He is angered easily by Haru's apparent disobedience and impassivity. He is kind and firm, aspects shown often around his team.

History
Kirishima Natsuya was the captain of Iwatobi Swimming Club in Iwatobi Junior High. His little brother, Kirishima Ikuya, also participated in his team. One of his closest friends was Nao, the team manager. He ended up recruiting Haru, Makoto, Asahi and his younger brother for the team shortly after they began their first year of middle school. The movie and light novel ends with him still holding his title as the captain of the team.

He appears to have a good relationship with Nao. The tension between him and Ikuya eases up toward the end of the light novel. He seems easily agitated by insolence, as shown by the younger members of the team when they were not cooperating with each other.
