Persona 4
After defeating Izanami-no-Okami, Marie reveals that she is actually Izanami-no-Mikoto, a goddess who originally wished to both protect humanity and grant it's wishes, but as people changed and stopped wishing for truth, her wishes splintered into her and Izanami-no-Okami. With Kunino-sagiri, Ameno-sagiri, and Izanami-no-Okami fused with her, she becomes whole again and disappears from the Velvet Room. The true ending then plays out, with the game then skipping a few months after the last scene of the true ending (and after the events of "Persona 4 Arena Ultimax"), where the protagonist returns to Inaba for the summer. Upon exiting the train station, they discover that Namatame is running for mayor in order to atone for his previous actions. The protagonist will eventually meet up with his friends, who changed since the last time they all met, and will head to the Dojima household, where a surprise party was set up earlier by Dojima.
