TV-Series
Description
Robert Chase operates in the First Unit of Dorothea, a peacekeeping force dedicated to suppressing illegal fairy activities in the postwar world. He possesses dark short hair, wears glasses, and is typically seen in the standard Dorothea uniform.

His background lies in the military and later the Security Bureau, transferring to Dorothea after the continent's unification war. This internal affairs history fosters a professional distance with colleagues, who primarily address him by his surname. An instance where Marlya Noel uses his first name, "Robert," notably surprises him, highlighting this dynamic.

Chase's role focuses on investigation and interrogation. Early assignments involve analyzing malfunctions in security artificial fairies. He collaborates with Free Underbar and fairy technicians Hanns Efmed and Ted Livingston, though initial inquiries find no clear cause for the technical failures. His methods surface during the interrogation of a Black Fairy Tome suspect; when the individual refuses to cooperate, he pragmatically determines that extreme physical coercion would prove ineffective.

Persistence defines his investigative approach. He consults contacts within the Security Bureau and fairy engineering teams, gradually uncovering links between the malfunctions and the organization Arcame. This leads him to identify Eddy—a figure he pursued during his Security Bureau tenure—as potentially involved. After reporting these findings to Dorothea director Nein Auler, he receives authorization to continue his investigation and coordinate with the Security Bureau.

His inquiry shifts significantly upon learning that senior artificial fairy technician Hanns Efmed has been detained by the Security Bureau. Visiting Hanns in custody, Robert pressures him to reveal withheld information. Later, discovering that Eddy’s son is technician Ted Livingston, Robert confronts Hanns again. Together, they deduce Ted’s manipulation of newer artificial fairy models and his use of a device to control older units. Recognizing the imminent threat, Robert urgently alerts Nein Auler and rushes to a public plaza to thwart Ted’s assassination attempt on Prime Minister Golbarn Helwise. His intervention proves critical in Ted’s arrest.

While specific developments in later seasons or spin-offs are not detailed, his investigative tenacity and analytical role within Dorothea remain consistent throughout his depicted activities. His story may extend beyond these recorded events.
