Petan

Flat Chest Tribe's Breast Deity

The whole reason for the war is due to a fight between Boweene and Petan over Boweene eating Petan's pudding, while Petan ate Boweene's cake. After Boweene and Petan made up, they went to slept for a thousand years due to how much energy they used, but the war still continues between the big boob tribes and small boob tribes. Only Haruto, Milphalia, and Iris know the truth and so they sent Haruto and Milphalia to stop the war. They made Milphalia Haruto's "personal boob".
