She tells him about her doubts and then asks him to kill her again. Watching this seemingly end, Lucia attacks Dante and asks him to kill her. Dante attacks the distracted Arius and defeats him. After something in it goes wrong, it is revealed that Dante had switched the Medaglia coin with his own. Lucia and Dante manage to enter the Uroboros Corporation's skyscraper building again, just to see that the sun has completely eclipsed and that the ritual cannot be stopped. Then after Lucia thanked her mother for the truth and love, she goes after Dante. There she also meets with Matier, who confirms that they are not tied by blood, but also says that their ties are bound by history and experience, which are much deeper then blood. Lucia then asks him why he saved her to which he replies that 'every hero has a weakness'. However, Dante transforms into a devil and they fly to safety. After Arius and Dante fight, the sorcerer uses his hostage to pull them both out of the building.

Later Dante comes to rescue her, and gives out all the Arcanas despite Lucia's protests. After that, she leaves to finish Arius by herself, but is unsuccessful and gets captured. When she gathers them all, she gives Arcana to Dante, asking him to bring them to Matier for her. After she angrily rejects, he says that 'the world is already warped' and that 'everything that belongs to the devils will eventually revert to its original form', including Lucia, and leaves her, uncertain about her own future.Дespite this, Lucia continues her mission to find all the remaining parts of the Arcanas. Then he demands that Lucia gives him the Arcanas that she have already found. He also tells her that a mark on her left shoulder - 'X' (Chi, pronounced 'Kai') - is actually her real name. He says that she was a 'defect' and so was about to be disposed of when Matier found her. Much later, Lucia meets Arius who reveals to her that she is actually a mannequin, like the Secretaries, and was created by him. Dante accepts, and he and Lucia start their quests separately. Matier asks Dante to help Lucia to find the remaining parts of the Arcanas, the four ancient, sacred relics used to seal Argosax away from this world and the artifacts which Arius is so desires for. Lucia lures Dante to her island so that Matier, her mother, may ask him to help them to defeat Arius, a sorcerer and millionaire who has turned their land into a paradise for demons. Like Dante she has also a Devil Trigger form, resembling a bird. The most notable pieces of her wardrobe are her short, white cape and her exposed midriff. She wears her bright red hair in a braid over her left shoulder. Lucia is tall and lithe, and has dark skin. 2.2 Devil May Cry 5 -Before the Nightmare.
