An angel's grace is a powerful entity that allows angels to possess celestial powers. Without it's grace, a angel is just as weak and fragile as a human. In rare occasions, an angels grace has the ability to turn into other living things such as flowers and trees. Although one case which has never been recorded is when a angels grace turns into a person.
