Rika had wanted Renamon to digivolve for a long time, but wasn't able to achieve it. However, when the two were attacked by a Dokugumon, Renamon protected Rika, thus taking the full blast of Dokugumon's attack. Rika, who had never accepted Renamon as a living creature before, cries out in sorrow over Renamon's sacrifice. This emotional response caused Renamon to digivolve to Kyubimon, who was now able to defeat the Spider Digimon.
