I have no idea who it could have been that broke the seal of Valefor.
From what I hear, it couldn't have been someone ordinary. It must have been someone extremely powerful, and that really worries me.

I know Valefor will try to steal anything and everything valuable, so maybe we can use what we know to catch him. Will you assist in finding some valuables?

There is a girl named Shumi in the Subway Entrance of Kerning City, and she doesn't know anything but money. She'll plead with anyone she sees walking by to find her missing coin!

If you go to her, she may have something that looks very valuable. Go see what she has.

Then must I go?

Hi! I'm Shumi. What brings you here?

Hmm, an item that looks valuable? Of course I have one.

But I can't give it to you for free.

Shumi is in Kerning City.
