Sō Inuoka (Japanese:
Inuoka has a rather large build for a first-year 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 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.
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. Inuoka almost always gives off a very positive and happy vibe when he is around. He is also shown to be very caring and encouraging towards his teammates.
Not much is known about Inuoka's background.
In the practice match against Karasuno, Inuoka is chosen to follow Hinata to block his spikes since he was the best fit for it. After getting used to Hinata's spikes, Inuoka is able to completely block them.
As stated by Kenma, Inuoka is the most agile on the team. However, once Lev comes in, his overall skill isn't enough to retain his spot as a regular. Like the rest of his team, he is flexible and really good at receiving.
Jumping Reach: 333 cm
He's shown to hang out with Shibayama often.
The two seem to have a slight rivalry, with Inuoka stating that Lev has been blessed with too much (in terms of height) and that he won't lose to the latter as Lev is the reason Inuoka is no longer a Nekoma regular. In the OVA, Inuoka is shown to be supportive of Lev in his goals of becoming Nekoma's ace.
