Dante is the main protagonist of the Devil May Cry series. He is the second son of the demon Sparda and the human Eva, and the younger twin brother of Vergil. As such, he is a half-demon, half-human hybrid. Dante is a mercenary dedicated to exterminating demons; a mission he follows in pursuit of those that killed his mother and corrupted his brother.
Sometime before their eighth birthday, Eva gave Dante and Vergil each a half of the Perfect Amulet.
Eventually, Sparda died, and Eva and the twins were left alone. When Dante was eight years old, he and his family were attacked by demons. Devil May Cry 3 Eva was killed, and though both Vergil and Dante survived, the twins were separated, and Dante believed Vergil to have died.
At some point after this, Dante met Enzo and began a demon-hunting business under the alias Anthony "Tony" Redgrave.
A younger, cockier Dante is sitting in his yet-to-be-named shop. Arkham comes to the shop and gives Dante an "invitation" to the Temen-ni-gru on behalf of his brother Vergil; as soon as he leaves, Dante is attacked by a swarm of Hell Prides, Lusts and a Hell Vanguard. Dante effortlessly kills them all, and heads to the tower in search of an "interesting time". Meanwhile, Vergil speaks to Arkham about his plan to reopen the portal to the demon world and obtain his father's power, in the form of the Force Edge sword that lies there. Within the tower, Dante encounters and defeats the demonic gatekeepers who were sealed away by his father, as well as the demon hunter Lady, who is in pursuit of her father Arkham, and the demon Jester, who guides him through the tower for his own reasons. Upon defeating most of these demons, Dante acquires their souls in the form of new weapons and combat styles. Dante, Lady, and Vergil eventually discover that Arkham is Jester, and was using all of them in order to open the portal and acquire the Force Edge for himself, using it as a means to gain Sparda's power and become a god. After defeating Arkham in the Demon World, Vergil and Dante duel for the ownership of the Force Edge. In the end of the battle, Dante claims ownership of the Force Edge, while Vergil chooses to remain in the Netherworld.
Dante matures considerably as a result of his ordeal, and inspired by Lady's courage and commitment to her own family, he continues his demon hunting business with a greater sense of purpose. They become partners and he decides to call his shop "Devil May Cry", in reference to what Lady said to comfort him over the loss of his brother Vergil.
