At this time, there is a huge tower in the sky. The tower is divided into three realms: God/Demon/Underworld.
But fate is still moving invisibly.
The son of the great devil! He who inherits the name of Lucifer! A college life with lots of fun and fun but hidden dangers; a castle in the North District full of ice; a dazzling and sacred bird cage in the divine world; when the war breaks out, the wings are pulled off, and the fall into the endless abyss is the end?
Intention: The love of a lifetime, as things change, will eventually dissipate into the abyss.
