Panty Shots

Panty shots are the key trade that Yandere-chan can do with Info-chan. You take pictures of girl's panties with your phone, and send them to Info-chan in return for a favor.

If a student sees you taking panty shots, you will get a reputation penalty of -10. The penalty will keep stacking up everytime you're seen taking panty shots. If you apologize to them, you will get 50% off the penalty. If Senpai sees you taking panty shots, he will become disgusted, resulting in Yandere-chan becoming Heartbroken. If a teacher sees you, you'll get Expelled. Each panty shot is worth one credit toward favors.

Favors
These are the favours you can get from Info-chan (P.S = Panty Shots). Since the game is not complete yet, none of these favors can be asked. If you send Info-chan a panty shot from the same girl twice, it does not count as another credit toward favors. Info-chan will respond with a text message saying "I already have a picture of (student)'s panties. I don't need this shot."
 * 1) Damage rival reputation, 5 P.S
 * 2) Improve your reputation, 5 P.S
 * 3) Send student home, 10 P.S

The Dev has stated on his Twitter page that Yandere-Chan may be able to take panty shots of her own panties, however, this is still unconfirmed.

Trivia

 * If you are near a student and she might see you taking a Panty Shot, the "Visibly Lewd" warning will show up.
 * You can't get the "Visbly Lewd" screen when you're less 5 meters away from a student.
 * As of the August 18th build, Midori Gurin has unique green panties as opposed to the default white ones.
