This is Rupin, a crafty salesman. During the day, he sells a variety of items at his Gear Shop in the bazaar.
Rupin is a merchant who operates the Gear Shop at the Bazaar in Skyward Sword. He lives with his mother Goselle in the southeastern part of Skyloft; he will buy certain treasures from Link if he visits Rupin's House at night.
When working his daytime job, Rupin appears as an energetic, smooth-talking and overbearing salesman; if Link decides not to buy an item he has expressed interest in, or if he leaves his stall without having made a purchase, Rupin is visibly disappointed at not having made a sale. When approached at night, however, he claims to tire of playing a "smiley shopkeeper", and claims that this is not the real him.
