In a twin-city world where glamor and filth intertwine, Tobias, a down-and-out painter under the bridge in Piltover, used his last coin to exchange for a tube of strange "living paint" from the Zaun black market. This pigment is like a living poison that can sense and swallow strong emotions, giving the painting a short and distorted life, and even tearing apart the curtain of reality. When the sad girl in his novel came to life on a rainy night, and her tears turned into real showers, Tobias became famous overnight, but he also attracted hunting in the shadows and scrutiny under police badges. He was immersed in the ecstasy of artistic realization, but was horrified to discover that every time he put pen to paper was sucking his life force, and every painting sold was quietly eroding the collector's mind. On the precipice of art and madness, when an out-of-control "emotional antidote" painting tears apart reality and releases an all-devouring demon, Tobias is forced to make the ultimate choice - using his own flesh and soul as the final paint, sealing the demon into the eternal cage of a self-portrait. In the end, he embraced this soul-eating work and jumped into the bottomless abyss of Zuan, becoming the cruelest swan song and sacrifice of art. This is a dark fable about creation and destruction, desire and redemption, etched with blood-stained exclamation marks in the eternal neon lights and gloomy light of the ditches in the Twin Cities.
