mitsuru's persona lvl is surprising considering only 1 special uses it (outside supers), but the fact she only has 2 specials sorta evens it out I suppose...
also i seem to remember teddie's stats being perfectly equal in the original game (i'm struggling to remember), so I'm guessing they're graphs are meant to mimic the ones from the game, and thus their playstyles mimic them from the game, so it all adds up in a nicely I suppose.
