During science class, Seki's attempts at constructing a hanko stamp from his eraser are hindered by his laid-back classmate, Akiyasu Uzawa.

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.
