Are those... animal hairs?

Not just any animal.

There's a lingering youkai aura.

It's a youkai beast.

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

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

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

Can you look for these hairs' owner?

Just a second...

Okay. We have a reaction.

Seems promising.
