Age: 13-14 Birthday: October 18 Kodaka's younger sister; she is a student in middle school, but nonetheless joins the club. She is very close to her brother, who she calls "An-Chan", and behaves in a jealous and clingy way whenever she feels that he is not giving her the attention she deserves, to the point where it is obvious that she has a brother complex. She sees Maria as a rival for Kodaka's brotherly affections, so she often gets into fights with her. She has a penchant for darkness, vampires and the macabre ever since she started watching an anime called Full Metal Necromancer. As a result she often speaks in an affected fashion, and claims to be known as "Reisys VI Felicity Sumeragi", an ancient vampire who has lived for ten thousand years, but this façade quickly breaks down when she gets emotionally worked up and she speaks in a strong KyÅ«shÅ« accent. Indeed, her behavior does not for the most part differ from that of a regular girl (procrastinating with her homework, staying inside when it is hot, etc.) which Kodaka points out, causing her to be embarrassed and slightly lose character.

Age: 16 Birthday: June 13 Blood type: O Yukimura is an effeminate student who claims to be a boy, even to Kodaka's disbelief. Yukimura has deep respect and admiration for Kodaka, and even calls him "aniki" (big bro, often used with gang leaders). Yukimura wishes to learn from "aniki" how to be a stronger and more manly boy. In Volume 4 of NEXT it is revealed Yukimura is female. Due to her family really wanting a son, she was made to believe that she was a man from very young. She was even in denial that she was female upon Kodaka telling her so until Rika gave her a "lesson" much to Yukimura's shock at the actual truth.
Birthday: May 19 The wealthy blonde daughter of the school's headteacher, Sena shows a dislike of all things "ordinary." She is both attractive and academically successful, but her resulting arrogance leads her to be disliked by her female peers. Their admiration eludes her, much as she desires it; she treats her male classmates only as servants to be used, although many of them would like to be her boyfriend. Nonetheless, she holds Kodaka to a higher standard. Kodaka concludes that she is the weirdest member of the club, as she is able to warrant weird and disgusted looks not only from Yozora and Kobato, but also from Yukimura and Rika. She enjoys playing video games—including dating sims and eroge—partially because they allow her to make female (if virtual) friends. Yozora calls her "Meat" (Niku) an insulting nickname which she secretly likes because it is the first she has ever received. Her father is a friend of Kodaka's father, and pulled strings so that Kodaka could attend St. Chronica's. She really likes Kobato, since she always get really excited when she sees her. Usually, when Sena and Yozora fight, Sena usually runs from the room crying and shouting "Stupid Yozora! Go die!". It is hinted that she has feelings for Kodaka. In Volume 7 of the Light Novel, it was revealed that Kodaka and Sena are fiancés betrothed by their fathers which she fully accepts. In Volume 8, Sena proposes to Kodaka, asking him to marry her. Sena also confesses to Kodaka that she loves him. In Volume 9, Kodaka replies to Sena's confession. He loves her, but due to the circumstances within the club, he is begging her to be patient. As long the club exists, he doesn't want to go out on dates. Sena agrees and the club returns to the old status quo.
A freshman and highly capable mad scientist. She was saved by Kodaka when she fell unconscious during a disastrous lab experiment, and begs to repay his kindness with sex; she joined the Neighbor's Club just to get closer to him. As a fujoshi, she is a passionate consumer of BL d�jinshi and magazines, is comically aroused by intercourse between mecha, and is delighted when Yukimura offers to have sex with Kodaka. Although there are many adult themes in the series, she is the most sexually forward member. This was clearly highlighted in her first speaking appearance, when she described the attractions of rape to Kodaka in the middle of a stunned class. She has a habit of inserting any sexual innuendo possible in her sentences, to the point where she finds it normal to convert every innocent thought into something perverted. Rika is proud of her pervertedness, as she says that she would be a boring person if people only thought of her as a genius girl. To compound her eccentricity, she speaks in the third person. In Volume 7, it was made clear that she's surprisingly the one who knows the most about Kodaka's feelings; seeing that he was just playing ignorant to their feelings despite fully well knowing them; as well as knowing his reasoning for doing so In Volume 8, Rika agrees to be Kodaka's friend, making him the first friend she's ever got in her entire life.
Watari is L's assistant, providing logistics to the investigation team. Before the team is formed, he is the only person who has seen L, and the only one capable of contacting L directly. Like L, he represents himself with an Old English "W" on computer screens. He is also a fatherly figure to L. On the surface he is Quillsh Wammy (ã‚ルシュ・ワイミー Kirushu WaimÄ«?), a famous inventor and founder of Wammy's House, an orphanage for gifted children in Winchester, England. Watari is well trained in espionage and marksmanship. Rem kills Watari, along with L, in order to protect Misa. At the end of the manga, Roger Ruvie, the manager of Wammy House, becomes the new Watari for the third L, Near. He is voiced by Kiyoshi Kobayashi in the Japanese anime and French Tickner in the English dub (except for the film, in which Ron Halder takes over). Watari's name was originally going to be "Shadow" in reference to being L's shadow, but the editor disapproved, which led to the name "Watari", which references his role as a handler.The design team decided on Watari's design during the second chapter. Obata did not put much thought into Watari's disguise because his face did not appear, but afterwards, the rough drafts had Watari as an elderly man with a single strip of hair. Obata decided to keep him as an old man because older characters were more fun to draw than younger ones because of the "weird angles" that could be created with their wrinkles, while younger characters may be designed as "attractive, normal, or ugly." Obata likes leather coats, so he had Watari wear one.Watari is Obata's third favorite human character because he likes older characters and that because Watari "seemed to be hiding a lot of ability" and "had depth."His birthday is May 1, 1933. Watari was always counted as a father and is often seen giving L snacks.
