Butsuma Senju

was the leader of the Senju clan during the war-torn era preceding the the era of hidden villages.

Background
Standing alongside his three sons as the latest war casualties were buried, he scolded his youngest son Itama for crying as shinobi are not supposed to cry. When his oldest son Hashirama confronted him about sending a child like Kawarama to fight, the man resorted to beating his son while stating that Kawarama died as a true shinobi. With his son questioning whether or not it was death that made a shinobi worthy and if they weren't simply perpetrating an endless cycle, he told Hashirama anyone with a weapon is an enemy. At his limit with Hashirama, he prepared to strike his son again before his other son Tobirama intervened and explained that Hashirama was just grieving. Having calmed down himself, he told Hashirama to do the same.

Personality
Hashirama's father appeared to be a stoic and calm man but was also quite stern and somewhat belligerent. He lost his temper and even went as far as to hit his son Hashirama when the latter brought up the subject of using innocent children as shinobi, believing that they had died true shinobi and would not stand for his son besmirching that memory. He believed that raising your children to be the best shinobi they can was the greatest love a parent could show for their child.

Appearance
A man of tall stature, he also possessed dark eyes and shoulder-length black hair kept back out of his face by a piece of cloth tied around his forehead. He also had a prominent jawline and wore the 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.

Abilities
Not much is known about his abilities, but the fact that he carried a sword on his back indicates that he practised kenjutsu.

Quotes

 * (To Hashirama) "What we're doing is simply being respectful. Once you set on the field of battle, regardless of age, you will be treated accordingly. Raising our children into capable shinobi… is the most sincere form of love a parent can give!"
