Jiburiru: The Devil Angel 3 Ep 1

Based on the erotic video game by Front Wing.

The peace following the previous story is short-lived, with a strange new photography student taking pornographic pictures of some of the students, something connected to the return of Misty May. When a more powerful monster than they've ever faced before attacks them, Hikari Jinno is abducted, and 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 is it too late already?
