Soooo, finally got around to playing through the whole game with the True ending for the first time...
Spoiler for Spoilers True Ending/Marie:
So, turns out random Persona making once again saved the day.... as Masakado made fighting Ameno-sagiri a breeze.... while Satan with Black Viper/Mediarahan/Samarecarm made fighting Izanami/Izanami-no-Okami much, much easier. Though, honestly the final boss wasn't my favourite... that'd have to go to Kusumi-no-Okami. The design, and the shot of her with the giant eye in the background gave me goosebumps.... not to mention the BGM made it so much better~
All in all, next step is to beat Margaret on NG+
Honestly, it's the first actual Persona game I've beaten. I mean, I played through the PS2 version, but ended up stopping after abit. I won P3 FES.... but only got so far before stopping. Feels good to actually finish one~
