When you start ppa, you click "items" and it will show there. If it doesn't, you don't have a kini. If you go into your profile and go down to items and it shows there however, email ata and include your name, game you play (pimd), and your issue. I don't know the email by heart. Sorry. Edit: support@athinkingape.com
Or... If you have an updated version of the app, click the help button and scroll down until you see the email us option and you can email support straight from the app. But yes, cat cafe pays the most and pizza pop the second most.
I guess the next are pro parties, but most clubs you have to be 500kcs or above before allowed to merc for a pro. You start to get more successful hits when you're 100kcs or above. Good luck.
