Spectres

あらすじ

In a world governed by the laws of heaven, an unconventional species known as Spectres plays a hidden role in historical events. These Spectres are concealers who have inherited ancient skills, constantly adapting their methods. Nine Spectres once discovered the legendary ancient Utopia land, believed to grant immortality to its inhabitants. Within Utopia, they found records of an undying divine tree. However, upon entering a mysterious mountain, only one of the nine Spectres remained, transformed into a humanoid being that is neither human nor Spectre, while the others vanished.
