According to her household bio, Yuki, along with her older sister Candy, recently inherited a quaint, modest home from her dearly departed Grandma Behr. Yuki is a loner who values her time with herself and her game console. A total geek with a passion for video gaming, and talent too, even hacking into systems makes her day, despite the reputation it gives, as the most infamous hacker in Windenburg. However, despite this passion of hers, nothing makes her happier than the success of her sister in her DJ career. Candy inspires Yuki and makes her want to be a better self.
