The plot begins with Devil May Cry 3 in Dante's as yet unnamed shop as a mysterious man named Arkham arrives with a message from Dante's brother, Vergil. An immense tower erupts from the ground a short distance away from the shop, and Dante takes it to represent a challenge from Vergil. Following numerous battles Dante arrives at the tower's summit, Temen-Ni-Gru, and battles Vergil. Vergil defeats Dante, apparently killing him, and departs the summit. However, the dormant devil power within Dante revives him, and he sets out in pursuit of Vergil. He eventually catches up to him in the control room located in the tower's basement. The brothers battle again until they are interrupted by Lady, then Arkham, who reveals that he has been manipulating all three of them to reactivate the tower. He intends to steal the Force Edge, Sparda's sword, and reopen the gates to the demon world, over which he will rule. Arkham leaves Dante, Vergil and Lady for dead and heads into the demon world. However, Dante follows him, eventually catching up with him, where he and Vergil work together to defeat him. Dante and Vergil then fight one last time, with Dante proving victorious. At this point, Vergil then dives deeper into the demon world. Returning to the human world, Dante meets Lady outside the tower where she coins the phrase "devil may cry" while trying to comfort Dante over the loss of his brother. They form a friendship and the beginnings of a partnership in demon-slaying, and he names his shop "Devil May Cry".
