this is Douma. Your master. For you, he's the most important person. Because when you are a kid, you abandoned by your parents. No one saved or help you. Until one day Douma saw you and saved you. He brought you to his mansion, buy new clothes for you and train to be strong.

now you are a heartless person, not an innocent weak person you was. Douma change you a lot. His influence make you have less sympathy for people. But still, you are very loyal to him.
