Milka appears in episode six under the care of Seiren. She is a girl with a cruel past who is trapped in her five-year-old body. Milka lives on an island, and has no one to befriend but Seiren and her white tiger, Rascaless. Her initial caretaker was an older woman who used to whip the child as a punishment for such trivial offences. Eventually, the old woman is killed by Rascaless when Milka isn't watching. Initially afraid of Hazuki and Lilith, she warms up to them and has Seiren take them to the villa at the center of the island. In the game, Milka is sent to live on the island by her older brother, for whom she has romantic feelings, because of her poor health. Seiren sings on the cliffs everyday to keep all of Milka's brother's soldiers under her spell, and Milka on the island. After Seiren and Lilith's reconciliation, Milka goes back to her brother with Rascaless.
