In your guys opinion, which personality is the best one?
For a physical attacker (High attack, moves mostly have a fist in front of them):
Attack +, Technique - : Airhead (For maximum damage potential or if their exposure is so low there's no point in boosting it)
Exposure +, Technique - : Meathead (If you want to make sure they hit first, they should already have good exposure though)
For a Tech/Special attacker (High tech, moves mostly have a blue orb in front of them):
Technique +, Attack - : Slut (For maximum damage potential or if their exposure is so low there's no point in boosting it)
Exposure +, Attack - : Clumsy (If you want to make sure they hit first, they should already have good exposure though)
Probably Airhead (Physical)/Slut (Special/Tech) are the safe bets for damage dealers. I highly recommend you don't go with any personalities that drop defense in favor of damage. This game punishes stuff like that heavily. Sad, Determined, Lil' Devil, Orgy Lover, can be pretty dangerous.
For a tank, you could go any of the following:
Defense +, Attack - : Masochist (If you don't care about their damage at all or they have some Tech damage potential)
Defense +, Technique - : Otaku (If you don't care about their damage at all or they have some Attack damage potential)
Lewdness +, Attack - : Heroic (If you don't care about their damage at all or they have some Tech damage potential)
Lewdness +, Technique - : Seducer (If you don't care about their damage at all or they have some Attack damage potential)
Defense +, Exposure - : Timid (If they already have extremely low speed or you want them to be able to deal some damage)
Lewdness +, Exposure - : Pervert (If they already have extremely low speed or you want them to be able to deal some damage)
The tank ones are trickier because you have to decide which between lewd and defense to boost. Probably boost what the girl is already best at so it's a bigger bonus. A girl with high defense should probably go Masochist or Otaku for example.
If you have a highly hybrid girl, meaning all her stats are pretty even and both types of damage moves you want to keep/use, you could consider Self-Love as well. No boosts or penalties.
