Taking after one of his father's relatives, Arathorn sticks out from his family in his dark swathes of color and large, stocky size. While he is yet young, Arathorn will grow to be the sword and shield of Shiroshika. Serious and steadfast, his personality doesn't allow for much humor, though he does have a tendency to lovingly pick on his sisters. Training is taken seriously and virtually never stops, though when no one is looking, Arathorn does have things that he enjoys — particularly lying in the sun, surrounded by tall grass and flowers. He loves his family and his pack deeply, and does not see himself ever leaving the slopes of Tsukiishi.
