Lono hears a voice in the house that tells him to stay in the yard. Mungan refuses the offer; she says she has become whole once more. Mungan, to reciprocate the gesture, gives Lono betel nut and young rice to distribute among the people.Lono returns to Pinamatun and tells Agyu Mungan is immortal, having eaten golden betel nut and golden rice.There is no single standard narrative for the sengedurug nor limit to the number of stories that can be told; hence, the multiplicity of Agyu stories.As early as 1913, Fay Cooper Cole published stories of Agyu, which he described as a “bedtime chant.” Tranquilino Sitoy of Misamis Oriental discovered another Agyu song and published it in English in 1937. Arsenio Manuel transcribed the epic and entitled it Agyu: The Ilianon Epic of Mindanao.
Agyu has four sisters, but only Yambungan and Ikwangan are mentioned in the Manuel version.Assisted by Batooy Ambag, a son- in-law of a datu, and Pilisianu Tisio, Manuel recorded the epic from 21 November to 25 November 1963.Blagtas Pandakan learned the epic from his uncle Sugalan, who had learned it from his father, Ampalid. Living in the country of Ayuman are the heroes Vanlak/Banlak, Agyu, and Kuyasu. Agyu is the epic of the Arakan-Arumanen or the Ilianon of northern Cotabato in Mindanao.
