Lonely Sea

[Plot Direction] + [No Emotional Line] + [Single Female Protagonist] Demons are born with the ability to use magic without any external force. They are a race created by the God of Magic. Before the war against demons began, they received preferential treatment in various fields. Later, the war against demons ended with the defeat of the God of Magic, and the gods also disappeared after the war. At this point, humans have become the absolute masters of this land. Except for the legacy of that war. Dark Forest is one of them. Something unknown caused great pollution, creating several areas that were eroded by powerful magic like dark forests. Disasters and diseases will overflow from it. These powerful magic powers are considered to be the fragments left behind after the death of the God of Magic, so the demons are also considered to be the spreaders of disasters. As if to confirm this conjecture, after the war, all demons over the age of thirty died mysteriously, and the rest will also die on the night of their thirtieth birthday. At this point, the demon clan that once had supreme glory became a short-lived and tragic race.
