If I couldn't bump that ball... the rally would end right there. All of a sudden... I realized that I was scared. Knowing that, there was only one thing to do. Face it.

Sō Inuoka (Japanese: 犬岡 (いぬおか) (そう) Inuoka Sō) is a first-year student from Nekoma High. He was initially one of the team's middle blockers but was later switched to a wing spiker.

As of 2021, he works as a childcare professional[1]


Inuoka has a lean build and is amongst the tallest players on Nekoma's team. Hinata dubs him Lanky in their first match together before knowing his name. He has short, spiked upwards brown hair and identical brown eyes. In the manga, his appearance the same, with exceptions for his hair being blonde and his eyes being amber.

Post-timeskip, Inuoka mostly appears the same but his hair is noticeably shorter.


Inuoka has a very bright, bouncy personality that is similar to Hinata's. It has been mentioned by Coach Naoi and Kenma that he isn't very smart. Although he is very serious when playing volleyball, he is also really passionate about his position as a middle blocker. He is also shown to be very caring and encouraging towards his teammates. Additionally, he is a very hardworking person, demonstrating this when he worked on his receives solely to manage to get a spot as a regular.


Not much is known about Inuoka's background, but it is known he played as a middle blocker during his time in middle school.


Karasuno High Team Formation Arc

Inuoka first appears during a practice match Nekoma has before their match against Karasuno. After the first practice match, Yamamoto tries to make a bet with Inuoka and Shibayama about whether or not Karasuno has a female manager. Afterwards, he shares in his teams surprise at hearing Kenma admit that he was looking forward to their match against Karasuno the next day.

When seeing Hinata and Kenma talking, Inuoka and Shibayama both get surprised at the two appearing to know each other. Shortly after, Shibayama and Inuoka rejoice at winning the bet and getting a Häagen-Dazs when Kiyoko appears and confirms that Karasuno has a female manager[2]. When meeting Hinata for the first time, Inuoka marvels at his short height. When the shorter blocker tells him to cease underestimating him, Inuoka assures him that he wasn't underestimating him at all. At this, Kageyama gets frustrated over Inuoka’s naivety.

When first seeing Hinata and Kageyama’s quick set for the first time, Inuoka becomes shocked and doesn’t know what to do. During the next rally, Inuoka is wary of Hinata’s speed, which makes him fall for his decoy trick. For Nekoma’s first time-out, Kenma has Inuoka commit to Hinata as he is the most agile on the team and therefore the best suited to keep up with Hinata.

As the match progresses, Inuoka manages to get his hand on Hinata’s quick several times but still isn’t able to fully block him. Despite this, it makes Karasuno cautious of the blocker as they notice he is starting to catch up to Hinata. After this, Nekomata comments on how Inuoka’s weakness is his lack of thought during a game but when giving him a clear task, that’s when he would shine. In the following events, Inuoka unintentionally tricks Hinata into making him think that he would do a quick set with Kenma but the setter instead goes a for dump.

Inuoka would later win Nekoma the first set when being able to block Hinata and Kageyama’s quick set for the first time, making him the first person being able to do that. In the first few rallies of the second set, Inuoka continues to effectively block Hinata. After blocking Hinata multiple times throughout the match, Nekoma thinks it would be about time to sub Hinata out for a more experienced blocker. Despite this, Hinata proves that he still wants to play and tells his setter that seeing Inuoka struggling to keep up with him every rally makes him want to continue pushing forward.

Once Hinata finally successfully hits Kageyama’s sets with his eyes opened, Inuoka, who now calls Hinata by his first name, is still amazed at his new friend’s reflexes and praises him for his impressive spike. Shortly after, Kenma uses Kai as a decoy for Inuoka to spike, but he is deflected nevertheless. Right after, Hinata goes for a quick with Kageyama, but Inuoka is able to catch up with his speed. As Hinata scores past the other rookie blocker, Nekomata finds Hinata and Inuoka to have both found worthy rivals. When being blocked by Tsukishima, Inuoka finds himself impressed.


Following the practice matches ending, Inuoka is still full of energy when reaching out to Hinata. When conversing, the two end up talking in gibberish out of excitement. Despite having being opponents earlier, Inuoka isn’t afraid to admit being impressed by Hinata’s fast reflexes and speed and receives similar praise from Hinata as well.

Tokyo Expedition Arc

During the summer training camps, Inuoka is revealed to have been replaced as a starting regular by his teammate, Lev Haiba[3]. Because of this, he is now mostly seen supporting the team from the sidelines with the rest of the Nekoma team but has made it clear that he will not be so easily outdone by Lev.

During the barbeque at the end of the second training camp, Inuoka is mostly seen in the background eating a great amount of food.

Spring High Preliminary Arc

Nekoma vs. Fukurōdani

Shortly before the match's debut, Inuoka is seen admiring Fukurōdani’s band and cheerleaders with Lev. When Yamamoto attempts to attack Kenma when the setter had tricked him into thinking Lev's sister, Alisa, was watching him, Inuoka is seen holding the ace back to stop him. When Yaku digs an impressive shot from Fukurōdani , Inuoka and the other first years are seen cheering. After Nekoma’s loss, Inuoka is seen attempting to cheer Lev up along with Shibayama.

Nekoma vs. Nohebi

During the match against Nohebi, Inuoka tries to keep the team in high spirits when they look to be concerned about how the match is going but doesn't appear to be very successful until Kenma helps. When with the other first years, he is seen cheering with them as Nekoma scores points or make impressive shots. When both Yaku and Kuroo get injured, Inuoka helps with getting them medical attention. When Nekoma won, he joins in their celebration.

Tokyo Nationals Arc

Nekoma vs. Kiyokawa

With Shibayama and Lev, Inuoka praises the team for their receives against their opponent[4].

