She's a big believer of always trying to help others again and again, more and more. It's what she can do after all so why not do it?

"I can also help by giving a message to anyone at anywhere too! I've been around long enough to know the city like the back of my hand. Most of the time." Plus no one would find it suspicious to see a ghost here or there if they spot her. They always assume she's haunting that spot or something among those lines. "Er-- If they can notice me as well, of course."
