"Everybody's been through the war and nobody deserves to through something like that again... people don't deserve that."
The great Academy of Cards starts another school year, and this time bringing two important personalities from the underworld. The youngest Princess of the White Kingdom, who despite not being next in line is loved by the entire kingdom and considered its greatest treasure. And the future Knave of the Kingdom of Hearts, the Knave is responsible for all the military power of the kingdom.
The pain of war is still present in the lives of both kingdoms. Still being driven by their old prejudices, but trying to make sure it doesn't happen again.
