It is highly recommended to play this version first!
Or you can watch Nicob's Let's Play of Princess Princess over here!
Or formerly known as Princess Princess V6. There were some change in plans on how the final project would look/start etc. So this defunct chapter is not usable anymore but it's still plot important.
So here you go! I still recommend you play the original PrinPrin then play this. Since you know, connected and all or some things won't make sense at all. There's also some freebies for defeating the final boss of the game that can be used for your game projects. Will you reign supreme?!
We hope you enjoy the game!
