Years of war have tired both the Poison Fangs and Razor Fangs, endless bloodshed that stained even the blackest of nights crimson. When the famed 'Cold blooded' Prince is crowned King, he proposes peace ... and marriage to eldest daughter of the Razor Fang lineage, Princess Leona. If they refuse? Every citizen in their kingdom will be slaughtered. Unfortunately, after the Razor Fang King agrees, Princess Leona runs away, dooming the kingdom to a painful death. Ayane, the illegitimate sixth Princess of the King, is tasked with finding her so that the alliance can be completed before their people are wiped out. However, when she finds the 'Cold blooded' King first, the temporary peace that was established hangs in a precarious balance as Ayane strives to find Leona without pissing him off. Or, she's dead.
