I didn't think twice when Arminillo asked for Stefl's name, because he wants to confirm if the ability matches up with the character.. I just assumed he forgot that Stefl name claimed a while back
But, now that I think about this, I feel that this is actually a slip from Arminillo. I've been suspecting him beginning with the odd time limit vote and the miz vote. He agrees that he only voted for Trucks/Miz/Stefl because of just jumping on the bandwagon which is pretty suspicious.
Now, to the name claim. I haven't played the Persona games so I'm not too familiar with the series, but I have been wondering how the teams would be built around. Main characters are town, so who are the mafia? Luckily I did watch P4 Animation so I did see the bosses that they fight, which are Personas. They fight those Personas before the main characters can control them for their own.

Arminillo specifically asks Stefl what his persona is, rather than the character, because I believe that Arminillo got a Persona character and assumed that everyone else will too, which is not the case. So if this is indeed Main Characters vs Personas, Arminillo has a really high chance of being a Mafia
