Child of, Aspect of, "Annihilation".
Bet on. Any deal made with these children are set in stone. Even if their agreement is insane once "the bet is on." Nothing can stop the rewards and punishments from being brought out. Jeven and Azazel once made a bet that Jeven couldn't fit 100 donuts in his mouth. If Jeven couldn't do it then he could never eat donuts again. But if Jeven did do it Azazel would always have to follow Jeven's orders until Azazel could fit 100 donuts, whole normal sized donuts, in his mouth. Azazel lost the bet and Jeven ordered him to never fly again. Since then the closest Azazel has gotten to fitting 100 donuts in his mouth is 22. In Jeven's own words "He should have been more specific like me! All I did was fit 100 mini donuts in my mouth hehehe."
