This is Robin De Noir from The Secret of Moonacre.

Robin de Noir is very much attracted to Maria Merryweather.

Son of Cuen de Noir, younger brother of Loveday, suspected love interest of Maria Merryweather. Has band of friends that he is seen with on various expeditions in the woods - they seem to by his 'click' or followers, as he seems to be something of a leader to them. Whether this is due to the identity of his father (the head of the family) or if they genuinely like him, is unknown. He has wandered the woods almost his whole life.
