Rumi is the viewpoint character and narrator of Seki's games. She continuously attempts to pay attention in class but is almost always distracted by her neighbor's antics. She sometimes tries to make Seki concentrate on class by sabotaging his projects, but usually finds herself joining in on them, though Seki misunderstands these attempts. In fact, some episodes feature Rumi getting just as, if not more so, involved than Seki in his games, such as when he spends a day knitting or whenever he brings the Robot Family into school. In My Neighbour Seki-kun Junior, she marries Seki and they have a two-year-old son named Makuru.
Normally referred to by his surname, Seki is Rumi's classmate, and is a cheerful but mysterious character who is always playing games at his desk, which at times, include some elaborate setups. His activity bothers Rumi to no end, although he is almost never caught in the act by the teachers. In his desk is a complex array of objects that, if disturbed by anyone but himself, are impossible to put back together.[ch. 9] He rarely speaks, but is sometimes seen chatting with his friends. Despite his normal demeanor around his fellow students outside of the classroom, he is occasionally shown to have a dark and sadistic side. This comes through his destruction, sometimes wantonly, of his games and toys. He is also slightly superstitious, as is shown when some of his projects become so intense for Rumi that she secretly gets involved, scaring Seki out of his wits and his flippant behavior towards education. In My Neighbour Seki-kun Junior, he marries Yokoi and have Makuru as their son.
Sakurako Gotō (後藤 桜子, Gotō Sakurako) sits near Rumi and Seki during art class and becomes Rumi's friend. She assumes Seki and Rumi are lovers because of the way they interact in class. Regardless of any relationship Rumi and Seki may actually have or not have in the present or future, almost everything she assumes is entirely based on her own imagination.[ch. 22]Voiced by: Satomi Satō[2] (Japanese); Caitlynn French[3] (English). Portrayed by Rika Mayama in the live-action drama.[5]
Tomoka Hashino (橋野 友香, Hashino Tomoka) is Rumi's classmate with glasses.[2]Voiced by: Kokoro Kikuchi (Japanese); Jad Saxton[3] (English)
Akiyasu Uzawa (宇沢 明康, Uzawa Akiyasu) is a laid-back classmate who is easily bored and often gets in the way of Seki's activities.[ch. 36][2]Voiced by: Minoru Shiraishi (Japanese); Corey Hartzog[3] (English)
Takahiro Maeda (前田 高広, Maeda Takahiro) is a classmate who sits directly in front of Seki.[2] Due to his height and large build, he blocks the teachers from noticing Seki's activities.[ch. 20]Voiced by: Shigeyuki Susaki
Yū Nakama (仲間 由宇, Nakama Yū) is Rumi's classmate and friend. Voiced by: Mami Shitara (Japanese); Carolyn Medrano[3] (English)

Over 3 million copies of the manga have been sold as of July 2014.[43] The manga was one of the works nominated in the fifth Manga Taishō awards in 2012.[44]My Neighbor Seki was listed on YALSA's 2016 list of Great Graphic Novels for Teens.[45]
Rebecca Silverman of Anime News Network gave the first volume of the manga an overall grade of C+.[46] Karen Mead of Japanator liked that the anime put the detail into Seki's projects rather than the characters, and that while the show could have worked as a three- to four-minute short, that it gets stretched to eight minutes with opening and ending themes gives it a chance to build atmosphere and tension.[47] Richard Eisenbeis of Kotaku called it "the most basic, yet perhaps most entertaining, anime of the season."[48]
