The Rainbow Fantasy Era

In the year 45000 of the Magic Era, countless races lived together on the vast, fantastical continent of magic. Elves, dwarves, butterfly fairies, giants, angels, dragons, and humans had made their homes there for generations. Each race had its own territory, and they left one another in peace, maintaining a golden age that had lasted for millions of years.

But the sudden arrival of the Dark Clan shattered the world's tranquility. Their eerie dark magic corrupted the continent's inhabitants. Countless weaker races were bewitched by inner demons and had their powers assimilated, turning traitor and joining the forces of darkness. A magical war engulfing the entire continent erupted without warning. Flames of war spread in every direction, and its people were driven from their homes.

Amid the chaos, only the four great cities of Elven Garden, Rainbow City, Sky City, and the Eternal Night Empire held their ground, protected by supreme barriers and the accumulated strength of their races. To end the endless war, cleanse the dark magic, and restore order to the continent, the leaders of the four cities joined with the chiefs of the dragons, dwarves, and giants for a summit in Rainbow City to save the world.

Vivian, the cheerful and courageous sixteen-year-old sixth princess of Rainbow City; Lilith, the composed and perceptive sixth princess of Elven Garden; Annabella, the bold and carefree fifth princess of Sky City; and Kailaviel, the resourceful seventh princess of the Eternal Night Empire: four girls from vastly different backgrounds, with complementary personalities, were entrusted with a mission in the hour of crisis.

From that moment on, the four gifted girls journeyed side by side across the vast continent, traversing the territories of countless races and rallying the forces of justice to face the surging darkness. Through battle after bloody battle and growth after hardship, they shattered the dark conspiracy, protected the peoples of every race, and forged a grand, rousing epic of salvation.
