Contracted Light: Guarding the Withered World Tree

In the shadow of the predetermined end, how a group of selected teenagers shoulder their fate, find hope in despair, and complete self-growth and redemption through protection; The World Tree gave birth to the four elements and the laws of the universe, and later gave birth to the black dragon Nidhogg of Destruction. In ancient times, Covenants were active and were the patron saints of various civilizations. However, as time goes by, due to the withering of the World Tree and the continuous decline of the energy of heaven and earth (spiritual energy and magic power), the traces of gods and Buddhas gradually become legends, and the covenanters go underground, forming a secret "Night Watch" organization. The story takes place in a seemingly ordinary modern city. The Contractors pretend to live as ordinary people, but they all know very well: as the World Tree dies, their power is weakening and their lifespan is shortened. This is a "withering era" with no future. .
