Jonathan Fifi'i (c. 1921-1989) was a Kwaio leader, a principal organiser of the post-war Maasina Rule movement on Malaita, and later a district figure whose autobiography, recorded with Roger Keesing, is a central document of Kwaio life. Though drawn toward the wider colonial and Christian world, he remained a defender of Kwaio custom and of the ancestral religion, and his account preserves much of the traditional knowledge of adalo, taboo and sacrifice. In Kwaio belief he too becomes, at death, one of the adalo who watch over and afflict the living.
