OVA of Tonari no Seki-kun bundled with the fifth manga volume.

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>

Toshinari Seki takes goofing off to new heights. Every day, on or around his school desk, he masterfully creates his own little worlds of wonder, often hidden to most of his classmates. Unfortunately for Rumi Yokoi, his neighbor at the back of their homeroom, his many games, dioramas, and projects are often way too interesting to ignore; even when they are hurting her grades.
