Seki-kun starts shining his desk during class. Amazed at the effect of his work, Yokoi-san finds herself being dragged into his want to shine more desks.

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 creates an elaborate post office system for passing notes around the class; with many protocols that prevent Rumi from giving him a note of her own.

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.

Rumi watches in harrowing anticipation as Seki has a group of miniature bears do a mountain climbing expedition on the back of their classmate, Takahiro Maeda.

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