Whoa! What was that sound?!

Did something explode just now?!

Hm? Mizuki, I didn't realize you were at school today.

R-Rui! That sound just now wasn't you, was it? What did you explode this time?

You're making it sound like I've done this before. My pneumatics experiment happened to carve a hole in the ground just now.

Yeah, that's called an explosion.

Also, Tsukasa's bangs got all singed this one time because of what you did.

Oh, no... That was more of a trigger malfunction as opposed to an explosion...

Kamishiro! Where's Kamishiro?!

You can tell the teacher all these excuses. Anyway, bye. I'd rather not be made an accessory to whatever you did.

But we're in the middle of a conversation. Aren't you interested in hearing exactly what I exploded?

Oh? Yes, I'm interested, but the teacher's right there... Rui, you knew, didn't you?!

What are you going on about?

Since we're here, I'll tell you all about it. Hehehe.
