Hayate Gekko was a calm and balanced person, rarely losing his temper even in tense situations. He was described as an individualist with a gentle and kind nature. His sense of duty to Konoha was extremely strong, so he risked his life without hesitation while tracking Kabuto Yakushi and Baki. Despite a constant exhausting cough and clear signs of illness on his face, he never complained about his health and never allowed his ailment to affect his service. He treated others evenly and respectfully, for which he was valued by many shinobi, including Kakashi Hatake. He felt a deep attachment to Yugao Uzuki: alone with her he allowed himself a light teasing tone, but at the same time seriously worried about her safety after her transfer to ANBU. His colleagues respected him for his fairness and impartiality, which is why he was trusted to judge the preliminary matches of the Chunin Exam. He never raised his voice without need, preferring to act rather than speak. Even in the midst of battle, his face retained a focused calm, as if he was calculating every move in advance. The romantic side of his nature was only revealed around Yugao, when he swore by the moon to protect her and stay with her until the end. He was not afraid of death and accepted it with dignity, trying to fulfill his mission until the very last moment.
