Earl Ciel Phantomhive is the main character of the Kuroshitsuji series. 

He is the current head of the Phantomhive family, the notorious Queen's Watchdog,
and the owner of the Funtom Company.

Ciel nearly always wears a black eyepatch with a single cord over his right eye to hide
the location of his Faustian Contract with Sebastian Michaelis.

'Smile' is the alias that Ciel uses on the 3rd series of Kuroshitsuji(Black butler).
You can complete the 'Smile' look using face mark stickers.
