When Rukis mother, a model, shows up to school, she ends up causing quite a bit of fuss around her before suddenly leaving. When Ruki returns home, her mother notices her playing with Digimon cards and says that its nice to see her enthusiastic about something, urging her to find what she wants to do in life.
The next day, Ruki is pleased by the sight of a Digital Field and runs home quickly to change out of her school clothes, get her Digivice, and call Renamon. As Ruki leaves the house, her grandmother notes that she acts like a boy before telling her not to come back too late.
At Guilmons hideout, Takato, Guilmon, Jian, and Terriermon have a very intense game of rock-paper-scissors before Guilmon and Terriermon notice the presence of a Digimon nearby. Ruki arrives at the Digital Field to find that the emerging Digimon is an Allomon and commands Renamon to attack, adding a YukiAgumonnote s snow attack to Renamon via Card Slash. The Allomon manages to hold back the attack and slam Renamon into a pole, and Ruki expresses frustration that Renamon cant evolve.
Guilmon and Terriermon intervene in the battle, and Ruki yells at the arriving Takato and Jian not to interfere, still sticking to her belief that Digimon exist only to fight and using a power-up card on Renamon. Renamon defeats Allomon and loads his data, and the two of them take off with Ruki saying that they could have defeated him without Guilmon and Terriermons help.
From behind a pole, a mysterious Digimon watches over Guilmon and Terriermon, calling them pathetic for sticking around humans...
At home, Ruki continues to berate Renamon for not evolving, and at night Ruki thinks about the day Renamon became her partner: after overwhelmingly winning a Digimon card battle tournament, shed returned home and sat there in boredom until her card scanner had begun to glow and images of Digimon around her appeared, begging for the great Digimon Queen to become their Tamer. Ruki yelled that she only wanted a strong Digimon and one of her cards turned into a blue card, and Renamon appeared out of the masses. Ruki slashed the blue card through her scanner, turning it into a Digivice, and Renamon declared herself the strong Digimon that Ruki wanted.
Back in the present time, Renamon wanders around, saying that she will definitely evolve for Ruki and that shell defeat and load the data of many more Digimon so that she can. She runs into the Digimon who had spied on Guilmon and Terriermon earlier, who tells her that hanging out with Ruki means that she cant do anything on her own.
Rukis Digivice glows and Ruki calls for Renamon, but Renamon doesnt arrive. Rukis Digivice analyzes the Digimon as Impmon, and meanwhile Impmon declares to Renamon that hes capable of doing things without being ordered around by humans. Impmon tries to convince Renamon that she should live like him, saying that Digimon who live with humans are pathetic, but Renamon shrugs him off and walks off. Impmon lands a small attack on her before taunting her and vanishing.
Another Digital Field appears, which also fails to avoid the notice of the mysterious Government Agency of Fiction. Ruki approaches the field and Renamon pulls her out of the way of a Dokugumon before going to attack him herself. Renamon becomes paralyzed and caught in Dokugumons web, and Ruki runs forward to help her despite Renamons protests for her to stay away. Ruki ends up getting caught in the web herself and finds herself mentally pleading for Renamon to save her, only to be startled when Renamon actually does so. Renamon tells Ruki to run and Ruki, unwilling to do that, uses a Card Slash to give Renamon Snimons blades to cut the web down.
Unfortunately, this doesnt prevent Dokugumon from biting harshly down on Renamons body, and Renamon manages to pull herself together in order to use her body to shield Ruki from another attack. Ruki is still shocked from seeing Renamon risk herself to protect her, and Renamon insists that Ruki run away, saying that shes protecting her because shes her partner. Culumon appears, worrying over them, and Ruki, fearing with genuine concern that Renamon could die, calls for her. This causes Rukis Digivice to light up, triggering Renamons evolution to Kyuubimonnote . Culumon looks at Kyuubimon happily while she makes short work of Dokugumon, defeating him and loading his data. Ruki is impressed with Kyuubimon, and both of them are satisfied with Renamons evolution, but Impmon, watching from afar, declares it as disgusting and departs.
Kyuubimon tells Ruki that she protected her because theyre partners and asks Ruki if she knows what that means, to which Ruki replies that she does...a little.
