|“||Look, I'm not a slave. Rika happens to be my partner.||„|
Rika Nonaka is the child of a single mother, who often spends her time alone at her house with her mother at work. With nothing else to do, Rika poured all of her time into a card game called Digimon, eventually becoming one of the best players in her city. However, everything changed when, one day, real Digimon, monsters made of computer data, emerged into the real world. Several of the Digimon wanted Rika to be their partner, who'd help them get stronger, but only the strongest of them managed to actually become Rika's Digimon. Her name was Renamon, a fox Digimon that was famous in the Digital World for her strength. Rika and Renamon spent most of their free time looking for enemy Digimon emerging into the real world from the digital realm, so Renamon could kill them and absorb their data, increasing her power even more.
While Rika originally thought of the battles as just a big game, without consequences, she realized how wrong she was when Renamon got injured in a battle with a stronger Digimon. The realization that Digimon are living, sentient creatures got Rika to care for Renamon much more, and along with two other Tamers, Takato Matsuki and Henry Wong, the bond between the two would grow even more as they protected their city from the emerging Digimon.
- Diamond Storm: Renamon fires a barrage of glowing sharpened leaves at her opponent, which explode upon impact. This attack has enough power to blast through ice and take out Champion-level Digimon.
- Power Paw: Renamon covers her paws in ghostly blue flames, boosting her attack power.
- Digivolution: By channeling Rika's emotional energy into data, Renamon gains the ability to digivolve into bigger and stronger forms. Each time she digivolves, Renamon is restored to full health and vitality.
- D-Power: Rika's digivice, which was created by swiping a strange Blue Card through her card reader, that signifies her as Renamon's Tamer. It is what lets Renamon digivolve. Due to being made from Rika's card reader, Rika can swipe Digi-Modify cards through it to power Renamon up, give her new weapons, or let her use the attacks of other Digimon.
Kyubimon: Renamon's Champion form. Kyubimon is a quadrupedal fox creature with nine tails, each one with a fireball on the tip, and flames coming from each of her feet.
- Fox Tail Inferno: Kyubimon shoots the fireballs on her tails at an opponent, burning them and engulfing them with blue flames.
- Dragon Wheel: Kyubimon spins very fast, surrounding her with blue flames, before forming the flames into a dragon and firing it at the opponent. This attack can defeat most Champion-level Digimon with ease, and even damage the Mega-level Beelzemon.
Taomon: Renamon's Ultimate form. Taomon fights with the magical energy of the universe, which she channels through several talismans, spells, and her main weapon, a giant calligraphy brush that can be used as a melee weapon, or a deadly spell-casting tool.
- Talisman of Light: Taomon paints a special symbol in the air with her brush, which releases a beam of pure light energy. The blast from this attack can one-shot most Ultimate-level Digimon, and dispel darkness surrounding her, or her allies.
- Thousand Spells: Taomon fires a barrage of red spell papers from her sleeves, which can constrict opponents or explode upon impact.
- Talisman Star: Taomon conjures a razor-sharp symbol of magical energy before throwing it like a boomerang. When it hits something, the symbol glows and magically tears it apart.
- Talisman Spell: Taomon uses a magical red spell paper to form a special construct. These constructs range from floating platforms, small bursts of energy for offense, and a nearly-impenetrable barrier that can block attacks from a Digimon Sovereign.
Sakuyamon: Renamon's Mega form, which she achieves by merging with Rika. Sakuyamon wields the Kongou Shakujo in battle, a staff usually used in prayer, and she has four spirits called kuda-gitsune carried on her waist, which she can release to attack opponents.
- Spirit Strike: Sakuyamon releases her kuda-gitsune to attack her opponent. This attack is capable of destroying the D-Reaper's weaker agents in one shot, and even severely burning one of its bigger agents.
- Amethyst Mandala: Sakuyamon strikes the ground with her staff, unleashing a purifying barrier that exorcises evil spirits.
- Twin Blades of Beauty and Truth: Sakuyamon surrounds herself with two rings of pink energy, projecting a barrier of cherry blossoms for defense.
