I was pass away the world until I was 5 years old and I was taken in by ,my father the ‘Monster Duke’. One day, I sneaked into father’s study without anybody knowing and discovered a strange book… What’s up with the content? I will die because of a sickness? Then, are you treating your foster daughter well? In the end, I’ll die because I’m sick but it won’t happen before that! Then… I will do whatever I want!
