Eh... I'm not sure I get what you mean, Vasha.
Well, my old idea was basically:
-The intro takes place in Dasha's cave, preferably the same one in the real game. All eight of the chosen characters are there. *insert dialogue above*
Then that "one year and half ago" of the original intro, but it would read "10000 lightyears away" or something.
-Kardian would then inform them that the Quintessence was discovered by a high school student trying to find the cure to...cancer or cooties, you choose. For a science fair project. Each person is assigned a class with the girl who discovered it- Vikon is in Math with her, Serai in English, etc. Kardian is an Office Assistant who made sure of that. The game goes through a school day, English, Math, Lunch, etc, each class with a different QTBV character. A minigame should be in most of them if possible.
-Plot twists: The principal and vice principal are actually Agatha and General Dirk in disguise using the Quintessence. They discover that after school. Vikon accidentally loses the quintessence. And Dasha needs her iPhone.
-A second school day occurs. Here, Eshe finally manages to get the cure. But the Quintessence is still missing.
-It's the weekend. You, as the player, have to somehow find the lost Quintessence, avoid Agatha and the angry science fair student, and get Agatha's iPhone. You have Saturday and Sunday to do it.
-Possible multiple endings depending on what goals you achieve.
Eh, it's a crappy storyline anyways, but it's all I've got. I'd be happy to take your ideas instead, but I need a full plot idea.

Oh, and no matter what we choose, it has to have a school break-in and a school play/talent show. Non-negotiable.