Nekoma vs. Sarukawa

During the match's first set, Lev asks Inuoka why an underhand wouldn't make things easier. Inuoka simply answers that it would be difficult to hit and further explains that an overhand pass is faster. Additionally, he cheers for his teammates throughout the match.

Karasuno vs. Inarizaki

Inuoka is referred back to when Ukai requests Hinata to mark Osamu as Inuoka did Hinata during Nekoma's first practice march against Karasuno. However, Inuoka does not seem to notice Hinata doing this as he watches the match. After Nekoma's victory against Sarukawa, Inuoka and Shibayama are impressed at Inarizaki's cheer squad. Seeing Atsumu's jump floater and before that, his silencing of the crowd, Shibayama, and Inuoka are intimidated. Sometime later, Nekoma's middle blockers, which includes Inuoka, get prepared to see Tsukishima block Suna but are proven wrong when Suna scores past him instead. Though the two are impressed by Suna's perfect block nevertheless. Inuoka would later admit to himself that watching this match made him realize that he would never be able to surpass Hinata if didn't practice his bumps.

Nekoma vs. Karasuno

During the game against Karasuno, Inuoka is subbed into the game during the second set to assist Lev in blocking Hinata. This makes Tendō comment on how Nekoma is sending in their "dog". Following Kenma's warning of how Hinata is able to stay in the air longer, Inuoka is able to successfully block Hinata's spike. After Hinata is able to get a spike past the Nekoma blockers, Inuoka is shown to stay on the court instead of being subbed out right away. It's at this time that a flashback reveals that Coach Nekomata had approached Inuoka during Golden Week with the offer of having the first year becoming a wing spiker since Lev was going to be given the regular starting position and Nekomata wanted to add more height to Nekoma's blocks. After this flashback, Inuoka bumps Tanaka's serve, which impresses Kai but he decides not to compliment the rookie opposite yet. This clean bump allows Lev to score, which Inuoka is seen congratulating him for later.

After Karasuno wins the second set, Inuoka is subbed back out and Kai is returned to the court. He is later brought back mid-way into the third set and again focuses on trying to block Hinata. However, he fails at a block when Hinata manages to shoot a spike through the open space between his arms; which Lev refers to as a Bonsai Block. Inuoka later nearly succeeds in gaining a point for Nekoma but Hinata eventually manages to get another point back and is once again subbed out later on. For the rest of the match, he cheers for Nekoma from the sidelines and cheers after Kuroo's short pep talk for the team to win the match. When Nekoma loses, he is shown crying and being comforted by Kai.

Final Arc

Inuoka is seen joining the Nekoma team at Kenma's home and wishes to go to Russia when talking about Yaku living there. He has become a childcare professional[1].


High School Statistics
Game Sense

According by Kenma, Inuoka is the most agile on the team. Because of these skills, Kenma managed to come up with a strategy for him to be the first person to block Hinata. Nevertheless, he was replaced by Lev because of his shorter size. After switching to opposite, in the match against Karasuno, he even impressed Kageyama and Hinata with his speed despite having just entered the court. Initially, he was struggling with passes but after some practice he becomes flexible and proficient at receives and digs.

Jumping Reach: 333 cm


Nekoma High

  • Yūki Shibayama: Inuoka and Shibayama are often shown cheering together for their team on the sidelines and they seem to be on good terms due to them both being first years. Shibayama also admired Inuoka for his height and being able to have gotten a spot as a regular before the Interhigh Tournament begun.
  • Lev Haiba:
    Nekoma s4-e19-1.png
    Despite having being replaced by Lev as a part of Nekoma's starting middle blockers, Inuoka does not hold a grudge against Lev. In fact, because the two are so similar (they both are first-year middle blockers and have similar personalities) they get along quite well. Additionally, they are often seen watching matches together when Lev gets rotated out, and especially during nationals, Inuoka explains a lot of strategic decisions to Lev that he doesn't understand because of his inexperience. During his time on the sidelines, he'd often be seen with Lev and Shibayama. Inuoka has shown hurt from having been replaced as a middle blocker, though he acknowledges it is in for the making of a better team. However, this has motivated him to work harder as an opposite hitter and they show good teamwork when he is subbed in to aid Lev in Nekoma's match against Karasuno to block Shōyō Hinata.
  • Nobuyuki Kai: Because he is the team's regular opposite hitter, Kai was the one tasked to help Inuoka practice his bumps due to their position being known for those. As his newly appointed teacher, Kai was very supporting of Inuoka and was even careful with his words when discussing the rookie's digs as not to hurt his feelings. When watching the match against Karasuno, Kai watched Inuoka successfully perform his duty as opposite and became proud of the rookie's bumps. After they lost, he is seen comforting Inuoka when he cried.

Karasuno High

  • Shōyō Hinata:
    Hinata and Inuoka s1-e12-1.png
    Thanks to their encounter, Hinata stopped being afraid of blockers, which is something he isn't afraid to admit. They first met at the practice match between Nekoma and Karasuno. Though Inuoka noticed Hinata's short height, he did not underestimate him when Hinata warned him not to. Like the rest of his team, he was taken by surprise by Hinata's quick attack. During the match, the two began a rivalry, and Inuoka would soon be filled with the want to stop Hinata when they face each other. Afterward, Inuoka and Hinata began to compliment each other's talents, using mostly their own language of gibberish and excitedly jumping up and down. Later, Hinata remarks that his spikes were blocked because "Inuoka is too awesome!". During the match against Inarizaki, Hinata used Inuoka as an example to block Osamu. They would face off once more at Nationals and despite being opponents, they would still get along well with each other and Hinata showed excitement when he is subbed in. Despite losing his spot as a regular, Inuoka still sees Hinata as a rival.
