A) "We wait for Chiyoko to give that big speech next Wednesday to the assembled Practical Joke Clubs of Japan. Before the speech, we find some clever stratagem to finagle her out of her panties and some hapless pervert to blame the theft on. Meanwhile, we start a rumour among the audience that our club is going nopan for some humorous yet semi-believable reason. Thus, when the concealed leafblower inverts her skirt before the bustling crowd and reveals her pantiless status to all and sundry, there'll be no clues pointing to us."
B) "Superglue in her shampoo, itching powder in her body lotion. Her hands are stuck in her hair, so she can't dress or cover herself, and she has a burning desire to rub herself sensually all over everything that moves. After that I don't know what we do with her, but maybe we can get her out of the shower room and into a public space.
C) "She has a favorite icecream parlour in the Hadaka Arcade. If we could manage to strip her naked there, she'd have to run through the whole shopping district in order to get somewhere safe. Also we could cover her in hot fudge and whipped cream, if you're into that. It's okay if you aren't. I am though."
"You're into covering girls in hot fudge?" asks Mami, hesitantly.
You blush and look away. "O-of course not," you stammer. "I just meant in, you know, a revenge kind of way. Anyway, enough about me. There's still some stuff we need to figure out, and I had a few questions I wanted to ask you..."
(Which is to say, if you had any further questions about what's going on, fire away. Mami will answer to the best of her ability.)
