How do you best slaughter a Persona 3 fighter? Hitting a weakness does it quite nicely, and Guy just so happens to have a holy sword on hand for the task. And oh look, Koromaru is weak to holy attacks! Bad news for the little doggy, as Guy's physical is fearsome even before it hits a crippling weak point. Maxim's friend and steady swordsman is as tough as they come, being a match for Koro in toughness even before his healing IPs and protective skills are put in place. Guy's warrior spirit means he doesn't have the usual fighter's problem with status attacks either, meaning Koro can't get around Guy's overwhelming strength.
