Kasamatsu has short, spiky black hair and sharp steel blue eyes. In comparison to the other characters, he has rather thick eyebrows. He is of average height and build. While playing, he wears the Kaijō uniform with the number 4, as he is the captain. He also wears knee-high socks, and since this is something that no one else does, it makes him unique and easy to spot on court. The socks support his legs and lessen the burden on his muscles.
Kasamatsu is a very responsible and motivated captain. He can successfully lift his teammates' spirits when times on the court gets tough due to how determined, ambitious and strongwilled he is. He uses this motivation to strive towards the goal of winning the Interhigh for his team, because he is the cause of their loss last time. He is also shown to be courageous, as he stopped Aomine by jumping in front of him. He tries his best not to lose his cool during game situations in order not to demotivate his team, and he has successfully led Kaijō to many victories.
He is also good friends with Kise. At first, he strongly disliked Kise due to his big ego, as well as his tendency to get sidetracked by girls who were watching him play, which could get in the way of a game, much to the captain's frustration. However, he slowly warms up to Kise, and they become closer friends as Kise matures, thinking less of his own skills and starting to rely on his upperclassmen more. Kasamatsu trusts Kise as the ace player, but still has no problem with setting him straight when his ego is going over the top.
Last year, he and Kaijō High were defeated in the Interhigh preliminaries. This was because when Kaijō was one point ahead, Kasamatsu made a miss pass and let the opponents take the win. He wanted to stop basketball at that time, but Kaijō's coach, Takeuchi, made him captain. He decided that they would win the Interhigh next year, proving his resolve and position as captain.
IntroductionEditAs Kaijō's captain, he receives admissions from freshmen members at the first practice session. The last one of the first years is Ryōta Kise, who cheerfully introduces himself. Kasamatsu is irritated by Kise's self-conceitedness and kicks him. Kise is shocked to see the treatment he, a member of the Generation of Miracles, receives, but Kasamatsu opposes by telling him he is still just a freshman. Kise stands up to Kasamatsu, saying that he doesn't care about that hierarchy and that he's better than him anyways. Kasamatsu tells him that before even thinking something like that, he should consider the amount of work the second and third years have put into the team. After this, Kise seems to grow respect towards the senior.
Seirin vs KaijōEditKasamatsu appears for the first time on Seirin High's practice match against Kaijō. When the players enter the field, they don't notice Kuroko and Kasamatsu is surprised when he sees him, thinking that he won't such a big deal. The match starts and Kasamatsu dribbles up the ball, saying that they'll start with scoring once. Suddenly, Kuroko steals the ball away from Kasamatsu, passes to Kagami and Kagami dunks, breaking the rim.
Kaijō's coach is convinced to use the whole court and the match restarts. When a pack of wild schoolgirls use scream attack, Kise waves at them. Kasamatsu tells Hyūga that it's always like that, but kicks Kise on the back and scolds him. He tells him they should return the favor to Seirin. He passes to Kise, who copies Kagami's move and dunks. The match goes on with a too high pace and Seirin requests a time-out. On the bench, Kasamatsu asks Kise about Kuroko. Kise tells him Kuroko's weakness.The match starts again and while Seirin is guarding Kise, Kasamatsu replies with a sudden three-pointer. The match goes on with Kise overpowering Kagami and eventually, Kagami and Kuroko start their co-operation play. Kasamatsu analyzes their play and judges that Hyūga's pretty good too, after he scored some three-pointers as well. He further comments on the progress on the match and tells Kise at the end of the match to prepare for the revenge. When Seirin leaves, he shakes Hyūga's hand and tells him they'll meet again at the Interhigh.
Semi-finalsEditAt the Tokyo preliminaries, Kasamatsu is seen with Kise, walking towards the Interhigh building to see Seirin's semi-finals against Seihō. As they are walking towards the gym, Kise is looking at the morning show and tells Kasamatsu that Midorima has the best luck, in contrary to Kuroko. When they arrive at the match, they see that Seihō is dominating with 12 – 0. Kasamatsu says that Seirin is a team that starts slow, but that the usual accelerator (Kagami) is missing. He later explains Seihō's training secret, the martial arts with the Nanba run. Kise is impressed with his knowledge and Kasamatsu clarifies that he got it from a magazine.
