|Cocobuki and his brothers were members of the Order of Nald'thal under Mumuepo and attained their position during the Calamity. When the former guildmaster responded with violence to rioters seeking aid, Cocobuki, his siblings, Pipin, and Papashan were the only ones to step up and aid Nanamo Ul Namo in keeping the peace. The five replaced Mumuepo after he was arrested for other crimes. 
He cares deeply for his younger brothers, particularly Cocobusi, whose innate inability to become a thaumaturge and join his siblings has long troubled him.  Despite the teachings of his craft, he is willing to sacrifice his own life to save the people he loves. 
His empathy does not extend solely to his siblings, however, as he shows care and concern for the well-being of his guild members overall. When Yayake is accused of aiding Mumuepo in a plot against the sultanate, he shows understanding for her emotions and takes an impartial stance. He ultimately believes her innocence at her word, and offers her a way to benefit the guild and atone for the mistakes she made. 
Cocobuki is knowledgeable on the War of the Sisters. He notes that Amalj'aa warriors aided Ul'dahn forces during the conflict with Sil'dih, and that this information was hidden from most historical texts. This leads him to ponder whether someone considered this information "inconvenient" and whether other facts may have been similarly buried. 
During operation Rhalgr's Beacon, Cocobuki and his brothers blasted open the gates of Ala Mhigo, allowing the Eorzean Alliance to liberate the city-state.
