I came up with a persona character (see Fukushu Makoto) that's has its own spinoff titled Fukushu Makoto that can be connected to the main games about a future protagonist having its own origin story before the events of the main game. Interested?
I have my own version of Persona 4 that has my friend as the main protagonist
The first Persona is actually where all the events start happening. Everything gets a "reset" in the Persona 2s as well.
What do you think?
