Kimishita has a lean but athletic build of average height, with medium-length messy dark-brown hair and green eyes. He usually has an annoyed look on his face, often looking like he's about to pop a vein (or more, depending on his level of anger).
Kimishita wears his Seiseki uniform with a polka-dotted tie instead of the normal striped one. He also wears blue-framed glasses when studying. His casual clothes mostly consist of shirts with overly large patterns on them and clashing neon colours.
When playing, Kimishita wears Seiseki's black home kit or yellow away kit with black boots (in the manga, these are seen to be Nike boots, but the anime shows him wearing Asics boots).
Kimishita is not always an easy person to get along with, usually displaying some form of annoyance at his teammates and not hesitating to tell them exactly what he thinks they're doing wrong. He is harsh and rude and can be sarcastic at times, but he is also hardworking and intelligent and does not tolerate those who slack off and especially hates people who treat their equipment badly. As a player he is highly perfectionistic and even shows worry that he might be not good enough for national-level players like Mizuki, or being left behind by more skillful midfielders like Indou or Taira of Seikan. He has poor social skills but more common sense than most of his teammates, leading to him getting embarrassed a lot, either when he tries to express his emotions or whenever he experiences second-hand embarrassment at his team's antics. Despite his attitude he is also good-natured and will help anyone who needs it, even people he dislikes.
He is a second year student who plays as an attacking midfielder. Kimishita is the playmaker of Seiseki's team. He is also a set-piece specialist, and the team's designated free-kick and corner taker.
Sharp curved passes and accurate free kicks
As a left-footed player, He is better at inswinging corners than outswinging ones, but he has been known to use short balls with a shorter lineup. But when he went up against Seikan, his passes seemed really weak compared to Taira, despite both being left-footed players and similar in stature. He can also shoot and take free kicks with his right foot.
When shooting free kicks, he shoots right-footed, and can generate huge curves to shoot over an extra two-man wall set by him, where his teammates shields the ball so goalkeepers have even less time to react to the ball or who was the free kick taker. He also drew a lot of walls to jump, hence he developed a low-driving free kick in the Nationals Qualifiers semi finals match. He also completed the hat-trick with a near-impossible shot to the inside side netting from just outside the corner box near the right sidelines.
In the Nationals Qualifiers semi finals match, he had to take the team on his own given he has none of the Three Arrows available due to injuries or suspensions. He broke through the team's press man defence by using head fakes to sell the pass. But given he has been the main assist man in Seiseki, many teams overlooked his score-first mentality.
Kiichi Ooshiba : Kimishita and Ooshiba don't get along and are seen fighting whenever they interact, and it has been implied that they tend to avoid each other for that reason. However, they end up forming a reluctant friendship, with Kimishita taking pride in Ooshiba's growth as a player and as a person and giving him advice when the latter asks him (albeit reluctantly), as well as trusting him unconditionally on the pitch and helping him overcome his mark in the practice match against Seikan, and Ooshiba asking him for help and worrying about him when he almost gets hurt.
Hisahito Mizuki : Kimishita and Mizuki are partners, with Kimishita assisting Mizuki with his passes and Mizuki giving Kimishita sound word descriptions on what kinds of passes he wants, to the latter's continued annoyance. While Kimishita is usually irritated by Mizuki's antics and his own failed attempts to keep them in check, he also greatly respects and admires him, with flashbacks showing that Mizuki was the first player strong enough to handle Kimishita's passes. He wants to help Mizuki grow further and reach his full potential, but is also haunted by the fear that he may not be good enough or left behind by the other's rapid progress.
Tsukushi Tsukamoto : Kimishita doesn't start out overfond of Tsukushi, heavily questioning the coach's decision to make him part of the Inter-High lineup because it gives him one less option to pass to, considering Tsukushi's lack of skill. However, Tsukushi's hard work and progress as a player does eventually win him over, and he passes to him repeatedly in official matches, despite his original statement that he never would. It is also implied that Kimishita takes a liking to Tsukushi because the latter reminds him of himself in some ways, with both of them coming from rather poor single-parent backgrounds but being content about their situation, as well as both of them being hardworking individuals who think of the team first.
