It's not a girl, it's a crow on the top of the tree in that place ;)
He'll ask you for various stuff, he's a list of what you can exchange with him: http://demonssouls.wikidot.com/crow
My suggestion is that you trade the Gold Mask (found on 3-2) and the Talisman of God (You should have found one in 4-1, else you can buy them from the vendor in world 5) for two Colourless Demon Souls.
In order to exchange, you'll have to drop the necessary item in the ground on front of the tree, then go to the menu and load your profile. After doing that, you'll find the treasure behind a root on the right side of the tree.
