Minako (feMC) as Skyward Link

This one’s pretty straight forward. FeMC has a very bubbly and light-hearted personality, similar to the feel of Skyward Sword and its Link incarnation. She’s also the most expressive of the P3/P4 protags, just as Skyward Link is the most expressive of the console Links (though Twi is a close second). 

P3P also matches Skyward Sword in tone, especially compared with Minato’s side. The fact that Oct 4 can be prevented and there’s more room to get to know your dormmates, as well as a closer connection with everyone in general links Minako and Sky very closely, and both games deal with cleaning up the messes of those who came before. Also, the light-heartedness is broken up occasionally by nightmare-fuel in both games, so there’s that (the Silent Realm in SS and all the plots points in P3P).

Overall, I didn’t have to put quite as much thought into choosing her as I did some of these others, so this explanation is pretty short.
