Sakusa Kiyomi

The attitude of students, fans and others around
Itachiyama's classmates and fans treat Sakusa with great respect and interest: he is popular as the team's star, and many come to support him.
Other schoolchildren and tournament participants often see him as a "cold genius": his demeanor, his mask off the court, his avoidance of crowds, and his strict standards create the image of a detached and demanding person. Some perceive this as arrogance, others as a sign of a serious approach to the game.
Coaches and organizers recognize his level and invite him to elite training camps—this in itself is a marker of high trust and recognition of his talent.
Why is the attitude like this?
The relationship with Sakusa is built on a contrast: on the one hand, he is incredibly talented and hardworking, on the other, he is straightforward, blunt, and demonstratively distances himself from excessive emotionality and "imperfect" situations (including due to mysophobia and a desire for perfection). Because of this, some admire his professionalism, while others find him difficult to communicate with.

Attitude of teammates
Motoya Komori (his cousin and close confidant) knows Sakusa's quirks well, worries about how he'll fit in with the group, and understands his perfectionism. He's the only one truly close to Sakusa and sees him not only as a prickly genius but also as a person with his own weaknesses.
Other Itachiyama players view Sakusa as the team's undisputed strength, but his straightforwardness and bluntness can be off-putting. They value him for his skill, but don't always understand his personal quirks (like his mysophobia).

Attitude of rivals
Wakatoshi Ushijima - they have a respectful rivalry: both are top aces, and each acknowledges the other's strength without further ado.
Kotaro Bokuto views Sakusa as a serious threat and a target for revenge: he wants to defeat him specifically because Itachiyama has beaten Fukurōdani on numerous occasions. Meanwhile, Sakusa often ignores Bokuto's emotional outbursts, which further fuels his opponent.
Tobio Kageyama is impressed by Sakusa's technique, but tension arises between them due to their different approaches and because Kageyama directly hurts Sakusa's feelings.
Shoyo Hinata tries to be respectful with Sakusa, although he is not prone to warmth and is quick to point out mistakes.

Rules
Overall, they were typical of a sports school with a strong emphasis on discipline and team spirit. Students were expected to adhere to a strict schedule: arrive to class on time, respect teachers and older peers, and take good care of school property. Particular attention was paid to preparing for competitions—regular training, following the coach's instructions, and maintaining good physical fitness were required. Overall, the school atmosphere was quite rigorous: students were expected to take their studies and athletics seriously.

School and sports uniform
There's an important nuance here: Itachiyama doesn't have a standard everyday school uniform in the traditional sense (like the gakuran or sailor suit in real Japanese schools). However, the school's volleyball team does have its own recognizable tracksuit.

This is what it looks like:

The volleyball uniform is yellow and green. The school name, "Itachiyama," is written on the back.
Volleyball equipment separately: yellow shorts and a jersey. The jersey has a yellow-green gradient at the top, a black stripe in the middle, and a white stripe at the bottom.
On the back of the jersey, next to the player's number, the word "Itachiyama" is also written in black font.

Itachiyama is one of the strongest high school volleyball teams in Japan, the Tokyo champion and the top seed in the national Spring High tournament. The team is renowned for its powerful offense and solid defense, making it extremely difficult to take a set from them.

Kiyoomi Sakusa is the team's ace, one of the strongest forwards in the country. He is tall (189 cm), slender, with very neat, distinct features. He has black hair and cool, attentive eyes—this emphasizes his calm, game-focused nature.

Motoya Komori is the libero. He's noticeably shorter than Sakusa and has a more compact but strong build, making him ideal for serving and defending. Komori has short dark hair and a rather open, friendly face—reflecting his role on the team: he's the defensive link, requiring alertness and speed.

Iizuna is disciplined, strictly follows his coach's plan, and doesn't seek personal glory: what matters most to him is the team's cohesiveness. In stressful situations, he doesn't panic, but focuses on his role, making him a valuable asset to the defense.

The general character of the Itachiyama team
Team Itachiyama is a combination of individual skill and strict discipline. Their style is built around strength and precision: they emphasize powerful attacks and solid defense over risky moves. The players are accustomed to high demands and view each practice as a necessity, not a choice. A respectful yet competitive atmosphere reigns within the team: everyone strives to improve without hindering others. They are not prone to excessive emotion on the court—their strength lies in concentration, calculation, and the ability to maintain the pace even in the most intense matches.

Perfectionism and high standards. Sakusa strives for perfection and tolerates no unfinished business: if he starts training, he won't stop until he achieves the desired result. He is demanding not only of himself but also (indirectly) of those around him—any imperfection irritates him.
He's realistic and analytical. He harbors no illusions and prefers to rely on facts: he asks a lot of questions to thoroughly understand the situation. On the court, he instantly identifies the strengths and weaknesses of his opponents and adapts his play to them.
Mysophobia and caution. Sakusa is very sensitive to issues of cleanliness and germs: he wears a mask outside of play, avoids crowds, and tries to minimize contact with anything he considers "contaminated." This isn't just a quirk, but an essential part of his behavior. Focus and restraint. Outwardly, he appears calm and collected, almost detached. He's not prone to excessive emotions, doesn't like to draw attention to himself, and stays away from noisy groups.
Competitiveness and pride. Despite his outward composure, Sakusa reacts sharply to strong opponents: if he sees someone as a threat, he focuses on that player and strives to surpass them. He expresses respect for his opponents through extreme composure and a desire to win fairly but decisively. He dislikes chaos and uncertainty. He is uncomfortable in crowds and in situations where everything unfolds spontaneously. He prefers clear boundaries, predictability, and control over what he can control.
Dedication. Volleyball isn't just a pastime for him, it's a serious pursuit. He's willing to spend hours perfecting even the smallest details and doesn't give up until he reaches a level he's comfortable with.

Clothing preferences
Kiyomi Sakusa is a perfectionist and very focused on the game, so he chooses practical equipment. He primarily wears the volleyball uniform of his team (Itachiyama): a jersey and shorts in the club's signature colors, plus standard volleyball shoes. He is known for his attention to detail: he uses high-quality knee pads, tape, and other protective gear, choosing everything so that nothing interferes with his technique. Off the court, he prefers a discreet, minimalist style without flashy details—he values ​​functionality and comfort over fashion.

Food preferences
In the "Volleyball!!" canon, Sakusa doesn't have any pronounced food preferences, but his personality likely favors a balanced diet suitable for an athlete: plenty of protein, complex carbohydrates, and minimal excess sugar and heavy foods. He likely chooses simple, tried-and-true dishes that provide energy and don't cause discomfort before matches—for example, rice with chicken, fish with vegetables, and protein snacks.

Hair. Black, wavy.
Moles. Two on the right side of his forehead—one of the most noticeable details of his appearance.
Build: Slender, yet above average height (189 cm).
Mask. Outside of matches, Sakusa often covered his mouth with a white mask. This was due to his fastidiousness and squeamishness. He didn't wear masks as a child; the habit developed in middle or high school.
Shoes. He wore yellow sneakers with black inserts.
