Blue Veins: Apothecary Reign

A Dark Fantasy / Alchemic Tragedy The genome was never meant to be a prison. It was meant to be a weapon. Renji Valenhart’s life is built on a fragile routine: survive high school, help at his grandmother’s pharmacy, and hide the strange blue glow that sometimes glows beneath his skin. His only anomalies are the chemical equations that write themselves in his mind and the unshakable feeling that a piece of him is missing—a feeling that sharpens into physical pain with each passing day. When a school lab accident triggers a public display of his power, Renji’s careful normalcy shatters. In the aftermath, he’s haunted by violent psychic flashes of a silver-haired girl trapped in a laboratory prison, a girl who shares his face and his forgotten past—his sister. He learns the truth: he and Reika were their mother’s final biopunk experiment, created to rewrite human chemistry itself. While Renji’s memories were sealed, Reika was taken and reshaped into a living weapon by Kagura Yurei. Now, the sentient, chemical-knowing book called the Helix has bonded to Renji, calling him “Catalyst Strain Iota.” And Kagura wants to complete her set. To salvage the last fragments of his ordinary life and save the sister he can’t remember, Renji must master the volatile science in his own blood and decode the living memories in the Helix. But as his power grows, so does the risk—the more he remembers, the closer Kagura’s weapon gets to finding him, and the more his own humanity threatens to dissolve into the cold logic of the code written in his veins.
