Oikawa has dark brown hair that is swept outwards and eyes of the corresponding color. Many others find him attractive, to the point where several girls follow him around. Oikawa frequently smiles and grins (although Iwaizumi notes that these expressions are rarely genuine). He tends to make victory signs or large waving gestures, which are often accompanied by broad smiles or a wink. Another trademark expression of his is sticking out his tongue while smiling and closing one eye.
Oikawa is of decent height for a volleyball player, standing just over six feet. While on the court, Oikawa wears a standard aqua and white Aoba Johsai High uniform emblazoned with the number one. He also wears dark gray athletic shoes with blue details. For unknown reasons, he wears a white kneepad on his right leg, contrasting with the black one worn on his left and by the other players in the series. At other times, Oikawa dresses in the Aoba Johsai uniform, which consists of khakis with dark brown detailing, a cream-colored vest, a dark red tie, a lavender button-down shirt, and a white blazer. During a practice match with Karasuno High, Oikawa dons a green #13 sports bib on top of an aqua t-shirt. It is also shown that he wears glasses in one instance, but it was revealed that those were fake glasses, which he bought "accidentally".
Despite his flirtatious nature (which makes him famous amongst female students, much to Tanaka and Nishinoya's envy) and childishness (as pointed out by his nephew and Iwaizumi), Oikawa is an excellent, well-rounded player and is extremely serious about volleyball. He's known to have a "disgusting personality" amongst both opponents and his own teammates because of his smug, and outwardly flippant attitude. Oikawa also frequently makes cheerful remarks but follows up with serious or intimidating afterthoughts. He is extremely intelligent and cunning and easily figures out both his teammates' and opponents' weaknesses.
However, on more than one occasion, Oikawa has been very attentive and caring towards others, but this is mostly seen with his teammates or people like Hinata (who he played beach volleyball with post-timeskip).
Oikawa is ambitious and one-track-minded, but it's shown that he also has feelings of inferiority towards those he deems as naturally better than him, Ushijima and Kageyama as examples. This is one of the main reasons he pushes himself so hard. Oikawa also holds a grudge against Kageyama, whom he mockingly calls Tobio-chan. This is due to his feelings of inferiority surfacing when compared to Kageyama, who has been hailed as a genius setter since their time spent at Kitagawa Daiichi. Kageyama and Ushijima can also unintentionally bring out the more childish or rash aspects of Oikawa's personality.
To match his ambition, Oikawa works extremely hard and often endures vigorous solo practices after his normal practices with the team. This has led him to injure himself in the past. In addition, Oikawa spends time at home watching past games of his rivals, observing their movements ahead of time, and strategizing how to defeat them. Despite that, he still takes time off on Mondays for rest.
It was seen post-timeskip that Oikawa has had thoughts of giving up on volleyball, but whenever that thought occurs, something really fun comes along to remind him why he loves it so much. Showing that while he has seemingly endless ambition, he does occasionally have doubts, though they never overwhelm him.
A former member and setter of Kitagawa Daiichi Junior High, he won the "Best Setter Award" in his prefecture during his 3rd year at the aforementioned school. As a former upperclassman and senior setter to Tobio Kageyama, he nearly hit him once after Kageyama requested that he teach him to serve, but was held back by Hajime Iwaizumi. He later felt guilty and showed remorse, and apologized to Kageyama. He'd been blessed with more athletic skill than most people and a good sense for things, too; Even so, there was an ever-present wall he couldn't overcome. The junior high section of Shiratorizawa Academy, which had become known as the strongest in the prefecture, and the "Herculean" Wakatoshi Ushijima, who numbered among its players.
In his final tournament of junior high, he and his team faced the Shiratorizawa team and won a set for the first time. They came in second to Shiratorizawa in the results, and it was there that Oikawa received the Best Setter Award.
