The rules of the Big Eating Challenge are very simple. Weigh-ins are conducted before and after the challenge, and if the participant gains five kilograms or more, they win a prize of one million yen. However, if they fail, they must personally cover all food and beverage costs as well as other expenses. Since there is no time limit, the difficulty level of this challenge is extremely high. The final challenger is Mikan Tokonatsu, who normally follows a unique diet. Her strategy is to eat almost nothing for two days and attempt the big eating challenge on the third day. Mikan appears ordinary at first glance, but she's determined and persistent—though picky, once she sets her mind on something, she sees it through. For this challenge, izakaya-style dishes are prepared, and she must choose the easiest items to eat from a wide and varied menu. However, the sheer volume of food laid out on the table quickly becomes overwhelming. After the main challenge comes dessert time—Mikan devours a generous portion of cream-filled cream puffs, completing a perfect big eating challenge.