When Seirin finally starts scoring, but Seihō still leads, Kasamatsu discusses it with Kise. He says that Seihō isn't just one of the Three Kings of Tokyo because of their defense, their offense is top-notch too. He compares them with other special teams by saying that Seihō aren't geniuses, but that they're experts. Kise says that Seirin has an expert too, namely Kuroko.
Later on in the match, Kasamatsu notices Kagami's overheating and exhaustion already in the second quarter, plus Kagami's foul trouble. When he and Kuroko are pulled out, Seirin shows their true style and Kasamatsu sees that their gameplay is back to the drilled original. He also sees Izuki's Eagle Eye.
Kaijō High faces Fukuda Sōgō Academy in the Winter Cup quarter-finals. Because Kise had to face his former teammate, Haizaki, he asked Kasamatsu to go outside during warm-up for a bit. The captain gives his permission. When both teams line up, Kasamatsu recognizes Hideki Ishida as a national-known player. He wonders why such diligent person would use Haizaki. The match begins and Kasamatsu gets the ball. He sees that Kise is guarded by a tight defending Haizaki and decides to drive inside and pass it to Moriyama, who's free for the three-pointer. Moriyama makes the shot.
The first scheduled semi-finals of the Winter Cup is Shūtoku High vs Rakuzan High, so Kasamatsu and his team are waiting in the locker room. When the match reaches half-time, Kaijō and Seirin hit the court to warm up. The team is later seen watching the second half.
As the match is concluded in Rakuzan's advantage, Kasamatsu is seen warming up for their game next. The match is about to begin and Kasamatsu says to Kise to give them a greeting, at which Kise copies Kagami's lane up and finishes. Kagami returns the favor and both team line up on the court. Kasamatsu and Hyūga exchange a handshake and Kasamatsu notices that he matured into a fine captain, which pleases Kasamatsu. The match finally begins and Kuroko engages a fast assault and scores with his Phantom Shot. It is returned by Kise, who has already entered Perfect Copy. During the next attack, Kasamatsu retrieves a loose ball and passes it directly to Kise, opting for a lightning fast transition. As Kise faces Kagami on the other side of the court, Kasamatsu comments on Kise's use of Akashi's Emperor Eye.
Kaijō has the initiative and Seirin is having trouble scoring. During Kaijō's offense, Kasamatsu fakes a pass to Kise and sends it inside for Hayakawa. His shot is blocked however. Kasamatsu is impressed by Kiyoshi. To slow down the pace, Riko sends Furihata in. Kasamatsu sneers and calls Furihata a terrified brat. Furihata dribbles up court but fumbles the ball and Kasamatsu steals it. Kuroko however, steals it back and asks to go easy on Furihata, as he is a little nervous. Kasamatsu is irked.
He continues to guard Furihata during Seirin's next offense and when seeing Furihata's cautious playing style, Kasamatsu understands Riko's goal by putting Furihata on. Hyūga scores a three pointer and Kasamatsu dribbles the ball up court. He is met by a passionate defending Furihata. He's however no match for Kasamatsu's speed and agility, who passes him with a nifty move. Kuroko suddenly reaches in for a steal, but Kasamatsu spins around and avoids him. He pulls up for a jumper but misses the shot, it is rebounded by Kiyoshi. Kasamatsu later thinks by himself that Furihata is especially good at supporting others and that he avoids danger well.
Kasamatsu is one of the best players in the league, but can be beaten by exceptionally good players like the Generation of Miracles and Uncrowned Kings. He has a ridiculous speed and supreme ball-handling, coming together in an almost unbeatable drive. His other specialty, are his outside shots. That is a lethal combination, as either the opponents closes in and Kasamatsu uses his drive, or the opponent keeps his distance and Kasamatsu shoots. This is a very orthodox way of playing, relying on capable technique, the kind that Kasamatsu possesses. However, this combination was successfully countered by Izuki's Eagle's Spear. He is also capable of setting up nice passes for his teammates to score.
Apart from his two main attack patterns, Kasamatsu has been noted for his leadership skills, being able to fire his team up in a critical time. He also utilizes his speed for fast and accurate steals. His endurance and passion in the game is fitting for a national-reputed guard.
