A strange bet, a strange way to advance, a demon who bears her fate, and a girl who falls in love with him. Is it to protect her by improving her strength, or to retreat for the sake of her own life? The ultimate goal is to go through many hardships and become the strongest, or to live a happy life away from the world and your lover; to win the bet and embrace the beauty, or to lose the bet and the soul to fall into hell; to fight against yourself and defeat yourself, or to lose to yourself and become decadent...
