Betrayal by a rogue agent has rocked the Vampire Bund hard, especially Akira. Even worse, the agent has stolen the most damaging secret that Princess Mina tried hardest to conceal-namely, that Mina has the ability to transform into a full-grown woman capable of bearing children. With this news leaked to the lords of the three great vampire clans, the brazen Lord Ivanovic launches an all-out assualt on the Bund in order to claim Mina for himself. Princess Mina is left no choice but to counter-attack, as her once idyllic haven for vampires is turned into a war zone with massive casualties on both sides.
