Plot[]
Out of the reach of the common citizen. Coupled with the decline in the values and morals of the Japanese people comes the emergence of a new type of Invader. No longer an alien entity, the Invaders can now absorb ordinary humans into their ranks.
Officially disbanded and discredited, the few remaining remnants of A.E.G.I.S have formed a clandestine network of operatives to hunt down and destroy the Invaders. The premier agent of what's left of the A.E.G.I.S Network is the antisocial Ayane who collects the crystal remains of Invader in exchange for money doled out by the mysterious Nanzo.
