Killing monsters and saving people from them is fine, and fun too, but taking a break to help a friend out with her business is a nice change.

Often works in the Icenfar Howling Wind
Sometimes at Ace Rentals, #8 Ackalia.

if she's busy whacking monsters:
Or if her location is hidden:
She probably won't

If she's in the Tymorean Temple:
She definitely might

If she's working in Icenfar:
She will, bring your money pouch

If she's filling in at Ace Rentals:
She probably already has today
at least once, but you could be next

If you need more of a description:
Look at the portrait for awhile.

There are some things she won't do
Find them out for yourself

When she gets ready to work, she quietly sings the chorus of a catchy tune with a little giggle at the "But I do...":

When she isn't working, she still does, but she only has to do what she wants to and chooses who she does it with.
