Summary
Three centuries ago, Lailah, the mother of Emilia, encountered and saved a young Satan from near-death after his tribe was decimated by a rogue demon. As she nursed him back to full health, she imparted a wealth of knowledge to him. Prior to her departure, she gifted him a purple, crescent-shaped crystal. Leveraging the wisdom Lailah had shared, Satan eventually ascended to become the Demon Lord, gathering an army of demons and gradually uniting the demon race into a single empire. He planted the crystal in his castle’s garden, where it blossomed into a tree. Throughout these centuries, Satan remained unaware that the object was a Yesod fragment.
