God Child, Cantarella Recommendations
Both are tragic shoujo manga. Though the main character of Cantarella (Cesara) grows up while the one from God Child (Cain) does not, they are both surrounded by tragic incidents, not always things they can avoid. Both were cursed by their father and their name bear a meaning. Both have someone to support them most of the way.
These two mangas are very good. They both have very beautiful and gothic designs and art. Also, in both, the main character is known as others as cursed, and they are hated by everyone in their family except their younger sister. And there is a guy who serves the main character SPOILER and later betrays them. SPOILER END. If you like stories that revolve around high status boys with a touch of supernatural, these are the mangas for you. Since I like both of them, there is a high chance that one of you will like both of them as well.
