Onyango, a retired Third Generation lieutenant of Special Fire Force Company 1, resumes active duty after Rekka Hoshimiya’s death. A Kenyan priest whose heritage shapes his identity, he presents as an elderly, bald figure adorned with temple-mounted metal cords and the signature high-collared cassock of Company 1 officers. Though age has tempered his physical prowess, he remains an operational asset, engaging in missions and promotional endeavors like the Firefighters’ Calendar. He shares a bond of mutual respect with Company 1’s captain, Leonard Burns, discerning the latter’s wariness toward Shinra Kusakabe’s recruitment. Onyango deflects Burns’ guilt over disrupting his retirement, emphasizing steadfast adherence to duty. Observing seismic anomalies tied to Burns’ degenerating right eye during the Netherworld crisis, he uncovers latent connections to the conflict’s larger stakes. In strategic operations, Onyango contributes to alliances like Company 1’s collaboration with Company 8 against the Preacher. His pragmatism surfaces when he permits Burns’ spirited sparring with Shinra without interference. Undaunted by critiques of his physique, he later assumes Rekha’s role in the Firefighters’ Calendar, training rigorously despite skepticism. Revived after Shinra Kusakabe’s temporal reconstruction of reality post-second Great Cataclysm, Onyango reaffirms his integral role in Company 1, though his post-revival activities lack elaboration. His past links to the Mari Kusakabe fire incident remain ambiguously defined. Balancing clerical obligations with firefighting, Onyango personifies Company 1’s fusion of faith and service. His decisions consistently prioritize organizational continuity and global stability, even as apocalyptic forces challenge both.
