Character Profile: Hajime Mizuki

Hajime Mizuki is a brilliant tennis player who can map out a winning tennis match in his head that could guarantee high success rate if followed after studying enemy players, as well as knowing his team's capabilities. He also recruits talented tennis players for St. Rudolph considering how weak the team was and the only decent player was Yuuta Fuji and Kisarazu Atsushi.

He recruited Yuuta by the time he transferred out and uses this to his advantage, further fueling the bitterness Yuuta felt toward his older brother. In turn, Mizuki taught him the Twist Spin Shot which could end his tennis career if used with an immature arm muscles and joints and Yuuta was indeed immature in his playing arm, but could execute the skill with proficiency. Ryoma pointed out the drawback in his technique and Fuji and Ryuzaki hearing it was shocked, and Syusuke Fuji was downright furious. Fuji got his revenge by letting Mizuki think he wasn't any good and let Mizuki win a couple games, and then became an awakened lion and beat him in minutes flat in full level, humiliating him thoroughly. Since then, Mizuki disliked Fuji though he began training Yuuta seriously, ala Inui style and proclaimed him 'his disciple'.
