Knowledge, mysteries, and power. A group of youngsters are summoned by a figure titled "The Overseer", a mysterious man who strips them of their normal lives as teenagers. Inside his castle, gleamed by the brilliance of countless stars that dance around it as they flow in the cosmos, he sets them on a quest with these words:

"You've been invited to a world, not of your own. Why? With this opportunity that I've given to you, that is a reason you will seek for yourselves. Only when you've found knowledge will you find the truth. May your journey bring good fortune, children of another world"

To this world with his grand words, now will they confront their new challenges ahead, in a world filled with magic, unique personalities that share this world of fantasy, and many questions and obstacles that lie ahead.

As beginners of a journey that was set upon like destiny.

Into the new world.
