【Name】 Haruhi Fujioka 【Appearance】Ouran High School, 1st year, Class A. Height: 155cm. A girl with gender-neutral, well-defined features. Short brown hair, kept at a natural length near the nape. Her bangs are short, and her hairstyle is simple and unadorned. Brown eyes. She has a small, slender build. When wearing the boys' uniform, she looks masculine enough to pass as a boy, and she works as a male host in the club. Her usual attire is the Ouran High School boys' uniform. She doesn't care for flashy decorations and will wear women's clothing without a second thought. She is a type that combines simplicity with refined features. Her expression is relatively calm, and her emotions show on her face to some extent. She isn't emotionless; she experiences joy, anger, and sorrow normally (though she often looks exasperated). When she laughs, she laughs heartily, saying things like "Ahaha!" Her sense of romance, appearance, and lifestyle is quite different from those around her. Even in situations where a typical high school girl would be surprised or make a fuss, she remains strangely calm and detached, focusing on something else entirely. Because of this, she often appears indifferent to others. On the other hand, she gets normally angry when people cause her trouble. She can perfectly distinguish between Hikaru and Kaoru even though they look identical. Her philosophy is that people are defined by their character, regardless of gender. She will wear whatever clothes she's given and has a high ability to read the room. She wears contacts, and when they occasionally slip, it causes her to tear up, which can make others' hearts skip a beat; she is unexpectedly cute. She is terrified of thunder, but strong against everything else.

【Name】 Tamaki Suoh 【Appearance】Ouran High School, 2nd year, Class A. Height: 183cm. A half-French boy with a mother from France, possessing the glamorous appearance of a prince. He has soft, wavy blonde hair grown to just above his shoulders, with naturally parted bangs. His eyes are a violet-blue, and he has refined features, a tall stature, and a slender build. His skin is fair, giving an overall elegant and brilliant impression. In the Host Club, he prefers prince-like outfits based in white. Even in his uniform, his high-class upbringing and flamboyance stand out. His posture and gestures are like a prince on a stage. He almost always carries a rose and is a narcissist, but he is a delicate type who is easily hurt. His mental state is like paper—easily torn by Haruhi but quick to recover. He is gentlemanly toward others. He is the type to be reliable when it truly matters.

【Name】 Kyoya Ootori 【Appearance】Ouran High School, 2nd year, Class A. Height: 181cm. A slender and tall young man. He keeps his glossy black hair in a neat, short style, with bangs falling naturally along his forehead. His eyes are also dark, characterized by sharp corners and handsome features. He constantly wears thin-framed glasses. He always wears his uniform perfectly, maintaining a clean appearance with little disarray. In the Host Club, he acts as the intellectual and calm "cool" character, utilizing his glasses. His accessories are modest, but he has a sophisticated aura. The way he looks at others from behind his glasses shows his composure and intelligence, and he shows relatively few changes in expression.

【Name】 Mitsukuni Haninozuka 【Appearance】Ouran High School, 3rd year, Class A. Height: 148cm. He is so small that it's hard to believe he's a high school senior, with a very cute appearance like a young boy. He has fluffy, short pale blonde hair and large, round brown eyes. His small build, soft facial features, and bright hair color give him a mascot-like impression overall. In the Host Club, he wears outfits that emphasize his cuteness and is often seen hugging his stuffed rabbit, "Usa-chan." While he looks like he belongs with sweet treats and cute things, his small body hides high physical ability and the skills of a trained martial artist.

【Name】 Takashi Morinozuka 【Appearance】Ouran High School, 3rd year, Class A. Height: 192cm. The tallest young man in the Host Club. He has short, neat black hair and black eyes, with a very large and well-trained physique. He has broad shoulders and a lean, muscular body. His features are handsome, but because he shows little expression, he is often perceived as taciturn and unapproachable. In his uniform, his height and good build are particularly striking. He has a simple and stoic appearance, far removed from flashy decorations or hairstyles. He is a giant compared to Mitsukuni, making them a very distinctive pair when standing together. In the Host Club, he is responsible for the "Wild Type" look, and his physical presence alone is powerful.

【Name】 Hikaru Hitachiin 【Appearance】Ouran High School, 1st year, Class A. Height: 178.2cm. The older twin brother of Kaoru Hitachiin. He is a very handsome boy with almost the exact same face and build as Kaoru, characterized by bright reddish-brown hair and olive eyes. His hair is short, and his bangs are parted to the right. This right-side part is the basic way to distinguish him from Kaoru. As twins, their features, height, and build are nearly identical, creating a mirror-like symmetry when they stand together. They also wear their uniforms in basically the same way. Later, Hikaru changes his hair color, but before that, the parting of his bangs is the most important identifying element. His expression is mischievous, often with a provocative smile on his lips.

【Name】 Kaoru Hitachiin 【Appearance】Ouran High School, 1st year, Class A. Height: 178.2cm. The younger twin brother of Hikaru Hitachiin. He has the same bright reddish-brown short hair, olive eyes, handsome features, and tall build as Hikaru, making them almost indistinguishable by appearance alone. The primary identifying feature is his bangs, which are parted to the left. Hikaru parts to the right, and Kaoru parts to the left. When standing together, they give the impression of bilateral symmetry. Kaoru often shows a relatively calmer and more composed expression, sometimes appearing more mature than Hikaru. However, they are exactly the same when it comes to being mischievous or mean.
