"Ciel Phantomhive" is the true head of the Phantomhive house. He is also the identical twin brother of Ciel Phantomhive and Elizabeth Midford's original fiancé.
"Ciel" looks identical to his brother and they have been stated to be mirror twins, but unlike Ciel, he does not bear a Faustian contract mark on his right eye. Another noticeable difference is that while Ciel's bangs curl to the right, "Ciel's" bangs curl to the left.
He is an individual who exudes confidence and remains unruffled, even when accused of being an impostor.
"Ciel" has a notably more confident aura than his brother; he is usually seen smiling widely, laughing and playing with Elizabeth. He also did not suffer from debilitating asthma as his twin does.
