In the near future, in a nation unknown... Humanity has entered a new age where the majority are now Adepts- people who possess supernatural powers known as Septimas. Humans who do not have Septimas, known as Minos, are being hunted and executed by the Institute for the Promotion of Human Evolution Sumeragi.

It was a rumor of a warrior clad in pure white armor, accompanied by the Muse of Hope, Lola, who fought for the sake of all Minos.
