The Nafana (some of whom refer to themselves as "Kalango") live on either side of the central western border of Ghana and the Côte d'Ivoire. The large plank masks, bedu, are danced during zçrçnyep, the last month of the Nafana year of twelve months, when they appear nearly every night in the village, either to dance on the central square or to visit compounds.

The masks perform benevolent rites towards communal purification, absorbing evil, misfortune, and other difficulties. Made from the silk-cotton tree, onyina, and worn with a long shaggy raffia costume, they are bathed once a week during the month of the dance and at the last they are recoloured with charcoal, bidie, and kaolin, hyire, mixed with shea butter. Between the dances they are stored in a special room leaning against the wall, and, for the remainder of the year, in the rafters, face down. The male masks are between 7ft and 9ft, the female between 9ft and 11ft: although they appear together in public they never dance at the same time, to the three types of drums: the male, blac, the female, tsulc, and pinge. The dance is more fully described by Williams (1968, pp.18-21) and also mentioned by Bravmann (1974, p.106-118).
