In this chapter, we learn that there is an "elimination match" before the eating competition, which means that the competitors will have to compete against each other in order to be selected for the final round. This means that, even though Kumada was nominated, he will not be able to participate in the competition. The other competitors have been using "dirty tricks" at all the competitions they attend, and they have been able to "drive them away" until they "lost their cool" and started plotting to pretend to be "amateurs" in field matches. They tricked Kumada into signing a "contract" so that he could not compete anymore, and now they are using this opportunity to "get us" for the elimination match.
