The Shinigami King had twelve daughters, one born in each month. The bearers of the children were the stars themselves, manifestations of the constellations in Shinigami form. The eldest was Ayra, created in early April. When Ryuk and Light are bending all the rules, Ayra is sent to find some way to condemn them, find some law they've been breaking of the Shinigami's. Never having been in the human world before, Ayra is in for one hell of a ride.
