First Lieutenant Harold Katori, 20, serves as pilot and navigator aboard the United Planets Space Force destroyer *Soyokaze*. He presents blonde hair, though this is actually a wig carefully maintained to conceal baldness and ensure proper positioning. Katori maintains a consistently calm, peaceful, and well-mannered demeanor. This tranquility manifests in his frequent use of Buddhist sayings woven into conversation and his practice of meditation during spare time. His spiritually grounded personality fosters positive relationships with the crew, notably earning him exclusion from criticism during the women's discussions about male crew behavior. Katori demonstrates well-founded confidence in his piloting and navigational skills, executing precise maneuvers with large vehicles even under duress, such as evading enemy fire during sharp turns. He developed trust in Captain Tylor earlier than most of the crew and subsequently follows Tylor's orders without question. During work breaks, Katori enjoys drinking green tea.
