Okay? Did you actually read the first comment I replied to? It was in the context of people saying that "it doesn't make sense", which I tied into the fact that Yukiko actually fights in P4 and Rise does not, thus Yukiko would be a playable character in P4A with basis, especially with plenty of skills and animations to use as a reference while Rise had none and they essentially had to start from scratch, with the sole concepts of music and analysis to use as fundamental points.
Like I said, I'm not arguing that Rise as a fighter doesn't make sense. That is not my stance here, so I'm not sure what you're trying to achieve by telling me the above.
Additionally, I'm going to cite Tatsuya's EP scenario again for reasons as to why Persona users are able to fight.
