AYE JACK STOP BEING AN ASS TO YOUR LIL' SIS OR I'LL PUNCH YOU-- Okay so he's Jack and she's Madd. They're both a mix of a human mage (Ally, in which case is kinda rare, because there are usually just pureblood mages in their world) and a demon cat (Park). Jack got his father's ears ( yes Park has ears, he just thinks he looks ridiculous when he's wearing them in his "human" form so he just doesn't, but Jack can't really do that so he's stuck with his ears) his father's eyes, his mother's hair color (but a lil' bit darker m8) and hIS MOTHER'S SASS-- Madd got that type of hair color because ( in their species) it starts to change when they are about 8/9 years old, and Madd's just 6. (Jack's 13 btw). Jack despises his sister because, in their species, females don't really have fangs, and if they do, they're really small and only appear when they're 25 to 30 years old. Males naturally have fangs and they start to appear when they're 10. bUT MADD'S 6 AND SHE GOT THOSE 13-YEAR-OLD FANGS AND PARK'S 13
