Miya has a light-coloured fringe similar to Shirabu's. It appears to be dyed, as he also has a darker undercut. His eyebrows are a dark colour, most likely his original hair colour. His eyes are large and hooded and droop slightly.
Miya is a provocative, but carefree person. Though he likes to annoy people, he sometimes gives offhand compliments. He's often shown with a lazy smile on his face, but he can be arrogant and condescending. Although, he can be easily annoyed when someone interrupts his serves by cheering for him, and will get frustrated easily when his serves miss. It is also noted by his twin brother, Osamu, that his mental age drops by five years whenever he's in the middle of a game.
According to his brother Osamu, he doesn't listen to what you tell him, he doesn't returns what he borrows, and he's a habitual liar.
Not much is known about his background, but it's been noted that he speaks in a Kansai dialect. Since Miya was invited to the All-Japan Youth training camp, he's at a very high skill level. His team placed 2nd at the Interhigh, and are the second seeds at the Spring High.
Tokyo Nationals ArcEdit
Preparation for Nationals
He's invited to the All-Japan Youth Intensive Training Camp. During the first practice match, when Kageyama messes up, Miya chuckles lightly and later, seems to focus a lot of his attention on the first year.
Sometime later, during a break, he approaches Kageyama as the latter was talking to Hoshiumi. After Kageyama tells Hoshiumi that he's not really affected by his jumping power, Miya laughs and calls Kageyama a cool and collected person. He then bluntly tells the first year that he initially thought Kageyama was a badass, but he can now see that Kageyama's just a goody-two-shoes. This annoys the latter, who glares at Miya hostilely.
The final practice match, Miya tosses to Kageyama for the first time. Kageyama easily hits it and tells Miya later that his tosses are easy to hit. Arrogantly, Miya replies that people who can't hit his tosses are scrubs. He then asks Kageyama if he enjoys spiking more than setting because Kageyama seems to be annoyed when he sets. Kageyama doesn't understand and stresses that he's a setter, and Miya leaves it at that. Kageyama suddenly reminds him of what he said about his being a goody-two-shoes, and Miya replies that he just means Kageyama is obedient and honest.
As the players head home, Miya waves to Kageyama and tells him that they'll meet again at nationals.
Miya watches Karasuno's first match against Tsubakihara and notes that Kageyama's completely different from when he was at the camp. He then turns to Hinata, having seen his jumping power and speed, and wonders who he is.
Facing Karasuno in the second round, Miya is the first to serve. He silences Inarizaki's orchestra, and hits a powerful spike serve that paints the line between Tanaka and Nishinoya. He then glares at two girls who cheered him on during his first serve, displeased with them for interrupting him while serving. He misses his second serve.
Miya is the best high school setter in Japan. Though he hasn't been shown setting powerful tosses, it's been shown that his tosses are very easy to hit, never wavering and never off. Miya's tosses create the illusion that the spikers have improved. He won the Best Server award at both the middle school meet and the Interhigh.
He is known as the "Dual Wielder" due to being capable of using jump floaters and spike serves.
Like Kageyama and Hinata, he is capable of perfectly coordinating with his twin brother Osamu Miya that they can pull off God-Fast Quick. However, according to himself, it is not as accurate as Kageyama and Hinata's version. On the other hand, the only person who managed to stop it so far is Tsukishima.
Kageyama took an immediate dislike to Atsumu when the second year called him a goody-two-shoes, but Atsumu later explained that he was referring to how Kageyama was diligent, honest, and obedient; it's still unknown though if Atsumu intended his explanation to be a compliment or another derogatory comment. Despite this, Kageyama doesn't hold the grudge for long. Atsumu seems to be amused by Kageyama for some reason and calls him "Tobio-kun".
During the match against Karasuno, we can see his twin brother. They have a freak quick not unlike Kageyama and Hinata's.
