Hornet Sonia

Sonia was the daughter of Ludwig with his first wife. As Ludwig was not a god at the time of his birth, Sonia is not a semi-goddess. Sonia to his half-brother, Eden, born, sworn to protect, and so followed the Mars plan and Medea, which was to become the new king Eden on Earth.

So, Sonia became a Mars Army member (wearing the Hornet Galaxy), and Medea, as the first mission, he killed Kasuma, who was father of the future Lionet Saint (Souma). Sonia has just fulfilling its mission, very hurt inside, hating the act did; but it was all for Eden. Gradually, Sonia was getting colder and merciless of killing.

Souma tried to avenge his father, but Sonia manages to escape alive. His brother betray Mars, Medea tells Sonia wear Scorpio Cloth and try to convince Eden to return to ally the father. Souma but get there earlier, and asks Sonia to live their own life, without having to take responsibility for anyone. Sonia mocks the Souma face, and uses its most powerful technique, however, this ends up leaving her for dead, clueless space where it is; Souma trusts in Sonia and regrets his death, which occurs shortly after.

Mars and Eden lament Sonia's death, but Medea simply feels nothing for her death, as the battle treated as object, as it did with Mars and love.
