Eva Sparda was a human woman and the wife of the legendary demon Sparda. She was a kind, caring, and loving mother to the twin boys Dante and Vergil. Although she was human, she was not afraid of Sparda's demonic origins and their family was united by a strong bond. She was a very important person for both Dante and Vergil, and her fate greatly influenced their lives.

Sparda was a legendary demon knight who defied the demon world and stood against its ruler to protect humanity. He was an immensely powerful, intelligent, and skilled warrior. He later lived among humans under the name Antonio Sparda and married Eva. Together they had twin sons, Dante and Vergil. His legacy and power greatly influenced both of his sons.

Dante is the son of Sparda and Eva and the younger twin brother of Vergil. He is tall, has white hair and distinctive blue eyes. He is confident, cheeky and often jokes even in dangerous situations. However, he is very brave, has a strong sense of justice and cares about the people he considers family. As a demon hunter, he primarily uses his swords and firearms and has extraordinary abilities due to his demonic origins.

Vergil is Dante's older twin brother, the son of Sparda and Eva. He has white hair and blue eyes, but unlike Dante, he appears colder, more serious, and more disciplined. He is extremely proud, intelligent, and obsessed with gaining more power. His main weapon is the Yamato katana, with which he can perform incredibly fast and accurate attacks. Although he often opposes Dante, their relationship is much more complex than simple hostility.
