Once upon a time, in a peaceful kingdom of white lilies, an opera singer named « Alice » met the crown prince after their recital in the royal opera house. The prince was returining to the castle after being raised away from everything since the loss of his parents, and had been sent to a countryside palace by order of his uncle, the Regent, to heal the trauma he had experienced. It was love at first sight between Alice and the prince. They shared a bond as they felt like outsiders from high society.
Suddenly, war breaks out: the monarch of the Northern Empire, the Red Roses one, seeks revenge on the kingdom of Lilies : the kingdom’s doctors were unable to save his younger sister from the same illness as their parents.
A fallen angel, sent by Archangels, delivers a message to a female knight of the Red Roses: « I will help you win this war » with a gift.
The Empire of the Roses sends its troops across the border, under the effect of the angel’s gift: a power that makes them invincible.
The angel betrays the empire by ripping out the Emperor’s heart, but he is resurrected by an Archangel, who gives him new powers.
With his new strength, the Emperor, returned from the dead, assaults the castle.
The Crown Prince of the Kingdom of the lilies dies protecting his soulmate, Alice, despite the help of his elite guard and Alice’s surprisingly good swordsmanship. The battle against the prince having weakened the emperor, he is forced to retreat.
Then begins Alice’s quest for revenge, as the Regent gives them a sword and a crown, as well as the mission to bring the prince back to life, at any cost.
