Solving your troubles, one way or another.
A mysterious man in a maid outfit who appears and disappears like a ghost.
He listens to people's requests and vanishes without accepting a reward. Rumors label him a "handyman," "informant," "detective," or "unemployed," but he neither denies nor confirms them.
Everyone who knows him says the same thing:

Every time he's asked why he wears a maid outfit, the answer changes.
"An ex-girlfriend's hobby." "A penalty game." "A uniform." "Mourning clothes." "...Well, which do you think?"
However, there is one thing everyone agrees on.

Don't go digging into my secrets, okay?
