Rika glanced at him and smirked. She really, really liked that look on his face right now. 
"Oh, I so wanna know!", she chuckled as she heard her voice, albeit being a girl's voice, sounding so mean and vile. 
"You think we'll be the famous school pranksters again? Like we did in every other school we were in before?" 
At this point an idea popped up in Rika's head. 
"You know... I think we even have more ways of pranking... now that I'm a girl. Aaaaaand, since you're the genius of our duo, you can probably think of many ways to implement me" 
She smiled wickedly, but then faced him again. "So what was your idea?"
