Naoto Kōzuki

Naoto Kozuki (紅月ナオト, Kouzuki Naoto) is the older brother of Kallen Kōzuki and a member of the Resistance forces intent on liberating Japan from Britannia. He was killed before the start of the series, which spurred Kallen into taking up the fight against Britannia. Prior to his death, he was in charge of the Resistance cell being led by Kaname Ohgi at the start of the series, a position Ohgi took up due to his close friendship with Naoto. Within the series he is only seen in photographs together with Kallen, which Ohgi glances at while musing over his own perceived inability to be as good a leader as Naoto apparently was. He is also mentioned during the Black Rebellion, when Ohgi begged Kallen to follow Zero from the battle and guard him with her life, as he believed Zero was the one person capable of "realizing Naoto's dream".
