Long ago a demon by the name of Sparda betrayed his fellow demons and assisted in sealing away the demon world. Centuries later he meets a huntress by the name of Eva. The 2 fall in love and bear twins, Dante and Y/n. 17 years later, the twins join Beacon where they meet each other for the first time since they were 8. This allows them to rekindle their bond and gets Y/n to break out of his shell, leading him to forging bonds that he would usually avoid.
