Although it was like fighting 13 arcanas, defeating Nyx was easier than I thought. The persona abilities: "mind charge" and "salvation" really came in handy.
After defeating Nyx, Tartarus disintegrated and everything returned to normal. Everyone except Aigis seemed to have forgotten about the dark hour and their friendship. But during the graduation ceremony while Mitsuru was giving her valedictorian speech, she and the others remembered their promise. They all gathered at the school's rooftop.
It's been a while since I finished a game. I always look forward to the credits. It's like the trophy. Lol! :-)
Don't ever let the darkness take over your heart. :-) Happy September every one!!
