Welcome back.

It's actually not Doppelganger, that's Goddess Ilias (2). You have to kill Alice during the story ending of Chapter 2. It's unfortunate but that's how it's done.

With Chapter 2 integrated into 3, Doppelganger is actually a white dot in the extra menu on the bottom of the screen, for whatever strange reason.
