret Chronicles, meanwhile,features 280 pages of previously unpublished canonical short stories from Tamaki himself, plus more bonus material. It's scheduled for release in October.
