Overview
Bulanawan and Aguio are twin sons of Langgona and his unnamed wife. At about two years old, Bulanawan is wrapped in wind-blown cotton and carried to a distant land, where he grows into a great warrior. When Aguio later approaches his wife without knowing their relationship, Bulanawan puts her inside his sleeve cuff and prepares to fight. The tale states this extraordinary concealment but gives no separate shrinking spell.
The twins fight until their weapons break and the earth trembles. Further relatives join the struggle, and even Langgona’s intervention provokes more fighting. Only Langgona’s father ends the conflict, after which the twins recognize their kinship. Cole’s note situates the story among remembered heroic exploits; it does not turn their world-shaking battle into a historical earthquake report.

- Langgona
Explicit opening parentage and the concluding recognition of Langgona’s father as the twins’ grandfather. The mother is Langgona’s unnamed wife, stated in the opening. Other arriving “brothers” are not assigned to this family because their exact kinship is unclear. This is not a merged genealogy of other Agyu traditions.
Aguio in Cole’s Bukidnon telling
Cole’s named telling identifies Bulanawan and Aguio as twins. Their fight ends with recognition; no identity with other Agyu epics is asserted.
Langgona, father in Cole’s Bukidnon telling
The opening names Langgona as father of both twins.
Langgona’s unnamed wife in Cole’s Bukidnon telling
The opening identifies the twins’ mother as Langgona’s wife. She is not personally named.
Bulanawan’s unnamed wife in Cole’s Bukidnon telling
The seaside episode explicitly identifies Bulanawan’s wife. Aguio’s attempted abduction does not create a second marriage.
