ones that are sexully empowered/less shy are definitely going to have the most fun in this game, or at least if you app a shyer one, use and get creative about the incentives for them to have sex and get involved

a character that doesn't look like they're in their early teens is also going to help. i haven't tagged several of our girls in a smutty way just because animanga lady art is so boner-killing. stick to someone who actually looks like a woman and isn't fetishized for her ~youthful~ appearance.
