Shun Izuki (伊月 俊 Izuki Shun) is a second year regular point guard and vice-captain at Seirin. He has the Eagle Eye.
Izuki has straight black hair, that reaches his eyes. His eyes are narrow and resemble an eagle, hinting to his ability. His eyes are also usually shown without pupils, entirely black. He has a rather small and athletic looking body, in contrast to his teammates. He plays with the jersey number 5.
His appearance hasn't changed much from last year, but in his first year in high school, his hair was shorter and parted on the right side.
On the outside, he has a cool attitude, but on the inside, he has an unfortunate hobby for puns (word-jokes). Apart from his puns, he is also very smart. He plays his matches with a cool-headed personality. He is an excellent strategist.
Izuki is shown to have played middle school basketball with Hyūga and is dissapointed that his friend has decided to quit basketball after a dissapointing middle school record because of the Generation of Miracles. Along with Kiyoshi's help, Izuki and the other Seirin members try to recruit him but most of their attempts fail. In the end Izuki is delighted to learn that Hyuga is joining their team.
He is shown showing concern when Hanamiya injures Kiyoshi during their match against Kirisaki Daiichi.
It is then shown what Izuki's talent is: the Eagle Eye. Kasamatsu commented that he is the key playmaker of Seirin High. After he makes the shot, he made a pun to Hyūga, prompting Hyūga to threaten Izuki by subbing him out.
The finals of the Interhigh preliminaries are about to begin and Hyūga fires the team up. The match commences and Kagami and Ōtsubo jump for the tipoff. The ball goes from Mitobe to Izuki and Izuki passes to Kuroko, who redirects the ball to Kagami for an alley-oop. Midorima blocks, Takao drives the ball upcourt and faces Izuki. Takao passes behind his back and foils Izuki's defense.
The match continues and Takao goes up against Izuki yet again. Takao uses his speed to cross Izuki, while Izuki can only amaze Takao's fast movements. Takao passes behind his back to Ōtsubo, who's open and Izuki wonders if he has a Eagle Eye too. When Takao blocks Kuroko's pass, Izuki confirms Takao's ability. He tells Hyūga that Takao has the Hawk Eye, an even stronger ability than Izuki's. He says that Kuroko's misdirection won't work against Takao.
He appears at the Winter Cup alongside Seirin at the opening ceremony and while entering the field. At the tip-off for their match against Tōō Academy, he receives the ball from Kiyoshi. Following Riko's orders to score quick and strong, Izuki dribbles up the ball fast, but runs into Tōō's pressure defense. Unexpectedly, Tōō doesn't underestimate Seirin and Izuki is covered tightly by Imayoshi. He tries to pass to Hyūga, but the ball is stolen by Sakurai. As Sakurai and Aomine perform an alley-oop and the first point is scored, Izuki passes the ball back into the game to Kuroko, who prepares for his Ignite pass Kai. Kagami scores and Izuki is seen guarding Imayoshi before he passes to Susa. After Kagami's simulation battle with Aomine, he passes to Izuki. The ball eventually goes out of bounds and Seirin calls for a time-out. During the meeting, Izuki says that they're stuck in a rough battlefield. Hyūga says that the solution is him scoring a few three-pointers and tells Izuki to pass to him. At the match Izuki passes and Hyūga does indeed score. Both Hyūga and Sakurai continue to shoot until the first quarters end.
At the beginning of the second quarter, Izuki passes the ball to Kuroko who attempts a Vanishing Drive on Aomine, but fails. Izuki passes the ball to Kuroko once again, but realizing that he was going for an Ignite Pass Kai, tries to warn Kuroko that neither Hyūga nor Kiyoshi have gotten awake from their marks. Trying to get the team to calm down, Izuki passes the ball to Hyūga but is intercepted by Wakamatsu who performs a lay-up. As Kuroko stays on the bench from being subbed out, Izuki and the rest of Seirin are surprised at Kagami's skill being able to keep up with Aomine.During the beginning of the third quarter, Izuki is surprised because his mark changed from Imayoshi to Susa. Imayoshi then blocks Izuki's pass to Kuroko and shoots a 3 pointer surprising Izuki. Izuki then passes the ball to Hyūga for him to attempt to make a shot. As the third quarter almost ends, Kuroko's Misdirection runs out, and Imayoshi goes back to guarding Izuki. The teams spirit does not falter and Izuki tells Imayoshi that they let Kuroko's Misdirection run out. Izuki dribbles the ball and disappears from Imayoshi's sight, appearing behind him and scoring a point. Seirin pulls out their final trump card, Misdirection Overflow. Even with the use of Misdirection Overflow, Imayoshi shoots a sudden three-pointer from across the court surprising Izuki, and ending the third quarter.
During the fourth quarter, Seirin's defensive strategy turns into a Zone Press. Aomine then enters the Zone making Izuki's passes intercepted by Aomine. Izuki tries to drive past Imayoshi with the Misdirection Overflow but it begins to start to run out. As Kagami enters the Zone, Izuki and the rest of Seirin leave the game to Kagami, in which they win the game.
Izuki is not very athletic but can shoot, pass and dribble on a high level. According to Hyūga, he started playing basketball in second grade, the earliest compared to anyone in Seirin. Izuki doesn't have any specific offensive skills, but he is fast and agile, able to change direction while dribbling and foiling his opponents easily, and also uses his speed in making easy lay-ups during fastbreaks. He has also been seen to successfully shoot a three-pointer. Despite being at a position where he can rarely shine, Izuki is nevertheless important for Seirin's attacks pattern and as such being nicknamed the "control tower" of the team. A chart of his skills were included with his profile in the CHARACTERS BIBLE. His stats are balanced but he excels in technique.
During Seirin's finals in the Winter Cup, Imayoshi observes that Izuki managed to improve himself in the middle of the match, mirroring the transformation of the Uncrowned Kings of Rakuzan. He succeeded in stopping Hayama's four-fingers dribbling, which even Kagami or Miyaji (against three fingers) couldn't have done. Though failing to stop the five-fingers all by himself, he successfully lured Hayama into Kagami's large sphere of defense with Kuroko's help because he knew that he won't be able to match his speed. His ability to think ahead was also a key factor that Seirin managed to cut the deficit to 1 against Rakuzan because of his correct prediction that led him to steal the ball.
As a point guard, Izuki possesses a very useful ability. Using his Eagle Eye, he can see the basketball court from a different perspective. As if he watches plays from above, he can see the formation of all the players and develop a strategy accordingly. Practically, he can use it to pass efficiently and move so that two of the opponents collide with each other.Hawk Eye, which Mayuzumi takes advantage of. His vision also served him to predict Hayama's Lightning Dribble
Eagle SpearEditThrough repeated practice, Izuki can steal the ball from behind his back, without looking, from a much faster opponent like Kasamatsu. He uses his Eagle Eye to see the position of the ball and locate the opponent. By not turning his body and simply lunging his arm to the desired direction, he can stop high speed drives, associated with his ability to think ahead before the opponent. He learned this from Kagetora during the Winter Training Camp.
