|“||I'm not going to scold you for your lies. Rather if anyone should accuse you of lying... I would never forgive them. If anything, I want to applaud you... for doing your best all by yourself these past three years. You don't have to lie anymore. Because, you see... I've come back.||„|
|~ True Ciel to his brother|
Ciel Phantomhive's Twin is the elder twin brother of the current Ciel. He is the main antagonist in the Blue Cult arc of Black Butler and potentially one of the main antagonists of the Black Butler series alongside the Undertaker. The True Ciel is the true head of the Phantomhive house and Elizabeth Midford's original fiancé.
Ciel and his brother were born to Vincent and Rachel Phantomhive on December 14, 1875, being a few minutes older than his brother. They were close despite their differences in personality and his younger brother's asthma.
As the heir to the Phantomhive family, he was trained by his aunt Franchise into fencing. He and his brother were kidnapped by a cult and the elder Ciel was sacrificed to summon Sebastian. The younger brother named himself Ciel and decided to burn the place and corpses so no one would know that Ciel's brother would impersonate him however Undertaker managed to save his corpse and sometime later would eventually revive him.
In the Blue Cult arc, the true Ciel returned and the current Ciel and Sebastion were shocked to see him alive again. Although the servants have their doubts Sebastion eventually confirmed that the other Ciel was indeed the true Ciel and that the Ciel they have been following was his twin brother. Tanaka knew and was planning on taking it to the grave but now would be pointless. The real Ciel was not angry at his brother for lying to everyone and tells him that he no longer needs to since he is back.
- His presence had confirmed the well-known "Two Ciels" theory. The said theory was formed because of the presence of an extra Phantomhive tombstone (besides the tombstones of Ciel and his parents) shown in Elizabeth's flashbacks, which occurred during the Luxury Liner arc and its anime film adaptation, Black Butler: Book of Atlantic.
- In addition to that, in the said flashback, Elizabeth also described Ciel as a person who often smiles until the fire occurred. It contrasts the protagonist who seldom smiles. Although, Elizabeth believed he was traumatized and tried to keep his smile by pretending to be childish. However, after True Ciel's presence, this description suggested otherwise.
- It's widely speculated that the true Ciel is the murderer of Agni.
