This is betetr seen in video, since the credits include images that finalize some of the details. And I did not screen capture them because I am lazy.
The ending! And credits (viddler)
Almost over here, folks (youtube)
Once the true form of the Soulless God has been defeated, this happens.
It blows up. Into lasers. LASERS.
And then the stability of the Akarana Corridor is compromised, maybe he did manage to change time... (He did, the Persona games happen in the same world, so he somehow averted the Apocalypse)
As one can see, the Future Raidou refuses to let go. If he is going to go down, he is taking her with him.
Raidou is the hero. He gets the girl.
Back to the bridge. THey are back, safe and sound in their own time.
She is just being silly.
That he did.
The sun rises, and everything is fine now.
... The Next day.
He doesn't believe either Raidou?
It's their job to keep the Capital safe.
And so ends this game.
But it is not over yet! No sir!
In the next page, one shall met... RAIHO!
Next page. (Give me time to grind to level 30, damnit!)