Karasuno High Team Formation Arc
During the practice match between Aoba Johsai and Karasuno, Oikawa did not appear until the third set. He instantly gained the admiration of the female students that were present which caused Tanaka to instantly hate Oikawa. Before Oikawa joins the game, Kageyama admits that he learned how to serve and block just by watching Oikawa and it is because of this that he is dubbed The Great King by Hinata. When Karasuno is at match point, Oikawa is subbed into the game and instantly targets his serves to Tsukishima. From having watched during his warm-ups, he was able to tell that Hinata and Tsukishima were not strong when it comes to receiving and would therefore be the weaker players to target. This is the first time that Karasuno witnessed Oikawa's serves and saw that they were not only very powerful but Oikawa also had the ability to control where his serves could go. Oikawa is able to get two service aces in a row from targeting Tsukishima.
Aoba Johsai vs Oomisaki High School
In the match against Oomisaki High, Oikawa is seen getting numerous service aces. It's in the second set after he has scored his fourth service ace in a row that Ukai points out that it's Oikawa's control of his serve that makes it a force to be reckoned with. He then refers to setters as conductors because they are the ones who control plays and Sugawara adds that Karasuno actually does not know much about Oikawa as a setter. Kageyama also reveals that Oikawa and Iwaizumi have been playing together since grade school which explains how the two are able to work so well together. Ukai surmises that Oikawa is the type of setter who knows his team so well that he is able to bring out one hundred percent of their abilities.
Aoba Johsai vs Karasuno High School
Before the start of the match, Takinoue and Shimada notice how a lot of female fans are cheering for Oikawa, putting Seijoh's cheering section a step above Date Tech's in their opinion. They also notice how the Seijoh team has complete faith in Oikawa as a captain when they witness their change in behavior when Oikawa says he trusts them to play their best during the match.
Oikawa is quick to cause unease among the Karasuno team when he right away does a setter dump in the first play and then states that he will do the same thing in the next play. However, he changes to a set form when he looks to be carrying out his promise of another setter dump and sets to Iwaizumi. When Oikawa has his chance to serve, he sends his serve toward Nishinoya though the Karasuno libero is able to surprise everyone when he is able to receive. Ukai figures out that Oikawa purposely served to Nishinoya in hopes that the libero would not be able to receive and bring down the confidence of the Karasuno team.
During first set, Oikawa is able to decode the system that Hinata and Kageyama use to differentiate quick attacks and lay out a plan the counter it. Through this, he is able to build great pressure onto Karasuno by methodically shutting out attacks that will neutralize Asahi and Tanaka first and then nullify Hinata's decoy attempts.
Aoba Johsai vs Shiratorizawa Academy
Oikawa goes into the match hopeful that Aoba Johsai will finally defeat Ushijima and Shiratorizawa. But despite all the work and practice that Aoba Johsai had done, they are ultimately defeated. Unlike other schools, Oikawa and the other third years stay on the team after the Interhigh in hopes of getting revenge on Shiratorizawa during the Spring Interhigh .
Tokyo Expedition Arc
When leaving a Lil' Tykes Volleyball class with his nephew, Takeru, Oikawa runs into Kageyama. While the younger setter tried to obtain his help, Oikawa initially tried to ignore him until Kageyama put aside his pride and bowed to Oikawa. Oikawa took the chance to have his nephew take a picture of the encounter before agreeing to listen to Kageyama's situation of Hinata wanting to change the quick attack. Oikawa is supportive of Hinata wanting to change the attack and points out how the middle blocker is actually the one in control of the attack and not Kageyama. He continued to say that if Kageyama continued to be unwilling to change the attack, he would still be the same King of the Court he was during middle school.
Some time later, Oikawa welcomed Kentarō Kyōtani back onto the team after having personally asked him to return.
Spring High Preliminary Arc
Aoba Johsai vs Date Tech
In the game against Date Tech, Oikawa and Aoba Johsai are shown to have the advantage in the game but occasionally have trouble with Date Tech's new setter, Koganegawa. Oikawa seems the most concerned of Koganegawa's presence during the game as the first year setter add's height and strength to Date Tech's famous iron wall despite his inexperience. He had attempted to get through Date Tech's block by setting to Iwaizumi further from the net than he normally does and Iwaizumi was quick to tell Oikawa to keep playing the way he normally does and let the ace worry about getting through the blockers. Aoba Johsai wins the game in straight sets and advance to the next round where they would face Karasuno.
