When Bell and Urd left Yggdrasil for earth she was left all alone and when Urd caused an error in the system Sculd was left to stop all of the bugs(beeing that she is the one incharge of keeping bugs out of the system). Missing her Onee sama soo much she just had to go down to earth to get her back. Unfortunately for Sculd she had no knowledge of her contract with Keiichi, therefore throughout the OVA and part of the manga she doesn't like Keiichi at all and will do anything to get her big sister Belldandy back.
Sculd is very young so she isn't very skilled with magic, but she makes up for that with her mind. She invents things to help her in any way and one of her main hobbies is reading Manga ^-^
