The demon Enlil and the Archangel Lucien made a deal to prove whether humans are worthy of the souls that were given to them by God. Humans have nested and polluted the Earth and have degraded one another, they have been regarded by Enlil as worthless creatures. Lucien disagrees with this thought and said that humans are the greatest creation of God and are capable of great love and respect. Their quarrel resulted to them falling on Earth in a trance of burning light one dark night, the same night where two boys happened to drive on the road heading towards Garamound city. Their car was hit by the fallen demon and angel, due to the great impact the car was destroyed leaving the twin brothers in a life and death situation. Enlil saw the severely injured Kwangmin and agreed to let him live if he accepts Enlil, unsure of what the demon meant he agreed and soon Enlil merged with him, possessing his body and walked out from the incident. On the other side road lay Youngmin who was unconscious, Lucien saved him by making a truck driver stop by and brought him to the hospital. He soon decided to use Youngmin as well to stop Enlil. Kwangmin who is now possessed by Enlil is looking for a tainted soul in the city of Garamound, a girl named Maxim happened to have a special one and he plans to make her soul impure so he could win the deal. Youngmin and Lucien now have to do their best to make Maxim see the misleading illusions of the demon.
