Conception Yomi Hirasaka had been working on , which consisted of short stories about everyday life. In developing Boku wa Tomodachi ga Sukunai, or Haganai for short, Hirasaka contrasts the main characters as opposites of the ones in the Light Novel Club which had good relationships to begin with. Hirasaka drew influences from personal experience: "This novel is a story about myself who also had few friends, bad communication skills, negative thinking, lacking life experiences and useless delusional habits." Hirasaka also considers the setting of the stories to be less restrictive. The anime was directed by Hisashi Saito, who had previously directed the fan service romantic comedy Heaven's Lost Property. Hirasaka noted that Itachi's portrayal of the characters in the manga are "all so cute" and "their faces are full of life", especially the expressions of the heroines Yozora and Sena.
Plot Kodaka Hasegawa, a transfer student to St. Chronica's Academy, has found it difficult to make friends because of his mix of brown-blond hair (inherited from his deceased English mother) and fierce-looking eyes that make him look like a delinquent. One day, he accidentally comes across the equally solitary and very abrasive Yozora Mikazuki as she converses with "Tomo", her "air" (imaginary) friend. Realizing that they lack social lives and skills, they decide that the best way to improve their situation is to form the , "an after-school club for people with no friends like themselves". Other students with various backgrounds join the club: Sena Kashiwazaki is an attractive but arrogant idol who has no female friends and treats the boys as her slaves; Yukimura Kusunoki is an effeminate underclassman who idolizes Kodaka and strives to become manly like him; Rika Shiguma is a genius scientist with a perverted mind; Kobato Hasegawa is Kodaka's little sister who generally cosplays as a vampire; and Maria Takayama, a ten-year-old foul-mouthed nun who serves as the club's advisor. The story follows their adventures as the club tries out various school and outside social activities as practice for making friends.
Characters
Neighbors Club is the viewpoint character of the light novels; he is a transfer student who has been unable to make friends in his first month at St. Chronica's. He and Yozora Mikazuki start the Neighbors Club with the purpose of learning how to make friends and how to act in social situations. He has a gentle and balanced personality; but his unusual spotty-blond hair color, inherited from his late English mother, leads classmates to assume he is a violent and abusive delinquent and to spread defamatory rumors about him. Because of his reputation, Kodaka has become accustomed to conflicts and having to defend himself. Prior to the series, Kodaka often had to move because of his father's work as an archeologist. He has few memories related to home life, and no friends besides a single childhood friend from ten years previous, whose name eludes him at first. He later discovers that his friend 'Sora', whom he thought to be a boy, is in fact Yozora. He does not show any romantic intentions towards anyone in the club until Sena's confession, which prompts him to reveal that he has been in love with her since their first meeting. Correction: In LN 12 Chapter 51–53, Kodaka/Sena's father is under the impression that Kodaka and Sena are in a relationship and asks how they are progressing, and Kodaka seriously denies this in front of the group. Sena explains to Kodaka in private that she may have misled her father by exclaiming that with the Wonderland tickets she will be able to make Kobato her younger sister, and also tells Kodaka that their fathers betrothed them before they were old enough to remember. It was "a formal contract with their thumbprints and everything". They both smile. Kodaka then says his dad probably doesn't remember, because he wasn't told any of this, and it doesn't matter anymore because "that was when we were kids". Neither confess. When Sena and Kodaka return to the group, they try to keep a low profile but are eventually confronted with the question whether they are engaged. They do not respond, but Yozora is already questioning Rika which is closer - childhood friends or a betrothed couple. Kodaka thinks to himself that this is too cruel to Yozora. They both then say the engagement doesn't matter and to get back to the club's activity - filming. Kodaka is voiced by Ryōhei Kimura, and by Jerry Jewell in English. For the live-action film, he is portrayed by Kōji Seto. is a black-haired girl who is described as not having much going for her other than her looks. She is a gifted student who often argues with Sena, who consistently scores better than she does on their exams. Yozora is verbally abusive towards people in general, not to mention the other members of the Neighbors Club, especially Yukimura, whom she fools into working for the club as a crossdressing cosplay maid. Ten years prior to the start of the series, she and Kodaka ("Taka") were childhood friends, but because she had short hair and wore a cap, Taka mistook her for a boy and called her "Sora". The day before he moved away, she wore a skirt to reveal the fact that she was a girl, but was too embarrassed to meet with him. Kodaka was going to tell her of his imminent departure at the meeting, but since it did not happen, it appeared to Yozora that she had been abandoned, thus exacerbating her distrust of others. At the