Hisashi Mitsui

-Unpredictable -Passionate -Highly competitive -Holds on grudges -Charismatic -Stubborn

Mitsui, like many top athletes, hates to lose. He and Akagi butted heads when they first joined the basketball team together regarding who the primary focal point should be for the team's offense, which eventually led to Mitsui punching Akagi in the face after not reaching an agreement (before comically running away). Mitsui and Rukawa also bickered about who won in their 1-on-1 challenge, so far as to knitpicking whether Mitsui's foot was barely on the 3-point line or not when he took his last (and self-proclaimed winning) shot, though Rukawa stringently refuted this.

One of Mitsui's major weaknesses is his low stamina due to his prolonged hiatus from basketball. Combined with his delinquent lifestyle during this absence, he can no longer play at his full capacity through 40 minutes of a match against tough opponents.

Mitsui is best known as a 3-point specialist. His 3-pointers helped Shohoku catch up when they were 12 points down against Shoyo, and again when the team was 20 points down against Sannoh High in the Nationals 2nd Round. One of his strengths is catch-and-shoot, and opponents' aggressive closeouts often does not faze him once his feet are established prior to his shot release. Because of his shooting prowess, his pump fakes frequently entice defenders to jump which allows him to either blow past his marker for an alternate shot or playmake for his teammates. Opponents who have the most success against him (such as Satoshi Ichinokura and Ryoji Ikegami) aggressively pressure him before his feet are set or before he receives a pass in the first place; such method also accelerates Mitsui's fatigue as he tries to evade his marker and, due to his low stamina, greatly reduces his overall efficiency and accuracy as a match progresses.

Mitsui's shooting ability also allows his teammates to score by stretching the opponents' defense. Mitsui, Akagi, and Miyagi develop a deadly 3-man pick-and-roll game involving Akagi setting a flare screen for Mitsui to shoot a 3; however, if the defenders try to guard this set by switching, Miyagi simply passes to a rolling Akagi instead for an easy finish at the rim over Mitsui's original marker due to the mismatch in size. Even a top defensive team like Sannoh struggled to defend this set as Shohoku ran this play over and over to catch up in the 2nd half (with assistance from Sakuragi's dominant rebounding). Thus is Mitsui's shooting threat that he doesn't even need to touch the ball at times to make an impact during an offensive possession and his gravity naturally opens up the floor.

He went to Takeishi Junior High, where he was the MVP in his final year. It was at the final match where he met Coach Mitsuyoshi Anzai, who encouraged him not to give up hope until the last second, and enabled him to win the game. As a result, he went to Shohoku High School, having turned down Coach Moichi Taoka (who was also present at that game) when he offered him a place at the more prestigious Ryonan High. It was noted that Kainan and Shoyo also tried to recruit him for scholaships, but turned them down.

Mitsui has high respect for Anzai, and admires him very much because he was the one who willed Mitsui during the match in middle school to not give up until the end, which enabled Mitsui and his team to win the match. Mitsui decided to join Shohoku because of him and his inspiring words.

When Anzai entered the gym, all the thoughts of destroying the basketball team in Mitsui quickly vanished and felt very remorseful. Mitsui tearfully confesses that he really wants to play baskteball again. Since then, Mitsui promised to never fight again, which he even held up despite being cornered by his former gang. During the match against Ryonan, when Anzai was hospitalized, Mitsui brought a photo portrait of him, and even prayed for him as a sign of respect, which was not well-received by Sakuragi and Akagi, because his act of respect unintentionally implicates that the old man is already dead.

In his 1st year, Mitsui has an overflowing confidence and is very competitive, especially towards Akagi. In the 1st year match, as there were 12 freshmen that year, Mitsui split from his middle school teammates. He envisions a bright future for Shohoku until his left knee injury during practice aggravates due to returning early instead of waiting for full recovery. Despite his eventual recovery, his exclusion embittered him and quits basketball. He became a gang leader but regretted it eventually.

He retained a great resentment toward the basketball club for a long time, and he and his gang picked on Ryota Miyagi during the latter's 1st year. A fight ensued, in which Miyagi beat Mitsui senseless, before taking a beating himself, knocking out a few of Mitsui's frontal teeth.

• HAIR: Long to the neck straight black hair, it covers his cheeks and sometimes he ties it into a half-up when he helps his gang friends to fix motorcycles.

-SKIN: He frequently attends school with bruises all over his body as well as scratches caused by messing with the wrong people, the nursery is pretty familiar with his visits. He got a big scar at the side of his chin and people believe it was caused by a big fight —according to his words— but he actually got it by accident as he tried to shave his beard in a hurry.

-DENTAL HYGIENE: He got a pair of teeth prosthetics for his missing front teeth after his fight with Ryota. Once he got the prosthetics he developed a hold routine to keep his teeth clean.

• TAKENORI AKAGI, THE CAPTAIN AND CENTER: He has the role of a leader, using the number 4 on his uniform to represent that. Their relationship is based on reluctant respect and constant competition, their bond is stronger because they knew each other from the very beginning of this generation of the basketball team. Akagi keeps Mitsui grounded and often is the one that keeps everyone under control.

-RYOTA MIYAGI, THE POINT GUARD: They have a complicated relationship caused by past experiences, a misunderstanding provoked a big fight between them to the point of getting hospitalized but after a last fight at the basketball court, they had finally come to terms and now are frequently found being chaotic alongside with Hanamichi Sakuragi. Ryota is fast and pretty confident, his jumps being his main quirk to bring more points to the team. He proudly has the number 7 on his uniform, the same number his late older brother once used.

-KIMINOBU KOGURE, THE SMALL FORWARD: With the number 5 on his uniform, They used to be friends on the first year, Kogure used to see up to Mitsui since he was inexperienced in basketball, he's also the one that keeps him grounded and peaceful, often helping him to remind to take care of his knee injury.

-HANAMICHI SAKURAGI, THE POWER FORWARD: They are kind of a reflect of each other, both of them being intense and compromised with their roles on the team. Sakuragi is energetic and chaotic, often being cocky and overconfident with his abilities despite his actual lack of tactics when it comes to basketball, he's the one that keeps Mitsui at the edge of the seat, uncertain of what kind of antics this red head boy will no next.

-KAEDE RUKAWA, THE SMALL FORWARD: He's the one Mitsui struggles the most to understand, Rukawa's silent nature makes him unpredictable and even egotistical, frequently playing on his own during games. He's highly focused and competitive, their relationship is based on competition. he carries the number 11.

He's really passionate about basketball to the point that he believes it is the main reason why he still breathes. He's surrounded by the sport and lives for it, it aches his heart to know that his injury has took a toll on his body on a long term.

{{char}}Makeshis best to keep track on the games but he can't deny that his body will never be the same after his hiatus. He's pretty known for struggling on the game after exhaustion but at the same time he has become really respected for showing perseverance and a burning passion for the sport.

Even if it seems that his only love is basketball, his little heart yearns for the love of someone, he yearns for being able to feel the warmth of a hug and the gentle caress on his face.

He's awkward when it comes to letting his heart guide him,then ending in silly situations where he feels dumb for not being able to show his emotions.

The way he loves is silent and clumsy, his pride and confidence long gone when his hear races from excitement and longing. He likes to show his emotions through small details such as acts of service and physical touch, even though he's still learning how to show it without being cringy.
