Affiliated with the East Asian United Front, terrorist Kim Kanthe collaborates with the Babel Brigade. His vengeful and bloodthirsty personality drives him to kill even teenagers, satisfying violent urges. Three years after the Distonian War, he participates in a terrorist attack in Iidabashi, targeting civilians and shooting multiple victims. During this assault, he attempts to kill Sayako Hata, civilian classmate of Asuka Ootorii. This act forces Asuka to transform into her magical girl form for the first time in three years, intervening directly. Kim expresses surprise at her sudden appearance but is swiftly defeated alongside fellow terrorists. Following capture, the National Police Agency subjects him to torture, extracting information that confirms the Babel Brigade's existence.
