Beast Form, Skill Shuffle
The power behind Kyoko’s beast change lies in her blood. Once a Jade Warden sexually matures, they start to manifest powers. These powers are fairly random but can be somewhat steered in certain directions by a person’s upbringing. Kyoko spent much time with her brother when she was young and its doubtless he had something to do with her inner desire to take on beast form. She might not have known it, as she did not know her brother could but that might have been put her on that path. It could have been as simple as a childhood dream of growing wings and flying away from the world. Her raven form possesses many skills and powers that allow her to do things her mortal form cant. Thus when she shifts to a raven, she is quite a different person.
