"Well, before arrivin' here, I was on this big quest to save the universe. Since I finished it, I thought I might use it fer the chance to relax, take a break... y'know, vacation."

But as she said... she's not happy unless she's busy. Just lying around in the sun is boring to her, not relaxing.

"Now as fer what ya can do fer me in return... well, y'know those concrete pathways in the mountain? Those are partly my doin', and I've got more ideas on projects ta improve this place. Could definitely use more hands if I decide to implement 'em."

So yes, that's what she wants in return. Manual labor. To be fair, she doesn't know what Haru's skills are besides shooting.
