Anjing

-She's blind, but tries really hard to hide it. She gets around pretty well. 
-She hates shoes since she can use her feet as claws if needed. 
-Unlike the rest of her family, her clothing doesn't change between forms.
-In her bat form, she is essentially a vampire. She stops herself from eating people (unless they consent and have a one night stand or whatever) and instead hunts animals.
-Her power is very limited. She can only transform at night, and only for a short amount of time. Like everyone else, sleep forces her to change back. Also, if she drinks blood, she doesn't need to eat for a few days.
-For her, drinking blood is much more efficient, as even just a pint can hold her over for about 36hrs. When in human form, she has to eat a lot.
-She doesn't look her age. No one's really sure how old she actually is (though she's considerably young for a pseudo-vampire. At least two years younger than Heizen) No one has any idea how long she'll live. Also, she grew to about her size when she was six, and has stayed roughly the same since.
-Unlike her family, she was born with white hair and it's turned black (everyone else is the other way around). She's apparently young enough to not have completely outgrown her hair change.
-She sleeps for about two weeks straight every other year. Otherwise she takes quick hour long naps here and there, but otherwise doesn't really need to sleep.
