As Black Heart, she slightly amplifies most of her original traits. She becomes more aggressive, competitive, confident and way stubborn than ever. She is always ready for a challenge or a battle. Other than that, she's basically the same. Noire is the human version of Black Heart and has the ability to transform into her NEXT Form like the other goddesses. Noire, in a word, is tsundere. She is a girl who thinks highly of herself and strives to be number one in everything she does.
