Hao's most loyal ally, Opacho was a malnourished baby in South Africa when Hao discovered her. In the English dub of the anime, Opacho is referred to as "he." Adopted and raised by Hao, Opacho follows him almost everywhere he goes. Hao often shares his plans, as well as thoughts about Yoh and his power, with Opacho.
Opacho possesses strong, albeit somewhat unrefined powers, including clairvoyance and the ability to project illusions. In the manga, she can also read minds. She is part of Hao's team (Hoshigumi) in the Shaman Tournament, though her attack power is never revealed.
Although Opacho remains loyal to Hao, near the end of the anime series, after Hao gains the Great Spirit's Power, she notices a change for the worse in him and decides to flee. Her last appearance in the anime is in episode 64, watching the destiny star fly by. She is one of the few survivors of Hoshigumi.
Opacho's spirit companion is named "Mama."
