The realm of Lusara is a land of splendor and strife, where towering kingdoms rise above fertile lands, and shadowed secrets dwell within the hearts of the powerful. The empire is upheld by a delicate balance: a sovereign monarch presiding over lesser lords, and beneath them, the two dominant Houses—House Avernal and House Crimsonvale.

These Houses are the empire’s shield and dagger, bound by duty yet divided by enmity. Known as the "Houses of the Devil," their reputations stem from the lords who rule them—individuals whose power, ambition, and ruthlessness have made them both revered and feared.

Each House serves the empire in its own way: House Avernal safeguards the northern frontiers, a land of unyielding mountains and winter's breath, while House Crimsonvale governs the southern expanses, a place of blazing sands and endless sunsets. Though their territories form the empire’s spine, their hostility toward each other threatens to tear it apart.

In a time of rising tensions, their paths converge not on the battlefield but at the edge of the empire, where an abandoned orphanage crumbles in solitude. There, among overgrown flowers and whispered memories, lives a girl who calls herself a flower. This meeting will set the threads of destiny spinning, entwining love, hatred, and the bittersweet fragility of life.
