By the author of "Working!!," this 4-koma features the staff of the health and welfare section of the ward office of a certain city. Newcomers Hasebe Yutaka, Yamagami, Miyoshi Saya, and their supervisor Ichimiya Taishi go through the everyday quirks of working at their office.

Kentarou's former shogi teacher taught him to (metaphorically) dive into the 81 squares of the shogi board. Thus, his nickname is "81 Diver". He has failed to enter the professional league of shogi competition. However, he continues to play the game for a living by gambling at amateur shogi clubs.

One day, a strange transfer student appears before Tsubaki. Urabe Mikoto is an antisocial girl, whose hobby is just sleeping during class-breaks. One day, Tsubaki goes to wake her up and accidentally tastes her drool... and gets hooked on that!

After that, he starts going out with her and gets to know her better. Her second hobby, as it turns out, is carrying around scissors in her panties and cutting paper into flowers...
