There’s a good page on the wiki about this:

So you want high ego, high offence, and a lower defence. The higher ego means you can afford to lose more ego before having to use Smileprins or whatever, and the less ego you have, the more powerful your attacks.

Here’s my stats if they help, these seem to work pretty well for me:

Max ego: 145

Tears: 208

Offense: 18

Defense: 11

Luck: 4

Frugality: 6

Charisma: 3

Upkeep: 3
