Hmm.

Aren't these tengu letters?

A pretty recent work.

I knew it!

I knew I'd seen 'em somewhere.

But the contents are just regular scribbles.

Where'd you find this?

Are you saying you don't know?

Heheh...

What's so funny?

If you think I wrote this, you're way off.

Sloppy letters like these...

Indeed... Someone who doesn't write them regularly.

Perhaps...

Someone whose tengu letters were copied and 'learned by imitation'.
