Akuto Mitsuya

No. 17 on the first string before Renji took the position. Akuto is a data tennis player like Inui and Renji, and actually taught Renji data tennis himself during a chance encounter when the latter was just returning home one day. Unlike Inui and Renji, Akuto's eyes can actually be seen a majority of the time. He provides intel support to the Japan team during the U-17 world cup, and even creates disgusting rice balls, known as Akuto Meshi, akin to Inui's special juices, for the team as motivation to not fail. Eating one not only knocks a person out (including Fuji), but also potentially dislocates all of their joints.
