Volume 1

 * Dante is attacked in his office by a mysterious woman named Trish. He impresses her by easily brushing off her assault, and explains that for years, he has hunted demons in pursuit of the ones who killed his mother and brother.
 * Trish explains that her attack was a test, and that the demon emperor Mundus, whom Dante holds responsible for the deaths of his family, is planning to cross over into the human world after centuries of imprisonment. They arrive at an immense castle on the mysterious Mallet Island, where Mundus has steadily grown his power and influence over the years in preparation for his ascension. Trish quickly abandons Dante, who is forced to continue on his own.
 * Dante explores the castle, fighting off demons summoned by Mundus to attack him and overcoming all sorts of devious puzzles, traps, and tricks. He also obtains two magical weapons, a sword called Alastor and a pair of gauntlets known as Ifrit, and encounters the first of Mundus' servants, a giant spider/scorpion demon known as Phantom. Dante wins their battle, but Phantom escapes and swears revenge before Dante eventually impales and kills him.
 * Dante goes on to defeat the other servants: a giant demon bird known as Griffon, a living bioweapon referred to as Nightmare, and a masked "dark knight" known as Nelo Angelo who impresses Dante with his confidence.
 * In their first battle, Dante manages to defeat Nelo Angelo and is about to deliver the final blow when his opponent suddenly overpowers him. Nelo Angelo prepares to kill Dante, but hesitates and then flees upon seeing the half-amulet Dante wears, which contains a picture of his mother. After two more encounters, his true identity is revealed as Dante's identical twin brother, Vergil, brainwashed by Mundus and made one of his minions. After Vergil seemingly dies, his amulet joins with his brother's half, and "Force Edge", Dante's primary sword which he inherited from his father, changes into its true form and becomes the Sparda sword.
 * When Dante tries to save Trish from Nightmare, she betrays him and reveals that she is a spy for Mundus, but when her life is endangered, Dante chooses to save her. Claiming he did so only because of her resemblance to his mother, he warns her to stay away. Yet when he finally confronts Mundus, who is about to kill Trish, Dante again chooses to save her and is injured. Mundus fires a beam to kill him, but Trish takes the attack instead. This unleashes Dante's full power, thus allowing him to take on the form of Sparda. Dante and Mundus then battle on another plane of existence.
 * Despite Mundus' overwhelming power, Dante is victorious, and, believing her to be dead, leaves his amulet and sword with Trish's body before departing.
 * Returning to the island, Dante finds that the castle is collapsing, and is cornered by the injured Mundus, having used the last of his power to cross over into the human world.
 * Dante fights Mundus, but is unable to defeat him until Trish suddenly appears and infuses Dante's guns with her magic.
 * Dante banishes Mundus back to the demon world, and the emperor vows to one day return and finish his conquest.
 * When Trish tries to apologize, she begins to cry, and Dante tells her it means she has become human and not just a devil, because "devils never cry".
 * Dante and Trish escape on an old biplane as the island falls into the sea.
 * Dante and Trish now work together as partners and have renamed Dante's business "Devil Never Cry".

Volume 2

 * Lucia and Dante separately enter 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.
 * Lucia eventually confronts Arius, who reveals that she was his creation. When she moves to strike him, he uses his magic to blast her away. Shortly afterward, Dante meets up with Lucia, who gives him the last of the Arcana before leaving.
 * Dante then encounters Matier and tries to pass the Arcana to her. Matier, in turn, asks Dante to take the Arcana to save Lucia, who has gone to fight Arius again. Dante flips the coin again to decide if he will help; it lands on heads, and he departs to aid Lucia.
 * Meanwhile, Lucia enters the Uroboros tower and attacks Arius, who captures her. Dante arrives and trades the Arcana for Lucia, then attacks Arius. To escape, Arius forces Dante to decide between saving Lucia or killing him.
 * Lucia, worried about the ritual and conflicted about herself, wonders how they will stop Arius. Dante waves her off, stating he will find a way.
 * Dante leaves Lucia to think as he departs to defeat Arius.
 * Matier arrives a short time later, sets Lucia's mind at ease, and persuades her to rejoin the fight against Arius.
 * Dante arrives at the tower to find Arius in the middle of his immortality-inducing ritual. However, Dante is not worried as he switched one of the Arcana with a false coin. Another fight ensues, in which Dante finishes Arius off with his pistols.
 * Outside, Lucia confronts Dante and demands that he kill her because she fears she will become a demon herself. Before the issue can be resolved, a large stream of energy strikes the tower and a portal to the demon world is opened.
 * Dante and Lucia argue over who will enter and close it from the inside; Dante offers to leave the issue up to fate. He flips the coin and it once again lands on heads, leaving Dante to enter the portal to deal with the partially summoned Argosax, after leaving the coin with Lucia.
 * After Dante departs, Arius returns to life bearing demonic power.
 * While Lucia fights Arius, he finds himself injured and attempts to distract her, a tactic which fails, and Lucia goes on to defeat him.
 * Within the portal, Dante fights and defeats Argosax. Finding the portal closed behind him, Dante instead drives further into the demon realm on a motorcycle.
 * In the aftermath of the battle, Matier attempts to reassure Lucia about Dante's fate, insisting that Sparda returned from a similar trip. Lucia examines the coin Dante left with her and discovers that both sides are identical.
 * Sometime later, in Dante's shop, Lucia muses about Dante. Outside the sound of a motorcycle echoes, and Lucia leaves to investigate.
