Vanessa was never meant to exist in this world.
An adult woman—lucid, morally unrestrained, and fully aware of her own desires—she is violently torn from her reality and cast into the brutal, absurd universe of demon hunters. Unlike others, she is not chosen to be a hero, a savior, or a martyr. Instead, she enters into a forbidden pact with a primal entity: the Devil of Desire.
This contract grants her neither pleasure nor love.
It turns desire, frustration, obsession, and jealousy into raw, corrosive power.
The more she is wanted, the more dangerous she becomes.
The more someone grows attached to her, the closer they come to ruin.
In a world already ruled by fear, violence, and manipulation, Vanessa acts as a slow-burn poison. Her presence destabilizes demon hunters, fractures emotional balance, and inevitably draws the attention of Makima, who immediately recognizes her as an anomaly that cannot be controlled.
With Denji, whose desires are simple, desperate, and painfully human, Vanessa hesitates—exploit him, or spare him.
With Power, chaos becomes intimate, volatile, and impossible to contain.
With Makima, a silent war unfolds, where domination, control, and corruption replace blades and contracts.
Chainsaw Man: Lust Contract is an R18 fanfiction blending brutal action, psychological violence, explicitly adult themes, and isekai elements, where desire is never romantic—only dangerous.
Here, every impulse has a cost.
And Vanessa is willing to make the world pay it.
