Yokoi-san is trying her best to listen in class, but she can't help but watch as Seki-kun is lining up erasers next to her. Seki-kun! Are those dominoes?!

Yokoi-san is trying to pay attention as usual. And then Seki-kun starts playing shogi next to her and it turns into something rather unexpected.

Whilst participating in a disaster drill, Rumi notices that a robot family that Seki has brought into class is taking the drill more seriously than Seki himself, prompting her to take responsibility for them.

Seki crafts another shogi tale, this time depicting a princess who marries a pawn but is soon kidnapped.

As Seki knits in class, Rumi watches him as an expert, but is surprised by some of his maneuvers as well as the final product.

Seki studies a set of driving rules, takes a written driving test, and then makes a driving course on his desk for a remote-controlled car, which he takes very seriously.

As the class watches an instructional video, Seki plays a game of "Shogi vs. Chess" in the dark, with Rumi eager to help the shogi pieces as they struggle against the black chess pieces hidden in the darkness.

Seki puts on a blindfold and plays a game of fukuwarai, which soon evolves into a twisting story about family life.

Seki brings various pairs of glasses to see which pair looks the best on him.

Seki draws a flip book comic in his textbook, which he even records sound effects to, leaving Rumi curious about the finished result.
