Geise H. Huguest is a character in the Earth Federation's Investigation Bureau. He holds the rank of director and is depicted as a capable and excellent agent, though his posting to the remote region of Davao suggests he may be somewhat removed from the central hubs of political power. A key part of his professional role involves conducting hearings and gathering testimony.

In the story, Huguest is assigned to question Hathaway Noa following a dramatic incident aboard a hijacked shuttle, where Hathaway played an active role in subduing the terrorists. After the passengers are secured, Huguest and his colleagues from the bureau rendezvous with other officials at the airport lobby. He is responsible for the official investigation into the hijacking, taking Hathaway away from the crowd of grateful passengers to a more formal setting for an interview. In a subsequent development, his office arranges for a car to be sent to Hathaway's hotel suite the following morning to bring him in for further questioning.

No information is available regarding his personal background, personality traits, internal motivations, or any significant character development over the course of the narrative. His key relationships, aside from his professional capacity as an investigator, are also not detailed. There is no information about any notable abilities he may possess, whether in combat, piloting mobile suits, or other specialized skills.