Aoba Johsai vs Karasuno
Just before the game is about to begin, Oikawa notices that Karasuno has a different atmosphere about them. He and Kageyama have a brief scuffle where the third year would proclaim that Ushijima was the only opponent worthy of facing him and that Kageyama and Karasuno would face another defeat against him. When Oikawa and Daichi shake hands, Oikawa points out that Daichi and the team seem more disciplined but is unsure of what Daichi means when he credits new friends the team had made.
During the team pep-talk, Oikawa would openly admit that Karasuno is a strong team and would attempt to tell his teammates that he trusts them only for his fellow third years to first announce their faith in him as their captain. Oikawa is momentarily left speechless by this and would try to repeat their words until Iwaizumi, Hanamaki, and Matsukawa warned him that he would owe them and the team ramen if he was unable to make his first serve count. Karasuno was able to cut off Oikawa's first serve.
Halfway into the set, Matsukawa had put together a plan that would limit where Hinata could aim his spikes. Thanks to this, Seijoh was able to counter and Oikawa praised Matsukawa for his clever plan. Near the end of the set with Karasuno one point ahead, Iwaizumi noticed Oikawa looked incredibly focused before his next serve. After covering his own head and warning Kindaichi to do the same in preparation, Oikawa unleashed his most powerful serve yet and left all of Karasuno speechless at the speed and power. However, the serve had landed out and thus put Karasuno at set point. It was at this point that Kentarō Kyōtani was subbed into the game by Coach Irihata. When Kyōtani unintentionally lost the set for Seijoh, Oikawa was completely stunned and left speechless. He was unable to figure out how to properly scold Kyōtani for his actions but Iwaizumi quickly took matters into his own hands. Before the second set began, Oikawa allowed Kyōtani to play how he wanted but warned the second year that he would not hesitate to have him taken out of the game if he caused any more problems for the team. While Kyōtani didn't seem to take Oikawa serious, he quickly obeyed Iwaizumi's warnings which annoyed Oikawa.
Oikawa's first serve of the second set also landed out but it was noticed by Daichi that his aim was getting better. After Kindaichi hesitated during a quick attack, Oikawa assured the first year that he didn't need to be afraid of Kyōtani and pointed out that Hinata had noticed his hesitation which told him that Kindaichi wouldn't be the one getting the set. Oikawa would soon use Kyōtani's presence to draw Hinata to one side which allowed him to set a broad attack to Kindaichi. Seeing that Kyōtani did not like being used a decoy but was still effective as one at the same time, Oikawa decided to use this to their advantage. Near the middle of the set, Hinata attempted a back attack but Oikawa was quick to block the attack and mock Hinata and Kageyama about having correctly guessing they thought the timing was right to use it. Just before Sugawara was subbed into the game, Oikawa was able to perfectly land a service ace with his improved serve that instilled a sense of fear into Karasuno. His next serve clipped the top of the net which allowed them to counter and stop his serve. When Sugawara was subbed in and began aiming his serves at Kyōtani, Oikawa noticed that Sugawara was doing this on purpose with the intention of causing Kyōtani to be late to attack. It would be during a time-out that Oikawa and the team came up with a plan to counter Sugawara's tactic and remove him from the game.
When Yamaguchi was subbed into the game, Oikawa noticed how different the pinch server seemed since he was last on the court. When Yamaguchi was able to land a service ace, Oikawa expressed that he dislikes jump float serves because of their unpredictable nature. Because of Yamaguchi's serves, Karasuno was eventually able to catch up to a tie and Oikawa would try to keep the team calm only to see that they already were and were in the process of preparing for the next serve. Oikawa is eventually up to serve again and gets a service ace when Nishinoya was unable to receive his serve. After a few plays, Oikawa joined in the celebration of Iwaizumi winning the second set. When Kyōtani was beginning to get out of control during the third set, Oikawa attempted to have Iwaizumi speak to the second year but Irihata had decided to remove him before this could happen. Once Yahaba was able to get Kyōtani to control himself, Oikawa was able to better use Kyōtani upon his return.
