Finnian is a teenage boy with large turquoise eyes and short strawberry-blond hair clipped back with five red bobby pins—two on his right and three on his left.
Finnian is a lively, excitable individual. Like the other Phantomhive servants, he is fiercely loyal to Ciel Phantomhive, whom he views as his savior,[6] and deeply respects Sebastian Michaelis.
Finnian is prone to emotional outbursts, particularly when he blunders at work[7] or witnesses something unjust.
