真瀬 由子

Yuuko is a third-year at Himematsu High School and the sergeant of the team. She is mostly shown smiling, never once getting devasted nor changing emotions when something bad happens to her. While at first glance it appears as though Yuuko is a normal player with no outstanding abilities, unlike Himematsu's vanguard and lieutenant, Yuuko is seen to be a formidable player, having a positive score in both the quarterfinal and semi-final matches.