When Hinata and Kageyama accidentally discover a new attack of hitting a spike straight down, Oikawa comments how Kageyama's technique is not his strongest quality but rather his need to blaze forward when 'normal' people would be hesitant. He suspects that this trait was brought out by Hinata who Oikawa deems to be just as determined to push forward. Oikawa still sees that their new attack was born out of a fluke and is determined to stop them from further perfecting it. Oikawa is soon annoyed at Hinata when the middle blocker used a feint shot to get past Matsukawa. Near the end of the set, Oikawa is able to put Karasuno on edge when he lands a service ace that puts Aoba Johsai at match point. His next serve is received and countered. When Sugawara returns to the court, Oikawa picks up that he is now targeting Iwaizumi and refers to his serves as troublesome.
After Kageyama lands a setter dump and a time-out is called, Oikawa overhears Yahaba wish he had the same level of confidence that Kageyama possesses and recalls a moment when he spoke to an acquaintance of Coach Irihata's. He remembered the man telling him that if he continued to compare his own talent to that of someone else who was possibly born with great talent, he would never be happy because he would always be trying to overcome them.
When the game continues, Oikawa surprises everyone when he chases after a ball that is heading out and is able to make a perfect set to Iwaizumi on the opposite side of the court. Despite his best effort and being in place, Oikawa was not able to dig Hinata's block-out against Kindaichi's hand. Because of this, Karasuno won the match. Before he joined his team in leaving the court, Oikawa would tell Kageyama that they were tied at 1-1 and that he would beat him next time they faced each other. When Iwaizumi was being remorseful of not making his last spike count, Oikawa is the first to comfort him by hitting his back.
While the team is preparing to leave, Oikawa runs into Ushijima. Although he tried to ignore the ace, Ushijima spoke to Oikawa of how he allowed his pride to get the better of him which resulted in his loss. Oikawa would be surprised at Ushijima's blunt statement of how his team is the strongest because of him and would taunt the ace for being too prideful himself. Stating that he has never regretted choosing Aoba Johsai over Shiratorizawa and warns Ushijima that he himself could be caught off guard by a flock of crows.
Karasuno vs Shiratorizawa
Oikawa and Iwaizumi attend the match between Karasuno and Shiratorizawa though Iwaizumi states that Oikawa had claimed he would not attend the match because he would be angry no matter which team won. They appear after Tsukishima's return to the court during the final set (They appear in the fourth set in the anime). When the match is over and Karasuno has won, the two realize that Karasuno's victory is partly due to Tsukishima's plan of trying to get Ushijima into the habit of hitting straight shots out of muscle memory. Oikawa then ushers himself and Iwaizumi out of the gym before the award ceremony.
Tokyo Nationals Arc
Oikawa makes a brief appearance when he is seen watching Karasuno's game against Inarizaki. He is seen once more when he is watching Karasuno play against Kamomedai High when Hinata is being removed from the game due to his illness.
Beach Volleyball in Brazil
After high school, Oikawa became a professional volleyball player for the Club Atlético San Juan, a professional team in the Argentine Volleyball Federation where he plays as the setter. On a trip to Rio de Janeiro, Oikawa runs into Hinata one night at the beach when the younger player was playing beach volleyball.
After Hinata's game ends, the two head to dinner together where Hinata questions Oikawa why he went to Argentina. Oikawa reveals that he has loved volleyball since he was a child but became fully enamored with the sport when he and Iwaizumi attended a match between Argentina and Japan. The ace player of the Argentina team had been having trouble in the game until the coach switched the setters. The new setter, Jose Blanco, was able to bring the ace back on track through easy to hit sets and it was through his actions that Oikawa decided to become a setter. After having learned that Jose was acquainted with Coach Irihata, Oikawa would pretend he was unsure of whether or not he wanted to continue with volleyball just to be able to speak with him but Jose quickly figured out that Oikawa was just pretending but would still give advice on things that Oikawa was truly troubled with.
Hinata proposes they play a game of beach volleyball together. Oikawa confidently accepts but finds himself struggling with the sand and wind, much to Hinata's amusement. However, he quickly adapts for their following game a week later. He would even offer Hinata advice on how to observe their opponents and take them by surprise after predicting the next steps. Thanks to playing with Hinata, Oikawa rediscovers the joy of playing volleyball again.
Before leaving Brazil, Oikawa addresses Hinata by his first name and promises that he would defeat Hinata if they ever face-off in a match.
