If some unusual youkai has been moving around here recently, it's definitely worth looking into.

Are those... animal hairs?

There's a lingering youkai aura.

It's a youkai beast.

Okay. We have a reaction.

Not just any animal.

I told the mice to look for the smells of any unfamiliar humans or youkai.

Just a second...

Seems promising.

Can you look for these hairs' owner?

The fact that the scent and aura are still here means they have to be pretty fresh.
