In the hidden archipelago of Anfassia, scent is more than just an identity; it's power.

Each citizen is born with a unique scent that represents their soul. Emotions are bottled, traded as currency, and worn as social status. The scentless are outcasts. The scentless are forgotten. But behind this fragrant society lies a terrifying secret: the royal press transforms humans into immortal perfumes.

Syrene, a girl born without scent but cursed with the ability to sniff out lies, unravels the perfume facade after stealing the queen's most powerful essence—the scent of justice. As justice fades from the island, Sirene discovers that her stolen scent, the scent of first rain, is the secret to the queen's immortality... and that her missing mother has been bottled and displayed in a perfume dealer's private collection.

Led by Victor, a mysterious merchant who claims to have been a perfume, and haunted by the prophecies of a man with a glass nose who can smell the future, Siren lands in the Market of Memories, where identities are auctioned and perfumes are worn by ghosts.

At the heart of the island lies the Great Distillery, a monstrous device capable of preserving beauty forever, at the sacrifice of humanity. Siren must choose between becoming a perfume to save humanity...or destroying the machine and unleashing emotional chaos on the world.

In a final act of defiance, she drinks her bottled memories—only to discover a truth even more surreal than the prophecy: Victor is her son from the future, sent back to stop her fate.

As the island begins to smell new, previously unknown scents, Siren finally realizes the power she possesses—a scent not for sale or for confinement... but to awaken a world dormant in memory.

"The day I found my true scent, I understood why they feared it... It smelled like the world before it was created."
