Coronal Xhosa functions as the guide for the Urdr-Hunt competition. She formally presents herself to protagonist Wistario Afam only after confirming his eligibility, announcing his qualification with the phrase: "Congratulations. You are now eligible to participate in the 'Urdr Hunt'." Her demeanor remains consistently emotionless, displaying a complete absence of expressed feelings or visceral reactions even in dangerous circumstances. She maintains a soft, measured tone of voice at all times.

She appears early in the narrative, initially observed watching metallic debris fall from the sky near the Radonitsa Colony before her formal encounter with Wistario. Her face becomes visible to him during the activation sequence of his Gundam mobile suit. The name "Xhosa" is shared by multiple Urdr-Hunt guides operating across different factions, including Palstye Xhosa affiliated with Foundling, Batch Xhosa of the Omden Colony Company, Quential Xhosa with the Rakow Pirates, and Slice Xhosa among the Treasure Hunters. This recurring naming pattern and identical role suggest a potential systematic or manufactured origin for these guides.

Her personal catchphrase combines Latin and English: "Gratulatio! Congratulations," typically used during introductions. Narrative details regarding her origins, personal history, or character development beyond her function as a guide remain unexplored.
