Make sure you've done everything though.reached the end of the current build. Very Cool. I wonder how absorbing the demons will affect Aura. Mental Guide Aura still gives me creepy vibe like she is more of an entity posing as Aura self. Or Perhaps its Aura True self locked a way deep in her sub conscious waiting to be set free.
There are multiple ways to reach "end of current build" and be sent to the CG/NG+ room.
