The Realm of Light and Shadow

Beneath the bustle of the modern city lies an ancient realm known as the “Shadow Realm,” a place invisible to ordinary people. Only those with the “Eye of Shadow” can enter. The mysterious forces within the Shadow Realm can alter the fate of the real world, and those who control it are called “Shadow Envoys.” After an accident grants the male protagonist the Eye of Shadow, he is drawn into the conflict between the Shadow Realm and the real world. As he gradually uncovers a hidden conspiracy, he ultimately discovers his own special connection to the Shadow Realm.