By 2021, Oikawa has naturalized as an Argentinean citizen. He would play on the Argentinean National Team, coached by Jose Blanco, at the Olympics where he would face many of his rivals on the Japan team. He and Hinata are seen sharing an embrace.
|High School Statistics|
He is most feared for his powerful and accurate jump serve, which he has honed and perfected from a young age. He can maintain a calm and cool composure during any match, no matter how tense it is. Despite not being considered a "genius", Oikawa is a stunning player and one of the best all-around players in the prefecture.
Unlike Kageyama's genius setting technique, Oikawa's talent lies in his natural athletic ability, his skill to make full use of his teammates, finding weaknesses in the opposing teams, sharp aims, and powerful serves. Within a short span of time on the court, he was able to point out that Tsukishima and Hinata were weak at receiving, and break Kageyama and Hinata's god-like quick. This, however, is not without years of dedication and practices. His talent is even acknowledged by Ushijima from Shiratorizawa Academy, who states that Oikawa's talent lies in his ability to draw the full potential out of any team.
Jumping Reach: 335 cm
|Post-Timeskip Skills Parameter|
- Jump-Serve: Oikawa is renowned for his powerful jump-serve, a technique he had seen on television and thought was amazing, so he worked hard since junior high to master the technique. He serves with pinpoint accuracy, often strategically targeting a member of the opposing team, a gap between two players (as seen with Nishinoya and Tanaka, as well as Daichi and Asahi) or using a different scheme to win a service ace. It is difficult to return, but Nishinoya's talent as a libero allowed him to do so skillfully. Because of the strain the jump-serve has on Oikawa's focus, his coach allows him to take time-outs and breaks alone to regain the concentration necessary to successfully execute them by focusing on the aspects that are easy to fumble.
During the Spring High Tournament, it seems Oikawa's jump serve has evolved. According to Sawamura, his serves can become so powerful that it can look like a spike. According to Coach Ukai, he seems to be putting more emphasis on power than control. Amusingly, the rest of the team requested the foods that they want Oikawa to buy if they lose the first point (where Oikawa lost the toss and was sent to serve.)
- Observant Perception: Both in-game and in daily life, Oikawa has a good sense of his surroundings and can effortlessly read others' moves and emotions. Because of this, he was able to pick up almost immediately on Kageyama and Hinata's strategy behind their god-like quick.
- Natural Talent as a Setter: Oikawa's tosses are made so that they are easiest for his teammates to hit. After each toss, he immediately asks how they can be improved afterward. Oikawa's abilities as a setter are so great that he is said to draw out the maximum potential of whatever team he is on. In particular, it is said that he draws out 100% of the potential of each individual spiker. He is also shown to be talented at performing dumps at the most unexpected times.
Aoba Johsai High
- Hajime Iwaizumi: Iwaizumi, often called "Iwa-chan" by Oikawa, is the latter's childhood best friend as well as the vice-captain of his current team. The two have been playing volleyball together since childhood and are extremely close. Iwaizumi is typically the one person who keeps Oikawa inline within Seijou, as well as disciplines him, usually with kicks or volleyballs thrown to the head (although it's notable that Iwaizumi threatens to hurt Oikawa more than he actually does). Despite being frequently annoyed by Oikawa's antics, Iwaizumi is shown to worry and care about him, often telling him to not overwork himself and cheering him up. Whenever Oikawa feels threatened by Kageyama's talent, Iwaizumi would berate him and remind him of his own strength. During the match against Karasuno, Iwaizumi reminded Oikawa to concentrate on the opponents at hand instead of the upcoming match against Shiratorizawa.
The two are nearly always in complete synchronization with each other on the court. It's well known that whenever Oikawa's in a pinch, he will toss to Iwaizumi. Oikawa and Iwaizumi have been through a lot together since junior high, Iwaizumi being the one that usually has to look after Oikawa. When Kageyama joined in the two's third years of junior high, Oikawa became jealous of his raw talent and started overworking himself in order to beat him. Oikawa's hatred of Kageyama got to the point where he nearly hit Kageyama, but Iwaizumi stepped in at the last minute. He yelled at Oikawa for his behavior and the two started arguing because Oikawa believed that he had to keep getting stronger in order to beat Shiratorizawa and Ushijima, his longtime rival. Iwaizumi then angrily headbutted and scolded him, stating that he was conceited and wouldn't be able to win against Shiratorizawa alone because volleyball is a team sport and "makes the strong even stronger". This finally got through to Oikawa and changed his way of thinking. It was after this notable change in attitude that Oikawa received his "best setter" reward, and both he and Iwaizumi angrily vowed to beat Shiratorizawa in the future.
