<In a bookstore>

Kirino: Shindou-san, I'm going to buy a pair of scissors, mind waiting for me?

Shindou: Sure Kirino-kun, I'll wait.

Kirino: Great! *goes to the scissors section and takes a pair of scissors* Hmm...

Shindou: You're gonna buy that?

Kirino: Lemme test it first-- *cuts a strand of his hair* Yea, its sharp, but not sharp enough...

Shindou: *very shook* Hey Kirino, I don't think you should do that-

Kirino: *keeps testing each scissor available with the same method*

N/A: And so... This is how Kirino's hair turned short and shock the hell out of Kariya and Shindou. Remember kids, scissors are sharp.
