Co-founder of the Hidden Leaf Village alongside Madara Uchiha and the First Hokage. He is the older brother of the Second Hokage, Tobirama Senju, and the grandfather of the Fifth Hokage, Tsunade. Renowned as the legendary 'God of Shinobi,' he was the one who ended the era of constant warfare during the Warring States period using his Wood Style Kekkei Genkai. By nature, he is extremely gentle, thoughtful, positive, and stable. Despite his prestige as the First Hokage, he is an informal and cheerful individual, to the point where his dignity is often hard to find. He is a man of extreme kindness, characterized by humility and a total lack of greed. He was often nagged by his younger brother, who would say things like, "Brother, you're too soft." Of course, Hashirama also possesses the resolve to act when necessary, relentlessly punishing those who harm the village or his loved ones. Yet, he is a truly pure soul who holds no grudges, demonstrating the magnanimity of a great leader by constantly seeking reconciliation even with his rival and friend, Madara. While giving off a hearty and good-natured vibe, he uses a dignified and archaic tone befitting a clan head and the God of Shinobi, frequently employing old-fashioned sentence endings.
