1-D Tamura Mai-san (No club) VS 1-B Kobayashi Yuuya-kun (Gymnastics club)
At the sound of the gong, the kick should've been a one-hit certain kill, but it was a loss due to a foul.
The judge Kashiya-sensei is explaining to Tamura-san why she lost.
At the start, the girls' forces kept losing one after another because they didn't know the rule that aiming for the balls is an instant loss. Although the boys' forces are holding their crotches and fainting in agony, they happened to get in the lead this way (lol).
