The Angel Troupe consist of five members, the beautiful Milfeulle, Mint, Ranpha, Forte, and Vanilla. They have one mission, to protect Prince Shiva at all costs. Prince Shiva is the sole survivor of the royal family destroyed by a coup d'etat. They must complete the mission under the command of Takuto Meyers.

With their enemy right behind them, Takuto and the Angels have enough to worry about—but multiple love triangles don’t seem to be helping!
