Hibiki, I have a riddle.

Hmm? What is it?

What becomes harder the more H it becomes?

W-W-What are you saying, you perverted producer!

...Eh?! A pencil?!

No... I'm not that perverted...

E...? Ah, I got it!

It's a pencil! H is a measurement for the hardness of lead. H9 is harder than H2. So the more H the lead is, the harder it is.

What else would it be?

*pure*
