Rika Nonaka is one of the main protagonists in the anime and manga series Digimon Tamers. Her partner is Renamon.
Rika, early on, sees Digimon as nothing more than mere computer data built for fighting, wanting her partner, Renamon, to be the strongest Digimon in the world. She attempts to strengthen Renamon by battling any bio-emerging Digimon and having Renamon download their data after defeating them, but is frustrated at Renamon's lack of control over Digivolution. Eventually, she realizes that the two must be on equal partnership and friendship.
She is voiced by Melissa Fahn in English dub, who also voiced Gaz in Invader Zim and Seta Soujirou in Rurouni Kenshin.
