Tryona is a world separated by ideas and water. Special citizens, called “Blessed Children” protect the world from demons. Rina Castro is one such “Child,” but she is different – she travels between each country. She is an outcast in her native country and an outcast of the world on a mission of revenge. When she meets a young alchemist named Yu Jie – another outcast traveling across borders in search of a special potion, will she set aside her mission to help her protege, or will she accomplish her task at the risk of alienating the one person who may be able to help her?
