Lucky Star: Main characters

Konata Izumi

Konata is, more by default than anything else, the "leader" and the shortest of the main characters. Nicknamed "Kona-chan" (こなちゃん?) by Tsukasa, she is an eccentric but friendly and outgoing girl, with a mischievous yet good-natured sense of humor. She can be smart, but she hates studying, thus her grades are a bit uneasy. However, she is an expert at pulling "all-nighters". In contrast to her studying habits, she loves video games, to the extent that she can compete against Kagami Hiiragi on trivia-based games. In addition, she loves anime, which is also due to her father, Sōjirō Izumi's influence,] along with the games. Her father buys adult games for himself, so she is able to play and enjoy them. In fact, when she became eighteen, Konata was overjoyed, since she could now go buy and play adult games legally. In the anime, Konata constantly refers to or parodies several popular games, anime, and manga (much to the annoyance of Kagami). Both of her voice actresses for the animated version, Aya Hirano for the Japanese version and Wendee Lee for the English version, are in fact the same people who voiced Haruhi Suzumiya in The Melancholy of Haruhi Suzumiya anime; other voice actors from the same series make guest appearances during the course of Lucky Star.

In order to fund her interests, Konata had a part-time job at a cosplay cafe in Akihabara. In online gaming, she played a male fighter type character, that gets married to a female fighting character that is actually a guy. She often plays late into the night, hence why she tends to fall asleep in class, which makes her a frequent victim to her homeroom teacher, Nanako Kuroi. Ironically, Ms. Kuroi was also part of Konata's team in the same game. Konata rarely eats a "normal" Japanese lunch, as she frequently eats only a chocolate cornet.

Her physique is smaller than average when compared to her peers, which she claims hasn't changed since she was in the sixth grade. She is ambidextrous, in contrast to the mostly left-handed main cast. She has long, blue hair which comes down to her calves with a large ahoge, sleepy eyes, a catlike smile and a beauty mark under her left eye, just like her father. Her mother, Kanata Izumi, died when she was an infant, and she has lived alone with her father since. In her third year of high school, however, her cousin, Yutaka Kobayakawa, came to live at her house, giving a total of three people in the Izumi residence. Although Konata spends most of her time playing games in her room, she has a darker skin tone, like her father's. Konata placed seventh in 2channel's SaiMoe 2007 contest, came in second place in the category of "Best Female Character" in the thirtieth Anime Grand Prix, and ranked third in Newtype's "Top 10 Female Characters of 2007" poll.

Miyuki Takara

Miyuki is a young lady from a wealthy family who is beautiful, smart, and well-mannered. She always uses extremely polite Japanese, even when talking with her closest friends. She was the class president for her grade level in her first year, at the same time that she became good friends with Kagami. Now Miyuki is in the same class as Konata and Tsukasa, and is nicknamed "Yuki-chan" (ゆきちゃん?) by Tsukasa. Miyuki's classmates often rely on her for help with their studies, and she is often shown giving impromptu but highly-detailed, encyclopedic definitions or explanations on diverse and obscure matters, prompting Konata to once call her "Miwiki". She is shown being one of the top three best students in her grade for the semester.

She is described as a stereotypically friendly meganekko, or glasses-wearing girl and is the tallest of the girls. She is scared of contacts, and of putting them in her eyes, thus why she wears glasses. Her vision is less than 0.1 (20/200), though it had been good until elementary school, when she began reading books in the dark after her mother dozed off while reading to her in bed. She likes to read books, but does not read light novels. Miyuki loves to sleep, and she always goes to bed fairly early. She hates visits to the dentist, but frequently has to go to fix a loose crown or because of tooth decay. Due to her embodying such a large number of moe archetypes, Miyuki is the frequent-victim of Konata's playful bouts of verbal sexual-harassment. She is seen less often than the other three main characters.

Kagami Hiiragi

Kagami is the older fraternal twin sister of Tsukasa Hiiragi. In school, her grades are excellent, as she studies very hard, and she was elected class president in her first year. She is in a different class than Konata Izumi and Tsukasa, but she frequently comes to their class during lunch time to eat with them. Additionally, Kagami chose the humanities stream in her second year, so that she could be with her friends, but she was the only one separated into a different classroom; the same occurred in her third year. Kagami, occasionally referred to as "Kagamin" (かがみん?) by Konata, is a bit egotistical, and not as good a cook as Tsukasa. Konata loves to irritate her, and their arguments act as one of the main factors of comic relief throughout the series. Kagami is usually annoyed by Konata's constant references to her otaku interests, but usually has an idea on what she is saying.

Kagami's physique is average. However, she is usually concerned about her weight, counting every kilogram she gains or loses. Kagami likes to eat sweet food and she is often seen eating sweet food at night, such as chocolate Pocky sticks. Despite her concern about her weight, she has no willpower controlling her eating habit, resulting in an "eat now, fret later" attitude. She has long, purple hair with a ribbon tied into bunches, and unlike Tsukasa, has sharp eyes. Kagami is the quintessential "tsundere"; she on one side can be the straight and intolerant type however, she is prone to become shy and lonely at times. Kagami is constantly attempting to hide the fact that she has a deep sense of attachment to her friends, especially Konata. She also seems to take a twisted delight in mocking Konata's smaller-than-average physique, her lack of motivation and her tendency to be a troublemaker, which usually results in Konata becoming very defensive. In spite of all this, she really does care about Konata, and is almost always willing to go places or do favors for her.

Similarly to Konata, Kagami likes video games, but plays a different genre than Konata: side-scrolling shooters. She loves to read light novels, but is lonely, as no one around her has the same interests as her (though she is implied to have a knack for anime, since a stuffed Bonta-kun doll from Full Metal Panic! can be seen in her room). Both Kagami and Tsukasa are left-handed. Kagami shares the name of her creator, Kagami Yoshimizu, and according to the creator, Kagami was his pen name in his school days, and had her personality thought out long ago. Kagami became the 2008 Anime Saimoe Tournament's champion with her sister Tsukasa being runner-up.

Tsukasa Hiiragi

Tsukasa is the younger fraternal twin sister of Kagami Hiiragi and lives in a six-member family household as the youngest member. She is in the same class as Konata Izumi. She isn't good at studying or at sports, but excels in cooking. Tsukasa often depends on Kagami for help on her homework, like Konata, but their reasons are different: Tsukasa easily forgets her assignments, while Konata is just too lazy or preoccupied with her hobbies to do them herself. Unlike some of the other characters in the series, Tsukasa has not shown any particular interests in video games and anime, but she does like the Sgt. Frog series.

Tsukasa's physique is a little smaller than average. She has short, purple hair with a ribbon like a head band in it. Her eyes are droopy and she is portrayed as a stereotypical klutz. Tsukasa once received a mobile phone for her birthday, but didn't have much luck with it, as the phone was taken away by using it in class and later mistakenly ruined by putting it in the laundry, along with her skirt. Once, she left instant yakisoba alone after pouring hot water in it, only to come back later discovering there was no water left to drain.[15] Unlike most of the cast of Lucky Star, Tsukasa is a heavy sleeper, and cannot wake up at a set time, even when someone is present to do so. Like her sister, Tsukasa is left-handed.
She can be mistaken for cosplaying as Akari Kamigishi from To Heart when she wears her autumn school uniform, which is pointed out twice in the anime: once, when Konata gave her the actual uniform used in the To Heart anime for her birthday (while giving Kagami the "Brigade Chief" armband usually worn by Haruhi Suzumiya), and the second, when two people stopped her at Akihabara to take her picture, much to her embarrassment.
