Cowgirl

Cowgirl (カウガール Kaugāru), not to be confused with Cow Girl, is an enemy and potential friend in Lust Friend.

Profile
''A succubus who acts as a "cowgirl", she's not a "Cow Girl". She seems to be acting as a cattle herder, but she moved to the desert from a rural village with few cows. The merchant Cowgirls act differently to the others.''

Strategy
To befriend Cowgirl, use Joke followed by "Impersonate Fess".

If you instead wish to defeat her, she is weak to Chest attacks.

Sidequest
Cowgirl is involved in a sidequest in Desire Village. In this village is a horse that is actually a cow according to the nearby Lookout Succubus, and which will give a you a Game Over if you talk to it. Talk to the "cow", then return and talk to the Lookout Succubus again and she'll ask you to find a Cowgirl to drive the "cow" somewhere else. If you've befriended Cowgirl, you can call her over and she will end up taking the "cow" away (or, as Fess points out, being taken away by the "cow").
