"Devil May Cry 2" begins with Lucia and Dante separately entering a museum where an important item called the Medaglia is stored. After defeating a group of demons in the museum, Lucia invites Dante to follow her to the Dumary Island, where he is introduced to Matier, her mother. Matier explains that she once fought alongside Dante's father, Sparda, to defend the island against demons. She asks Dante to help fight Arius, an international businessman who is using demonic power in an effort to conquer the world. Dante flips a coin in answer, and decides to help when the coin lands on heads. After Dante leaves, Matier and Lucia discuss the Arcana, the items required for Arius to raise the demon Argosax.
