The demons in my world come from a plane of existence known as the "Expanse"; which is what they call it here; we usually refer to it as the "Abyss" or "Makai". These demons are very much real, flesh and blood. So either we negotiate with them or fuse them. Certain demons are... rather impossible to obtain, however.

Persona can be obtained in many ways, and it usually depends on your context; all are conntected by the "Collective Unconsious". My method is the "Card Crush" method, as I had to face my own shadow.
However, other have a "Natural" method which is being given one to you by a being known as Philemon, or force it out with an "Evoker". Normally, Persona take the shape of the demons in my world, and although they are powerful... they barely compare to the real thing. So think of Persona as a way to enhance yourself.
[He would press one final button and a black vortex would appear behind him.]
And like Taylor said, no single weapon is better than others; but do keep in mind that some demons are weaker to bullets than to a blade. So find what you can use the most.
[The vortex would become 1s and 0s, taking the form of a beat-like demon of fur blue and silver, with three green eyes and armored parts.]
This is my partner, Pascal. he's a...special kind of Cerberus.
Hahah, I said a lot, didn't I? Did you understand all of it?
