On a continent ruled by chaos, the Lords have the power of a holy seal that can calm the chaos and protect the people. However, before anyone realizes it, the rulers cast aside their creed of purifying the chaos, and instead start to fight each other for each others' holy seals to gain dominion over one another. Shiruka, an isolated mage who scorns the Lords for abandoning their creed, and a wandering knight named Theo, who is on a journey to train to one day liberate his hometown, make an everlasting oath to work together to reform this continent dominated by wars and chaos.

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!
