Mitsuteru Sakaki

is a second-year like Shinjou. He has long dark green 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.

Appearance
Sakaki has long black hair (green in the anime), tied in a ponytail, with long bangs. His eyes are constantly squinting, unless he's very serious, shocked, or surprised about something.

Personality
Sakaki is a man of few words, and is a no-nonsense guy when he fights: his blows are to the point, and he doesn't engage in banter. He seems to be friends with Shinjo.

While examining Kunieda he whispered "Moe..." and "Tsundere girl" implying he might be an otaku. He also might have a crush on Kunieda.

Abilities
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.
