Hey there!  I'm always up for a Persona RP. 

 However, (and I know it's probably rude to argue something like this right off but)  I disagree with the human durability part.  I always figured that part of having a Persona is that it grants you these sorts of resistances.  There're these cool scenes in the Persona 1 manga, one where a character gets hit by a fireball and initially starts freaking out before realising that while she's hurt, she's not lit-on-fire hurt, whereas in another scene where a different character gets hit by an attack and is genuinely seriously injured and would have probably died because he didn't actually have a Persona.  I'm not saying I won't join if you don't change it.  These are just my thoughts.  I think it would be very limiting if our characters were constantly having to worry about major injuries and the like from what should be a relatively weak attack (like a basic fire spell).
