Ruki Makino

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, Jenrya and Renamon, manage to bring out the best in her, by showing her (among other things) that friendship is priceless.

Ruki's relationship with Renamon is unusual (due to Renamon being the most mature of rookie Digimon), they talk as equal than either a pet or a playful child. Ruki's proud, independent, grouchy and cynical personality is substantially different from most of the female characters in the series, pretty much a typical teenage rebel.
