"It is the near future, and a new population of people known as "adepts" are being born with supernatural abilities known as "septima."

Gunvolt, having put a stop to the Sumeragi Group's plan to control all the world's adepts known as the "Diva Project", has begun to heal both his body and mind from the deep wounds caused by that incident....

However, the passage of time does not always allow warriors scarred by battle to truely relax.

Enter "Eden", a group of superpowerful adepts from all corners of the globe.

Now, Gunvolt and Copen must stand up and face a new threat."
