Name: Suirieko Mizukoshi
Server: Lamia
Zone: Mist, Ward 7, Plot 20 (small)
Frequency: Always (considering it's the name of the NPC)
NPC Name: "Merchant & Mender" I'm PRETTY sure it's supposed to be called Junkmonger.
Also, it's female Au Ra.
Location: Private Cottage - Most (6.1, 6.1)

Just look at the screenshot: I'm pretty sure she's supposed to be called Junkmonger, and not Merchant and Mender (Especially since she doesn't repair).
