Tonari no Seki-kun (となりの関くん) is a Japanese manga series written and illustrated by Takuma Morishige. Originally published as a one-shot in 2010, it started serialization in the November 2010 issue of Media Factory's Comic Flapper magazine.
An anime DVD was released bundled with the limited edition of the manga's fifth volume on January 4, 2014, and a television series adaptation began airing in Japan on January 5, 2014.
"The original manga revolves around a girl named Yokoi who sits next to a boy only known as Seki-kun. During class, Seki-kun continues to not pay attention and instead creates amazing little distractions, such as a detailed golf course with the course's hole being a dent in his desk, or an entire dramatic war being played out by paper shogi pieces. Yokoi often finds herself getting reluctantly interested in his games, even though they always seem to end up getting HER in trouble with the teacher!"
