Story

The King of the Flower Planet is dying, but his heir can't take up the throne until the legendary Seven Color Flower, symbol of the King's power, is found. The Angels Cateau and Noveau are sent to Earth to find the Flower Girl, a young female who descends from both humans and Flower Angels (who once inhabited Earth, long ago) - and they find Lunlun in France.
