Agano is a character defined by his dedication to his work and a deeply personal motivation that drives his research. He is a calm and professional individual, known for his expertise within ERDA. His most significant personal connection is to Ina Onari, the missing sister of the protagonist, Taisei Onari. Agano joined ERDA around the same time as Ina and knew her well, describing her as a genius who was admired by those around her. This connection is not merely a past association; it is the core of his character's purpose. Agano firmly believes that Ina is still alive, and he has made it his personal mission to carry on the research she started. He continues her work diligently, with the hope that she will one day return and be able to resume her projects where she left off. This devotion makes him a key figure in the story's emotional core, as his work is directly tied to the mystery surrounding the protagonist's sister.

In the narrative, Agano serves as an important source of information and historical context for the young pilots. He is introduced to Taisei Onari when the protagonist tours the ERDA facilities, and it is during this meeting that Taisei first learns details about his sister's past and her role in Shinkalion development. Agano is also knowledgeable about the technical aspects of the Shinkalion program. He has observed, for instance, that the Aptitude Value required to pilot the robots seems to be higher in teenagers, a piece of data that contributes to the understanding of how the machines and their pilots interact. His role is primarily supportive, providing the scientific and emotional link between ERDA's past and its future. Through his unwavering commitment to Ina's legacy, Agano Tsugawa represents the perseverance of research and the personal bonds that continue to influence the fight against the Unknown.
