Kanoka is a fairly tall, athletically built young woman with dark hair kept in a short bob. She has large eyes with long lashes and is noted by Tanaka to have grown attractive. In her childhood, she was taller than most of her peers and wore her hair longer.
Kanoka appears to have a friendly and polite disposition. She talks to Tanaka candidly, respects her upperclassmen, and shows concern towards Nishinoya after catching him from falling. She is much shyer around her crush, often blushing and stuttering.
Kanoka and Tanaka used to be neighbors and attend the same elementary school until she moved away in fourth grade. She towered over peers and was picked on by her school mates for her physique. Tanaka would chase away the bullies and encouraged her to keep her chin up. At some point, he took her to his junior sports team and introduced her to volleyball, which she has been playing since.
Spring High Preliminary ArcEdit
In the manga, Kanoka first appears during the Spring Interhigh Qualifiers (this scene was cut out from the anime). Her team walks onto the gym and Tanaka tries to call to her from the balcony. Her teammates quickly glare at Tanaka, causing him to back away fearfully as Hinata and Kageyama watch on.
Tokyo Nationals ArcEdit
On the first day of nationals, Kanoka and her teammates are waiting in the stadium with other schools for the opening ceremony. Hinata accidentally bumps into Nishinoya, causing him to lose balance and fall toward her. Kanoka catches him to stop his fall before asking if he's okay. While Nishinoya responds, Tanaka notices her and approaches her excitedly. They catch up for a bit until she's called away by a teammate.
Later in the day, Niiyama Girls returns to their hotel after practice. Kanoka sneaks away to greet Tanaka and congratulates him on Karasuno's win. She blushes heavily as she tells him to do his best and hurries away. She catches up with her teammate, who teases her about Tanaka. Kanoka reveals that Tanaka was the one who protected her from bullies making fun of her height during elementary school and introduced her to volleyball. She credits him for helping her become more confident. Her teammate teasingly asks if that's all there is to it, and Kanoka becomes too flustered to explain her feelings.
That night, Kanoka's sitting outside when she sees Tanaka pacing around. They talk for a little while before Tanaka suddenly announces that he already has a girl in his heart when Kanoka's cousin appears at the same time. Assuming that the guy is Kanoka's boyfriend, Tanaka runs away and leaves Kanoka heartbroken. However, Kanoka quickly asserts that she didn't come to nationals to date guys and will win all of her matches. The next day, Tanaka apologizes for his odd behavior and learns that the man he had assumed was her boyfriend was actually her cousin. Kanoka then thanks Tanaka for how he had helped break her slouching habit in childhood and requests that he pays close attention to how good she has gotten in volleyball before running off to join her team.
In the Final Arc, Kanoka continued playing volleyball and is now part of the V-League Division 1 team the Hikari Pharmaceutical Red Rabbits. She also plays on the Japan Women's National team at the Olympics.
As a member of Miyagi Prefecture's champion girls' team, her skill levels must be very high. In addition, Tanaka has referred to her as Niiyama's up-and-coming ace. When part of the National team, Kanoka is called the ace by the announcers.
They have known each other since grade four of primary school, having been neighbors before Tanaka moved away. Tanaka often chased away her bullies and encouraged her to keep her chin up and later introduced her to volleyball when he took her to his junior sports team; Kanoka credits him for helping her gain confidence. They were close friends and she still calls him "Ryū-chan", and he calls her by her first name. She was happy to see him again at nationals, and he's flustered by how beautiful she's become. Kanoka is shown to have a crush on Tanaka, getting flustered when she talks to him and when she talks about him to others; she became heartbroken when he announced that he already likes someone else, but resolved to keep her focus on volleyball instead.
Also at times when she would feel insecure or feel like giving up in volleyball, Tanaka always told her to "keep trying!" and she admired him greatly for this attitude and eventually the admiration seemed to turn to a genuine crush on him.
