Sera's French Revolution: During Sports Day, Sera tries to overtake Sakamoto's popularity (or at least, make his popularity lower) by sabotaging the events with the cooperation of the rest of Class 1-2 boys. Despite all odds, the plan backfires on them, as Sakamoto wins the events with style, and his popularity increases as a result. In the relay race, Sera ties both of Sakamoto's shoes so that he can't run. Far from giving up, Sakamoto bites the baton with his mouth and runs like a four-legged cheetah. When he passes the baton, the baton slips from Yagi's hand due to the baton covered in saliva, which makes them fall down to last place. Seeing Yagi cries while running, Sera decides to erase Yagi's mistake from everyone's memory by doing a more memorable event... by running naked after the baton is passed to him, to everyone's gross and dismay, though Yagi thanked him later on.
