Fin (フィン, Fin), often nicknamed "Finny" or "Finni," is the gardener of the Knight household.
Fin is a young boy with large, grey eyes and pale skin. He has short, messy, brownish-grey hair, which he keeps in a hat.
Fin usually wears a hat, a white dress shirt, and dark beige pants, along with black knee-high boots. The reason he wears the hat around his neck is because it conceals a tattoo of "S-011," that is engraved on him from the days when he was used as an experiment for testing injections.
