Lux is a moonlight dragon slayer. After Lunesa (her dragon) left (the year 777 the same as the other dragons), Lux was adopted by a rich family. Unfortunately they made her into a little princess, when all she wanted to be free and find Lunesa. Her "parents" hate magic so they filled the whole mansion with anti-magic-lacramas. So she has no way to escape. What will happen when things change.
