Yuyuhase is a male dunesfolk lalafell with blond hair and light yellow eyes. He is generally seen wearing the ultramarine uniform of the Crystal Braves.
He is chiefly preoccupied with accumulation of wealth.
Yuyuhase is among the initial recruits for Alphinaud's Crystal Braves, where he is distributed the ultramarine uniform during its inauguration. He is later seen during the search for the Harriers in Coerthas, where he gets in a skirmish with one of them outside Boulder Downs, allowing the Adventurer to follow a trail of blood to catch the heretic meeting with a shady merchant.
Riol begins to become suspicious of him and Ilberd when they begin telling contradictory stories about a shipment of black market weapons from a merchant involved in the unrest in Ul'dah, and warns the Adventurer of something not right within the Crystal Braves. These prediction would prove true as the Crystal Braves turn on the Scions and General Raubahn at the Sultana's banquet, with Yuyuhase's men holding Alphinaud at swordpoint.
Later, when the Adventurer, Alphinaud and Yugiri Mistwalker attempt to rescue Raubahn, who had been taken to Halatali for execution, Yuyuhase confronts them in battle alongside Ilberd and Laurentius. After being defeated, he flees.
