Oopa, a young girl from Jananda, joined Tonari’s group after being sold by her parents for one silver coin. She possesses long dark hair and conceals her right eye beneath a bandanna, typically wearing a long-sleeved white shirt, yellow jacket, and tan pants. Like her comrades, she binds her right wrist with black cloth. Oopa fights using poisoned blow darts. Quiet, kind, and generous, she once secured cow’s blood to celebrate Fushi’s victory. Despite her gentleness, she fiercely threatened poison darts against anyone targeting Tonari. Oopa dreamed of uncovering the sun’s origin, a quest fulfilled after a battle against a Nokker. On Jananda Island, she aided efforts to shield Fushi from Hayase. Nokkers killed her during their assault. After death, Fushi inherited her form. He later adopted it to escape an iron prison, incapacitating guards with her darts. Oopa’s form persisted in Fushi’s transformations throughout ensuing conflicts.
