Instead of doing normal activities that other girls would participate after graduation, these girls decide to participate in Vale City's belly fighting tournament. Their goal is to become the best belly fighters by going through the 14 ranks, defeating the three nobles and the city mayor, Charlotte the Belly Queen within a 31 day period. During all this time, the three slim graduates will need to train, fight other girls and gorge themselves to become the best and most bloated belly fighters around. They will also meet a large cast of characters, who'll give them quests, challenges and various useful rewards.
