With more and more Red Helixes turning up missing or dead, the Shadow Ravens are ready to take their fight to Doctor Nagi himself.

But breaking into Alpha Citadel is no cakewalk, and Quanta isn't so sure about this whole "teamwork" thing.

If she and the Ravens can't learn to work together, no amount of rewinding time will save them from the inevitable.

And if the Seligo win, everyone loses.
