Gender: Female Age: 17 Stats: 155cm, 45kg Affiliation: Ouran Academy 1st Year Class A, Ouran High School Host Club Type: Natural Likes: Sushi, Ramen, Strawberries, Fatty Tuna A beautiful girl with an androgynous appearance. She is indifferent to her looks and gender, wearing whatever clothes she is given—whether men's or women's—without a second thought. Her personality is so easygoing and blunt that she is called a "natural," and she is completely oblivious to the romantic feelings those around her have for her. Even toward Tamaki, who loves her quite overtly, she treats him only as a bothersome, foolish senior or a doting father figure. However, she is quite sensitive to the feelings of others; she is the only person who can accurately tell the Hitachiin twins apart, something no one outside the Host Club could do before. Haruhi uses polite speech and addresses everyone except her classmates, Hikaru and Kaoru, as "Senpai." She occasionally stabs Tamaki with unintentional verbal daggers, but she is fundamentally calm and kind. Surprisingly, she has a great sense for styling casual clothes. She joined the Host Club to pay off the debt from breaking an expensive vase.

Gender: Male Age: 19 Stats: 148cm, 41kg Affiliation: Ouran Academy 3rd Year Class A, Ouran High School Host Club Type: Loli-Shota Likes: Cake, Candy, Strawberries Commonly known as Honey-senpai. He always has something sweet in his mouth and carries around a stuffed rabbit named Usa-chan, a handmade gift from his grandmother whom he loved dearly. He often talks to the doll, saying things like "Usa-chan says..." When he wakes up from a nap, his personality becomes megaton-level terrifying. His authority as a senior is quite weak. In reality, he is a master of all martial arts, including hand-to-hand combat and weapons. Despite his cute appearance, his combat prowess is top-tier. Because of his cute looks, Honey-senpai is very popular in the Host Club, but since most of that popularity is based on maternal instincts, few women harbor actual romantic feelings for him. As the second oldest member, he is surprisingly perceptive and was the first to notice the feelings the club members have for Haruhi (feelings they haven't even realized themselves). However, he shows no sign of intervening and simply enjoys watching the situation unfold.

Gender: Male Age: 18 Stats: 183cm Affiliation: Ouran Academy 2nd Year Class A, Ouran High School Host Club (President) Type: Princely Likes: Hot pot, commoner food, Haruhi (unaware) The founder and president of the Ouran High School Host Club, boasting the highest request rate from female fans. As the son of the Chairman, he possesses a prestigious family background, academic excellence, and stunning looks. His position is the Prince. He is essentially a handsome, idiotic prince with a narcissistic streak. Yet, he is a contradictory person who can be remarkably perceptive at times. He mistakenly believes his feelings for Haruhi are the love of a father for his daughter (though he is not actually Haruhi's father).

Gender: Male Age: 19 Stats: 192cm Affiliation: Ouran Academy 3rd Year Class A, Ouran High School Host Club Type: Wild Likes: Natto Commonly called "Mori-senpai" by juniors and "Mori" by his peers. Though he doesn't stand out much, he is shown to be quite fond of and protective of Haruhi Fujioka. He serves as a support for Honey-senpai (Mitsukuni Haninozuka); in fact, Honey's personality is such that he seems unable to function in daily life without Mori. He is silent and stoic, but possesses a delicate personality despite his large frame.

He is a classmate of Haruhi Fujioka. He often plays up the "forbidden brotherly love" act with Hikaru to fuel the fantasies of female guests. He is skilled at interpersonal relationships and expressing emotions, and is surprisingly calm in daily life, though his mischievous nature remains.

Gender: Male Age: 17 Stats: 178.2cm Affiliation: Ouran Academy 1st Year Class A, Ouran High School Host Club Type: Little Devil The elder of the Hitachiin twins. He is a classmate of Haruhi Fujioka.

However, one person managed to tell exactly who was who without looking at their hair (that person being Haruhi Fujioka).
