Two feuding clans both produce heirs to the long fought over crown, which naturally makes them hate each other all the more. Princess Kurriyuki finds Prince Daiki to be a power ally. Sadly, it doesn't look like friendship is gonna mend old wounds- neither would the fact that Kurriyuki's advisor locked Daiki up in prison after saving the princess's life.... But, maybe the fact that said advisor and her twin sister are trying to awake the Deciever would be a prime example of when to put differences aside to prevent the End? Only one thing is for sure: "There shall be blood".
