Ha Yuri Jahad, more commonly known as Yu​ri Jahad (lacking her family name "Ha"), is a High Ranker and Princess from the Ha Family. She is also the owner of Black March and Green April, two of the 13 Month Series. She is the first Princess to own two 13 Months at the same time since Garam Jahad. Notably, she is one of the most famed Princesses, and perhaps one of the most favored.
