"Look, Mr. Evil, I'm not having a good day today, got it? So I'd stop messing with people. Especially those in Mr. Matsumoto's class." Mr. Evil was still on the ground, holding himself but suddenly Mr. Evil himself turned into smoke. "A... A clone?" Aiko started looking around frantically, trying to find Mr. Evil."
"Well done, young girl. I wasn't expecting anyone to be able to do something like that. Now, how do you handle this!" A kunai was thrown at Riku, abd Aiko managed to run over and block it with one if her own just in time. This Mr. Evil was crazy.
Aiko pulled out an arm band and handed it to Riku. "Put it on. It'll give you ninja powers." She was going to need some help for this one.
