Coronal Xhosa is a mysterious girl who appears before the protagonist Wistario Afam, claiming to be the guide to the Urdr-Hunt. Her role is to oversee the competition, and she formally confirms a participant's eligibility, announcing to Wistario, "Congratulations. You are now qualified to take part in the 'Urdr Hunt'".

In terms of personality, Xhosa is characterized by her proper and polite manners, speaking with a calm and gentle tone that belies her apparent age. She rarely changes her expression, making it difficult to discern her emotions, and she remains consistently devoid of any emotional or instinctual reaction, even when faced with dangerous situations. She has a personal liking for brewing tea.

Xhosa appears early in the story, first observed watching metallic debris falling from the sky near the Radonitsa colony before she formally encounters Wistario. Her face becomes visible to him during the activation sequence of his Gundam mobile suit. The name Xhosa is shared by several other guides who serve different factions within the Urdr-Hunt, including Palstye Xhosa of Foundling, Batch Xhosa of the Omden Colony Company, Quential Xhosa of the Rakow Pirates, and Slice Xhosa among the Treasure Hunters. This recurring naming pattern and identical role suggest a possible systematic or artificial origin for these guides. A personal slogan often used by her when making introductions is "Gratulatio! Congratulations". Narrative details regarding her personal history, deeper motivations, or any character development beyond her function as a guide remain un explored. No notable abilities are documented beyond her function as a guide to the Urdr-Hunt.
