He wishes to use Cardia as bait, but Lupin manages to meet up with Impey and Victor. After their defeat, they come face-to-face with another man holding two shotguns.

Noticing that they are being followed, an attempt to lose their pursuers in a deserted alleyway leads to a confrontation between them and soldiers working for Twilight.

Wishing to let Cardia see the world, the men take her out on a steam-engine to the streets of London in disguise, where Victor and Impey buy supplies and Lupin shows her around, leaving Saint at the mansion. The next day, Cardia is introduced to Saint-Germain, the aristocrat who is the owner of the mansion. As Isaac is involved in a terrorist plot along with a secret organisation known only as Twilight, many out there wish to capture her for the Horologium. It is that reason that Cardia possesses that certain poison, which she uses gloves and specially altered clothes to suppress. There, Cardia learns that her father, Isaac, was an inventor who created many amazing inventions, one of which, the Horologium, is embedded inside her and currently functions as her heart. Riding off to their mansion hideout in the forest, she is introduced to Victor Frankenstein, a genius alchemist and scientist who acts together with Impey and Lupin. Confined alone in her family mansion by her father, she is captured by the British Army but rescued by Arsène Lupin, a handsome thief, and his friend Impey Barbicane, a self-proclaimed genius engineer. Cardia Beckford, a young girl living in old London, is feared and branded as a monster due to the possession of a virulent poison in her body that melts away at anything.
