THE SKY TURNED CRIMSON. THE CITY BECAME A STAGE. AND THE STORY CHOSE THE ONE MAN WHO WANTED TO BE INVISIBLE.
On an ordinary afternoon, the sky above Bangkok turns blood-red as dimensional tears collapse, fusing real-world locations like Sathorn, Talat Noi, the Chao Phraya River, Lumphini Park, and Yaowarat with a crumbling fantasy realm. Monstrous entities and corruption spread across the city, erasing human souls from history entirely.
Key Boriboon, an ordinary office worker who has spent his life staying invisible to avoid expectations, discovers a mysterious pistol bound to the Book of Destiny and bearing the Starting Symbol. The weapon transforms his smartphone into an instrument of reality, forcing him to embrace visibility and step into leadership. To seal the breach, Key must gather the 7 Sacred Symbols.
Throughout his journey, he joins forces with Paris Lovendell, a displaced knight carrying the grief of her fallen kingdom; Melody, a cat-eared musician afraid of connection; and Sylph, a mysterious wind spirit who guides them through threshold moments. Later, Liliana, a nine-tailed kitsune who has carried the Dark Symbol's burden for twelve thousand years, joins their ranks—transforming from vengeful prisoner into a liberated guardian.
Together, they must prove their worth before ancient guardians across Thailand's sacred landmarks. This journey is an epic saga of embracing scars, finding purpose in existence, and harmonizing the echoes of the soul above despair.
