Kawaii Klub

This was a PSP game, that you can actually play using PPSSPP, although the text I believe is in Japanese, it's still a fun game to play when you're bored.

You can play as one of several characters from the series, and even I believe you can play head to head with another player!  I'll see if I can find some translated instructions.

Note, I've finally managed to add this game's ISO to the Downloads area!
