Toshinari Seki, referred by his surname Seki, is one of the main characters. He is always seen playing games at his desk, from intermediate to near impossible, though he never seems to study. Seki has short black hair, green eyes, and is somewhat enigmatic. Throughout the show he is seen rarely speaking.

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!<br><br>
