Lusunzi is a major spirit of the Woyo kingdom of Ngoyo, within the coastal Kongo cultural sphere. In the tradition recorded by Jan Knappert, Lusunzi is a water spirit born to the rain goddess Bunzi, and his periodic visits to his mother bring the kalema, the spring tide, into the estuary of the Congo. The missionary-ethnographer Constant Tastevin, whose 1934 notes underpin Zdenka Volavka's monograph, names Lusunsi as one of the three principal tutelary spirits of Ngoyo alongside Bunsi and Kanga, and describes the plaited brass-wire 'fishing basket of Lusunzi' that formed the dome of the royal shrine; Volavka's book reconstructs this shrine and the investiture rituals attached to it. The sources differ over the spirit's sex, Knappert making Lusunzi a son of Bunzi while Tastevin's notes speak of the basket that served Lusunzi to collect manioc in the fields of 'her' subjects, so it is recorded here as undetermined.
