although I think its funny, there needs to be a Cap. somewhere.
here's screenshot of non cheated gameplay
Orihime (25%), Misty (10%) & Darkness (15%) give % based exp with no cap
And upgrades seem to go infinite (Rare probability = 690% lol)
strat: unlock Orihime and get her event, then clear way with bombs until you get to an event space rince and repeat.
