Jiburiru: The Devil Angel 3

In line with the erotic video game by Front Wing.

The peace pursuing the previous story is brief-lived, having a strange new photography student taking pornographic photos of some of the students, something attached to the return of Misty May. Every time a better monster than they've ever faced before attacks them, Hikari Jinno is abducted, and also the New Angelic Gaia Interface is activated, in the form of a blue-haired virtual girl named Nagi... Can the N.A.G.I rescue Hikari... or perhaps is it far too late already?
