If no one but you saw him, he might not have been a regular person.

If it was a youkai, the options are endless.

But that would mean they're hiding in the Village, wouldn't it?

If they see some benefit in doing so, then why not?

For example, it's not like Suzunaan only stocks imported books, does it?

I take full inventory every six months, but I make almost no mistakes.

"Almost" means there are still some, doesn't it?

Well, you know... buying books causes its own expenses...

And they wear out in use, so they also need repairs, right?

Uwaah... Sounds like sloppy accounting.

Can't be helped, can it? Books are still so expensive. But anyway, it's a bit scary that some youkai could come in with me none the wiser...

I doubt any youkai stole from you, though.

Intelligent youkai seem to find stealing shameful, just like humans do. They're likely to pay the full price.

And on the other hand, unintelligent youkai probably don't have interest in books. ...Fairies are just out of the question.

Apart from that, it could just be a miscalculation, or a customer behind on their fees.

Yes, it... might've been a customer.
