Domyouji Tsukasa is the leader of the F4. At the beginning of the series, he is Makino's biggest enemy, but as the story progresses, he becomes her love interest. Tsukasa is the heir to Domyoji Enterprises, and his family is extremely rich. They own various houses around the world, including an actual island, a house in Canada, and a house in New York City where his parents stay. Domyouji grew up somewhat lonely, as his parents were always overseas, and his sister—as loving as she could be—was either busy studying or, later in life, married and moved to Los Angeles. Also, his mother, Kaede, is cold to him, and although she loves him, wants to control his life. Tsukasa sometimes calls her "the old hag" and "witch". Before he met Makino, he was violent and ill-tempered, but after he became loyal and nice. As Tsukasa first started off being hard and tough to get though to; the author of Hana Yori Dango showed us thoughout the anime and manga that anyone who starts off being hard can also find their soft side because of love and that is shown though Tsukasa Domyouji.
Birthday: January 12 Sign: Capricorn Blood Type: O Height: 153 cm Class: Freshman With a principled competitive nature and natural aptitude to excel at an exceptional range of athletic activities, Itsuki’s direct mannerisms and masculine habits would have observers brand her as the classical embodiment of a tomboy. Though capable of mastering any sport she participates, Itsuki would readily declare that soccer is the most enjoyable and rewarding. At times her dedication can be borderline obsessive, as it is not uncommon for her to spontaneously start dribbling or perform warm-up exercises to pass idle time.
Manda is the personal summon of Orochimaru. Manda was the largest snake in the world, before being recently out-sized by his clone, Manda II. He easily towers over buildings, trees, and large rock formations. Due to his length, he is even larger than Gamabunta and Katsuyu, easily coiling around Katsuyu and having more length behind him, and he could open his jaws wide enough to swallow Gamabunta whole. He is colored purple, and has black rings running down intervals on his body. He has massive fangs, though they are arranged in a way similar to that of a constrictor snake instead of a viper or other venomous snake species, presumably carrying venom in them from the way they were designed, and green eyes. He also has four horn-like protrusions on his head.

Kazuya is another one of Tsukushi's childhood friends. He enrolls at Eitoku after his family comes into money through some real-estate deals. The other students at Eitoku draw a sharp distinction between Kazuya's "new money" and their "old money." The F4 in particular mention this difference fairly often. Tsukushi is both relieved to have a friend at Eitoku, and worried for Kazuya's safety if he continues to hang around her. She is particularly worried about Domyoji, who clearly considers Kazuya a romantic threat. Kazuya is fiercely loyal to and harbors romantic feelings for Tsukushi, but also relatively clueless and not very quick to pick up on things. He is not featured in the drama. (Source: Wikipedia)
Another member of F4, Sojiroh is quiet and very interested in the tea ceremony, which is his family's business. For the most part, he and Mimasaka usually work to keep the peace within the group and following Domyoji. In season two, he reunites with his first love, whom he had believed had only loved his brother. Later he learns that she had truly loved him, but the relationship is unsalvageable (in the manga they both recognize that they missed their one chance to be together, and in the drama she has become engaged to someone else). Makino's close friend, Yuuki has feelings for him and it is uncertain whether he feels the same way. He is also one of the two playboys in the F4. (Source: Wikipedia)
