Not a particular character in Mabinogi, just a player character wearing a Broad-brimmed Feather Hat (and other equipment I can't name off the top of my head).

@Ruiko, you're mistaken. That's an npc coming in g16s2 with bard update. Her name is Yvona

The update comes out this morning in a few hours.

Oh, ah well. Since the update's official now, tagging properly.
