well, there are Artificial Persona Users

But no artificial persona's?

There is Lavrys and Aigis who has aconduit to summoning personas.

the Personas themselves are 'real' but
they dont have a way of summoning their personas naturally so
artificial persona users

closest you could get are the androids but technically speaking they are artificial, not so much the persona

Okay

Nope no such thing but I kinda count sho minazuki for this
