they used to be two different ppl. Brother and sister. there about the same age. an experiment done on them made them what they are now. Kar who is older by like 3 months. he's very aggressive and arrogant. he can be bossy and overprotective when it comes to Ma,but he loves her all the same(in more ways then one >.>)
Ma on the other hand is very mousy and quiet. she keeps to herself unless Kar says otherwise when it comes to ppl in general. Although she's not completely soft. when it comes to Kar and his advances she doesn't play.
this is Kar-Ma's first form.they have 2.
