Butsuma Senju

This Senju member is the father of Hashirama Senju, Tobirama Senju and Itama Senju. He was the leader of the clan prior to the formation of Shinobi Organisational System.

Personality
Hashirama's father appeared to be stoic and calm, but lost his temper and even went as far as to hit Hashirama when the latter brought up the subject of using children as shinobi. He had no objections to the idea of young children being used, even saying that Kawarama was a worthy shinobi, not a child. He also seemed to be very stern because of the fact that he had no remorse for Kawarama's death.

Abilities
Not much is known about his abilities, but since he was the leader of the Senju Clan, he must have been a very powerful shinobi. He carried a sword on his back, which is an indication that he was skilled in kenjutsu.
