What about a room that continually blasts them with raw sewage unless they can answer true or false questions relating to the plot? For Example:

Computer: "The Syaoran in TRC is the son of the Syaoran in CCS, but is in love with the supposed AU version of his mother. True, or False?"

Random Student: "False! I'm in denial!"

Computer: "This unit refuses to accept your denial. Prepare to recive raw sewage."

*Shoots a stream of raw sewage at the student*

Random Student: Ahhhhh!

Since I completely forgot the contents of my old enrollment form, I think I should add some random character info (the first bit may or may not be in there) - can deal with (and may even like, depending on what the food in question is) eating about anything comprised of food, including Yuui's... eccentric... cooking, may or may not quote Dr. McNinja if appropriate, and has a tendency to point at people when raising any form of objection and yelling OBJECTION! loudly.

Good chapter. Ah, platonic love, my second most favorite kind of love - right next to love for one's family, of course. Yay for sakura tree similes, and as for detention... Writing perfect Japanese characters several times with blello ink in a spinning urple room?
