Mitsuteru Sakaki

is a second-year like Shinjou. He has long black hair that is usually kept in a ponytail. He is usually seen in his standard Ishiyama uniform and is the least talkative of the knights. He is the captain of the kendo team.
 * Sakaki is a very skilled swordsman and is able to cut a few hairs of Kunieda's with a wooden sword. However, he is not in her league: Kunieda is able to cut his sword with a ruler, to Sakaki's shock. He then begins to believe her the strongest of the Ishiyama students and longs to have a rematch with her. He even goes to the length of attacking her when she is unarmed and unwilling to fight back, but is stopped by Himekawa. The two men then fight and seem reasonably well matched, with Himekawa coming out in a slightly worse condition.
