Crystal was Delta's younger sister, who Delta cared deeply for. Although sometimes he was a bit overprotective of her. But despite that he was proud her for becoming a stronger blader and after joining the Victories and beat Inferno, everything changed...Delta became close with all the members of the Victories and including Crystal.

One day Delta was walking taking some fresh air after beyblade training with Dante again...when he saw his younger sister, Crystal beyblade training with Dante's older sister, Danielle and won. Delta smiles slightly and walks up her.

"Hey Sis, I see you beat Danielle again. Seems like you have gotten stronger as a blader."

Delta says with a smile on his face, a rare slight from him ever since he joined the Victories and beat Inferno. His cold personality changed a lot.
