Yestech, an Abh official of the empire's finance ministry, serves as an inspector evaluating planetary finances and resources, a role requiring travel to territories under imperial jurisdiction. He possesses light blue hair and green eyes. During the Hyde star system's reintegration, he is assigned to the light-armed transport ship *Bokbrusue* alongside Count Jinto Lynn, joining Jinto's retinue as the Count assumes administrative duties for his home system. His duties necessitate close coordination with Jinto, resulting in a functional rapport characterized by mutual respect, though Yestech maintains a demeanor consistent with his formal position. When Jinto departs the ship to negotiate with the resistant Martine government, Yestech is entrusted with temporary command of Jinto's vessel, indicating trust placed in him and competence in operational oversight beyond his financial expertise.