start of the series, she recognizes Kodaka as her childhood friend. When Kodaka discovers her talking to her imaginary friend "Tomo-chan", she creates the Neighbors Club in order to renew their friendship. Kodaka does not recognize her as Sora until later in the story after she cuts her hair short. In the anime, Yozora is voiced by Marina Inoue in Japanese and by Whitney Rodgers in English. In the live-action film, she is portrayed by Kie Kitano. is a blonde-haired girl who is described as "perfect in every way except for her personality." The daughter of the school's chairman, Sena shows a dislike of all things ordinary. She is both attractive and academically successful, but her arrogance precludes her from making female friends, and she treats her male classmates as slaves. She enjoys playing video games, particularly bishoujo (games where the main character tries to win over a girl) because they allow her to make female (if virtual) friends, although some of the games have embarrassing adult content. She does not get along with Yozora, who calls her . Although she originally joins the Neighbors Club to learn how to make friends, she develops feelings for Kodaka after he scolds her for inciting an incident during their trip to the swimming pool. When it is revealed that, fourteen years previously, her father arranged a marriage between her and Kodaka (his best friend's son), Sena confesses her feelings and proposes to Kodaka. In the anime, Sena is voiced by Kanae Itō in Japanese and by Jad Saxton in English. In the live-action film, she is portrayed by Mio Ootani. is a junior high student at St. Chronica's Academy. She is very close to her older brother Kodaka, and behaves in a jealous and clingy way whenever he does not give her attention. Kobato cosplays as "Reisys V. Felicity Sumeragi", an ancient vampire, her favourite character from the anime Iron Necromancer, by wearing gothic clothing and a red contact lens, drinking tomato juice (blood) and speaking in affected formal language, although Kodaka still treats her as a little sister by making her eat her vegetables and take a bath. When she gets emotionally worked up, she reverts to a strong Kyūshū accent. She joins the Neighbors Club to spend more time with Kodaka, and develops a rivalry with Maria, who is closest to her in age. When the club visit her school's festival to watch her class film, it is revealed that she is quite popular, but has refused to make friends with her classmates despite their efforts to befriend her. In the anime, Kobato is voiced by Kana Hanazawa in Japanese and by Alison Viktorin in English. In the live-action film, she is portrayed by Sayu Kubota. is an effeminate schoolmate who is first introduced as Kodaka's stalker. A gullible student with low self-esteem, Yukimura sees Kodaka as a romantic and masculine outlaw who lives life the way he wants to, and eagerly pledges to become his "underling" in order to learn how to become manlier. Despite claiming to be a boy, Yukimura dresses in girls' clothes, as he takes to heart Yozora's flippant comments about masculinity and clothing. Later in the story, Kodaka discovers that Yukimura is actually a girl, even to Yukimura's own surprise. In the anime, Yukimura is voiced by Nozomi Yamamoto in Japanese and by Ashleigh Domangue in English. In the live-action film, Yukimura is portrayed by Sara Takatsuki. is a first-year genius-scientist student whom the school has given a special research room and excused from attending classes. She is an illeist who always addresses herself in third person, never in first person. She becomes interested in Kodaka after he rescues her from the lab after one of her experiments goes disastrously wrong. Although she wears glasses and seems serious, she is the most eccentric and sexually forward club member, and often converts innocent remarks into something perverted. She enjoys reading BL (boys' love) (self-published magazines), and is especially aroused by stories that involve intercourse between mecha. In the anime, Rika is voiced by Misato Fukuen in Japanese and by Alexis Tipton in English. For the live-action film, Rika is portrayed by Mao Kanjō. is a ten-year-old nun and the club's staff adviser. She is very rude and crass, and often uses a variety of expletives when annoyed. After Kodaka starts making her packed lunches, she becomes very affectionate with her new-found onii-chan (big brother), much to Kobato's annoyance. She is easily manipulated by Yozora, who gets her to perform menial tasks by framing them as things adults would do. Volume 8 of the light novels has a story where her teaching position is challenged. In the anime series, Maria is voiced by Yuka Iguchi in Japanese and by Kristi Kang in English. For the live-action film, Maria is portrayed by Momoka Yamada.
Supporting characters is Sena's father and the president of St. Chronica's. As a friend of Kodaka's father, he arranges for Kodaka and Kobato to attend the school. He is embarrassed by the unusual pronunciation of his first name, which would normally be "Tenma". He often badmouths Kodaka's father, but only because he truly values him as his best (and more or less only) friend. He seems intent to betroth Sena to Kodaka, often saying that he considers Kodaka to be "a man I can entrust Sena to", after misunderstanding Sena's intentions to make Kobato her younger sister. In the anime series, he is voiced by Ryōtarō Okiayu in Japanese and by Brandon Potter in English.
