My rogue is a vaguely asian looking female human, so I named her Mikazuki, which is a JP name and a sword in FFXI. I believe it means 'crescent'
When I changed realms, it was taken, so now she's named Satsuki, which is also a JP name. Satsuki is also, I guess, an old JP word for the 5th month of the year (may).

"A fine day in May is called "satsuki-bare." Yayoi and satsuki can be used as female names. "
