Lavender

About
Lavender was a student of a prestigious Paris academy of Leazas. However, she ended up being abducted by the then Princess of Leazas, Lia Parapara Leazas.

The princess used her to satisfy her sadism and continuously tortured her heavily and using healing magic to prevent her from dying of the wounds. Everyday she would be used as the princess' toy in the periods of time between 9:00 to 11:00. She eventually couldn't take it anymore and commited suicide. However, a strong attachment to life led her Soul to remain and turn her into a Ghost, since it wasn't really her wish to commit suicide.

Rance eventually found her and it was her who told him about the Princess' secret "hobby", leading Rance to make a vow to stop Lia from making other girls get the same fate Lavender got.
