In a world unknown to humans, vampires, demons and angels rule. This world is split into four clans: Usotsuki, Rei, Kuronokirako and Airenisa. After a war broke out between the four clans many years ago, the King and Queen of the Usotsuki Clan were killed, orphaning their two children: Princess Misaki and Prince Kanon. Years later, the war is still raging, and the lost and broken children of the dead rulers of the four clans find themselves trapped in a battle for superiority, whilst still protecting those dear to them. Sucky summary, hopefully good comic. Yaoi, het, yuri, full warnings inside.
