Finnian, often called Finny, is a gardener. However, it seems every time he tends to the garden it is killed through an accident caused by his clumsiness. He is portrayed as an innocent, child-like character, but is dubbed an idiot by Sebastian. Finnian displays feats of superhuman strength, which he tries to suppress from fear of hurting others and risk of sabotaging his work. The sequence S-012 are tattooed to the back of his neck and are covered by his straw hat. He works as a gardener to spend as much time as possible outside because he was not able to do so before, and explains that he loves working for Ciel because he does not give him injections, kill his friends or lock him in a cage.
