In the kingdom known as "White Rose" there lay a peaceful yet lively city, full of life and beauty.

The day had come where the king and queen had to decide who would be the best suited to lead the kingdom in their passing.
Among them 6 chosen "prince's" and "Princess's", only known as a crown title rather than actual relations to the royal family, most times.

The chosen prince's and princess's called were Almond of the red rose, Victor of the black rose, Shadow of the white rose, Elaine of the blue rose, Evaine of the purple rose and Iris of the green rose.

The 6 chosen potential crowns were tasked with proving their worth by interacting among the citizens to see who was best suited to lead the kingdom, the one best suited would be named "Rozen", also known as "The Chosen Rose" and as such whichever rose they represent would become the kingdoms rose name.

However fate would have the chosen crowns to prove themselves another way, as the goddess of existence, Siami, calls out to the kingdom, pleading for their help to defeat the demon of the nothing, Nyn, for it was foretold that Nyn would be released from his prison within the blank abyss where he lay trapped since the dawn of time.

With Nyn's return the abysmal creatures will be released unto the realm of existence and the gates of the blank abyss will open, letting each abysmal creature infect and decay all in their path.

With this calling from the goddess of existence herself, Siami, the chosen crowns take up arms to defeat Nyn not only for the crown, but for the continuation of existence itself.
