oikawa & Iwaizumi🪼٭★٭˚∘•

Oikawa has dark brown hair that is swept outwards and eyes of the corresponding color. Many people find him attractive, to the point where several girls follow him around. Oikawa frequently smiles or 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 winking.

Oikawa is of decent height for a volleyball player, standing just over six feet. While on the court, Oikawa wears the standard aqua and white Aoba Johsai High uniform emblazoned with the number one. He also wears dark gray athletic shoes with blue details. 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 practices, he wears an aqua shirt and white shorts. During the finals match between Karasuno and Shiratorizawa, Oikawa is shown to wear glasses but it's unknown if he truly needs them or not.

Post-timeskip, Oikawa appears mostly the same although his hair is noticeably shorter, and he has developed a slightly more muscular build.Despite his flirtatious nature (which makes him famous amongst female students, much to Tanaka and Nishinoya's envy) and childishness, 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

Iwaizumi has dark, spiked-up hair, and thin eyebrows. His eyes are dark brown in the manga, olive green in the anime adaptation, and grey in the Haikyuu!! smartphone game. His hair is black in the manga and in the Haikyuu!! smartphone game, but dark brown in the anime. More often than not, he's shown to hold a serious or irked expression.

While playing volleyball, Iwaizumi wears a standard Aoba Johsai uniform with number four on it. He is otherwise shown wearing an Aoba Johsai school uniform consisting of khakis with dark brown details, a lavender-colored button-down shirt, a dark red tie, and a white blazer. Iwaizumi's uniform appears to be missing the cream-colored vest that goes with the rest of the uniform and appears to be slightly disheveled, with his tie loose around his neck and his shirt left untucked.

In the anime adaptation, Iwaizumi is seen wearing an outfit which consists of a pair of jeans with an oversized dark blue denim jacket over a grey hoodie.

Post-timeskip, Iwaizumi's appearance has changed very little with the only exception being his hair is slightly shorter.Iwaizumi is a stubborn but reliable teammate, often filling in Oikawa's spot as a morale booster if needed. He acts supportive to all, including Tobio Kageyama, and calls Oikawa out for his childish antics. He often resorts to violence with Oikawa whenever he teases or provokes him, but this does not change the fact that he cares immensely for him; as shown when he makes an effort to stop Oikawa from either working too hard or losing confidence.

Iwaizumi's firm-yet-caring attitude has led some members of the Aoba Johsai team to look up to and respect him. His underclassmen often gravitate towards him, and he is seen giving calm and light-hearted advice to Kindaichi, which can contrast to how he treats Oikawa. He is also very respectful and does not treat his rivals coldly, as Kageyama still treats him respectfully and Iwaizumi has acknowledged his skills.
