[DeepL Translation - needs review] Volume 1 introduces: dominoes, origami, evacuation drills, and cats ....... The variety of activities is extraordinary. The mysterious boy Seki-kun's games turn the desk into an amusement park and fascinate Yokoi-san, the serious girl sitting next to him! ...... even though it is in the middle of class. Sometimes super-development, sometimes surreal, and sometimes heartwarming closed-space comedy that develops in the limited space of a quiet classroom!

Anotehr very cute volume with lots of stories that never made it to the anime. Seki's dice game and Zombie Othello were highlights. Generally the toughest bits are the handwritten kanji and the more fevered Yokoi's reactions get the more colloquial and extreme they get, but still a fairly easy read and even if you don't get every word the images give you more than enough context.
