Milika is a supporting character in the story of Eien no Filena. She is a Krechia woman, the wife of a battler named Ficos and the mother of a son named Fis. Her husband is killed by Filena during a gladiatorial match ordered by the empire, which fuels a deep grudge and vengeful side in Milika. Initially she distrusts Filena and attacks her by throwing a caustic substance or poison into Filena’s face, temporarily blinding her as an act of revenge. Despite this hostility, Milika is also shown to be a protective and caring person, especially toward her son. After Fis is taken hostage by the empire’s forces, Milika reluctantly joins Filena, Lila, and Nest in their escape from the town of Dora. Over the course of the journey, she moves from being an antagonist to a cooperative ally. Her protective instincts extend to her companions, and she ultimately sacrifices herself by pushing a Baraba off a cliff during a bridge chase, falling to her death. Milika’s development is marked by her transition from a grief-driven desire for vengeance to a self-sacrificial act that helps the group progress. Her notable abilities include the use of poison or acid to blind her target, and she is associated with a flute, which she leaves behind after her death.
