At the end of the airing of the final episode, an unaired episode of Persona 4 The Animation was announced to be released in the tenth volume of the Blu-ray & DVD. It will be the true end episode titled "No One is Alone" and will be released on August 22nd.
They don't really have enough time to put in the true ending anyway. Sure you could argue that they could chip away some time here and there, but I doubt that would be enough. At least it'll be animated properly and not rushed to try to squeeze into the 25 eps.
YEEESSS!!! I read the news on the train, and I was about to squeal like a fangirl and embarrass myself in front of my friends and a bunch of random passengers. xD Though it was kind of expected that they would have a secret extra episode, since they weren't doing the true ending in the TV anime...... I was hoping it would be an OVA though, so it wouldn't have time constraints...... ah well, at least it's getting animated. ^^
Sigh.... I can't wait for this episode...... It's getting released a day after my birthday! x3
