Inarizaki High School, 3rd Year, Class 7 Height: 175.2 cm, Weight: 67.5 kg, Birthday: July 5th Family: Older sister and younger brother Position: WS (Captain, Jersey #1), Favorite food: Tofu hamburger steak Worries: His grandmother is already looking forward to his wedding. He dislikes static electricity, so he drapes his jersey over his shoulders because putting his arms through the sleeves sometimes causes a shock. He is a grandmother's boy; during the match against Karasuno at the Spring High Nationals, his grandmother traveled all the way from Hyogo to cheer for him. (Incidentally, his grandmother's sweater had "Go Shinsuke" written on it; she lamented that she had to use kanji due to character limits, but he told her it looked "cool.") His abilities are defense-oriented, and in terms of raw talent, he's just a slightly above-average player. However, he perfectly executes everything he can do in practice. He possesses that kind of confidence. He has said, "I don't see the point in getting nervous," and he doesn't make mental errors in play. He is stoic toward both himself and his teammates. When his teammate Atsumu Miya caught a cold and said, "If I don't play volleyball, it'll get worse," and other teammates admired his dedication, Kita flatly told him, "Go home. Don't praise him for failing to manage his health." However, in front of a grumbling Atsumu back in the locker room, there was a bag of supplies like hot lemon drinks left by Kita. A note was left: "To Atsumu: Eat properly and sleep. - Kita." This deeply touched Atsumu's heart. He only started playing in matches after entering his third year at Inarizaki High. During his three years in middle school, he never even got a uniform, let alone a starting spot. However, with strong mental fortitude, he faithfully follows his grandmother's teachings to do everything—academics, cleaning, club activities—"properly." He uses logic to shut down those who make negative comments, show poor play, or get unnecessarily heated. He puts pressure on Rintaro Suna with just his gaze when Suna starts slacking off during a match. Suna, a second-year, said, "His pressure is too intense even though he doesn't yell or hit." He always thought results were just a byproduct, but when he received the number 1 jersey for the new team, he was overcome with emotion and cried. His teammates thought, "I thought Kita-san was more like a machine." There were days when the Miya twins desperately searched for his weaknesses. He truly acknowledges the twins' talent and believes his job is to protect the backs of his teammates, including the mentally immature twins, and keep them stable. His motto is "Repetition, Continuity, Care." As depicted in the anime.
