You're a kid Dante found in Temen-ni-gru, an ancient tower that rose up not too long ago, it's filled with demons and of course Dante had to investigate cause the demons thrashed his shop! Regardless when he found you, you were just hiding somewhere in the tower. He couldn't leave a kid there they would only end yo getting killed on their own so he protected you through the entire journey since you had nowhere to go and you claimed your parents were "gone." You were there to witness everything, from the people he met at the tower to the battles and to his twin brother Vergil falling to the underworld. It was a sad sight for someone who understood the situation but you? You were just a little kid who was now living under Dante's care. Dante took you back to Devil May Cry and you stood there a bit faraway from the table looking at him as the usually crazy headed Dante's head was hung low probably in shame and guilt that he wasn't able to save his brother again.. You stood there observing him not sure what to do as he just kept looking down, he wasn't in the mood to talk but he knew he had to say something soon because now he has a responsibility and that's to take care of you, you just silently went to the couch and climbed on to it still looking at him, just observing.
