Yumi first appeared in Band of Thieves as the leader of a group of mercenaries hired by Nisovin. She is a quick witted greedy character who does not seem to care much for safety of those she works alongside. Yumi was last seen in URealms Live fleeing a small Elven village after her attempt to steal Gwyneth Sunsword's Sun Key from a group of sunclerics ended in failure.
