Butsuma Senju was the leader of the Senju clan during the war-torn era preceding the era of hidden villages. A man of tall stature, he also possessed black eyes and shoulder-length black hair kept back out of his face by a piece of light green cloth tied around his forehead. He also had a prominent jawline and wore the red standard armour of that era emblazoned with the Senju symbol at the front and on both sides of the shoulder plates, accompanied with mesh armour underneath his attire. In addition, he wore a sword over his right shoulder that is occasionally accompanied by a tantō on his left shoulder guard. While in the Senju clan's keep, he is seen wearing black civilian robes similar to that worn by his clansmen.