After Seijou's loss to Karasuno during the Spring High Representative Playoffs, Oikawa comforted Iwaizumi by patting his back after the former began to question his abilities as an ace.
During the Seijou Extra, Iwaizumi nonchalantly stated that he believed Oikawa would probably not be happy because he's so hard to satisfy, but that Oikawa would keep moving on without hesitation. Iwaizumi said Oikawa is a partner he can boast about, as well as an amazing setter, but that if they fight Iwaizumi will defeat him.
- Takahiro Hanamaki: Hanamaki (Makki as Oikawa shortens to), like many of his team members, appears to have close relations with Oikawa.
- Tobio Kageyama: Kageyama was Oikawa's junior when they were in junior high but while Kageyama admired Oikawa, the latter hated him. Saying that he "hates geniuses", Oikawa disliked the raw talent Kageyama possessed and often refused to teach him anything when he asked, stating that it would be troublesome to deal with him in the future as rivals and adding an immature remark back at him. Despite this, Oikawa often comments that he's no match when it comes to Kageyama's accuracy in tossing, which annoys Iwaizumi.
During a practice match in junior high, Oikawa lost his patience and made multiple technical mistakes. He was then substituted by Kageyama, who impressively spiked and tossed. This frustrated Oikawa, which drove himself to work harder but all the while became more frustrated. While in this mood when practicing alone, the young Kageyama asked Oikawa to teach him how to jump-serve, to which he reacted violently and almost punched the boy in the face. He later apologized and was seen showing remorse and guilt over trying to hit him.
Kageyama, however, ended up learning his skills from Oikawa by simply watching him. Since junior high, he believed that if he surpassed Oikawa, he would be the best setter in the prefecture. He holds a grudging admiration towards Oikawa and respects his volleyball skills, but does not care so much for his personality. He is currently trying to master Oikawa's jump-serve.
During Karasuno's first official match with Aoba Johsai, both Oikawa and Kageyama get riled up by each others' taunts and jabs. Oikawa likes to purposely agitate Kageyama and throw his state of mind off-balance. Aoba Johsai ended up winning this match but Oikawa noted that Kageyama could beat him, just not now.
Sometime later, Kageyama approached Oikawa, asking for advice on how to respond to Hinata's desire to spike "of his own free will" instead of shutting his eyes and hitting with full power. Kageyama stated that Hinata doesn't have the skill and it's a ridiculous proposal. Oikawa originally refused to talk to him, but after Kageyama begrudgingly bowed to show his respect, Oikawa relented and replied that Kageyama should give it a shot. He explained that if Kageyama didn't, he would just be reverting back to his junior high days and that thinking his way is best is cowardly. Oikawa also told him that it's Hinata who takes the initiative in attacks, not Kageyama.
- Shōyō Hinata: From the moment they first met, Hinata proved to be someone Oikawa would need to be cautious of. Oikawa sees Hinata as a great decoy capable of being a great threat to opposing teams but still sees Hinata's inexperience as a player that he would at times use to his advantage. Years later, Oikawa would run into Hinata in Rio where their relationship would strengthen into a good friendship. Hinata would learn several tips from Oikawa as well as how Oikawa became interested in volleyball when he was young. When Oikawa left Brazil, he addressed Hinata by his first name and promised that he would defeat him if they ever faced each other in an official game. When they met again at the 2021 Olympics, they were seen embracing one another.
- Wakatoshi Ushijima: Ushijima has been Oikawa's rival since junior high, the latter never having won a match against him. Oikawa often refers to Ushijima as "Ushiwaka-chan", much to his disdain. Surprisingly, Ushijima recognizes Oikawa's talent, calling him an excellent player and stating that he should have attended Shiratorizawa because he draws out the maximum potential of whatever team he is on. Whenever the two bump into each other, Ushijima would remind Oikawa of this.
