Ruki is the type of person who, in the beginning, sees Digimon as nothing more than mere computer data. She aspires for her partner, Renamon, to become the strongest Digimon ever. Eventually, she realizes that the two must be on equal partnership and friendship. She is a bit bitter and slightly antisocial thanks to her parents' divorce, but Takato and Jenrya manage to bring out the best in her.
