Mai Nametsu (Japanese: 滑津 (なめつ) (まい) Nametsu Mai) is a second year student at Date Tech High and is manager of the boys' volleyball team.


Mai has big, round brown eyes with long eyelashes and thin eyebrows. She has light colored hair (brown in the anime) and usually wears it in a low ponytail over one shoulder. She is usually seen wearing a Date Tech High tracksuit during the team's matches.


Mai is generally very outgoing and cheerful. She is very supportive of her team and won't hesitate to praise them for a good play. She also has a good sense of humor. This is shown when she says "Nice catch" to Coach Oiwake when he caught a ball after his team messed up during a match.

Mai appears to have a more blunt side to her personality. She is seen slightly disapproving of the overzealous third-years when they constantly show up to spectate the team's matches. In addition, she, along with Oiwake, is seen wearing a smug face toward Coach Ukai after her team shows off their immense improvements in their serves[1].



Spring High Preliminary Arc

During the Spring Interhigh preliminaries, Mai watches the match between her team and Aoba Johsai together with Coach Oiwake. She is very supportive of her team and can be seen either doing a fist pump or out rightly praising the players when they make a good play[2].

Tokyo Nationals Arc

During the practice match against Karasuno, Mai observes her team and takes notes on their performance. She is delighted to find the team fired up and performing well in maintaining their blocks. Later when the retired third-years come to watch the match, Mai questions where they find all the free time due to them constantly showing up uninvited.

Throughout the match, she pays close attention to the strength and weaknesses of her team; like their improved blocking and the need to improve their receiving when Kinoshita scores a service ace with a jump float serve[3]. When Aone attempts his newly learned jump serve, she and Coach Oiwake wear a smug expression while silently gloating over their team's improved strength to Ukai when he comes to realize that Date Tech will most likely be the most challenging opponents the following year.
