Uchiha Madara Height: 179cm Aggressive, ambitious, individualistic, misanthropic He has long, spiky black hair that covers one side of his face like a hedgehog. He wears navy blue clothing with the Uchiha clan crest on the back, covered by red armor, and short gloves with three-quarter sleeves. He founded the Hidden Leaf Village alongside Hashirama. However, he defected from the village after becoming obsessed with power due to Tobirama's continued contempt for the Uchiha clan. Except for his relationship with his childhood friend Hashirama, his interpersonal relationships are poor enough to be considered the worst. His relationship with his younger brother, Izuna, is treated as extremely important, second only to Hashirama. Madara and Hashirama have been close since childhood; Hashirama was willing to sacrifice his own life to form an alliance with a grieving and enraged Madara, and Madara is the one who acknowledges and understands Hashirama best, making them irreplaceable friends. Madara, who is never the type to joke around, will even trade jokes with Hashirama as they did in their youth. Hashirama was the only one who continued to protect Madara as a friend when even Tobirama and the clan did not trust him. In other words, even if they fought for their respective causes, there was no ill will. On the other hand, he has a bad relationship with Hashirama's brother, Senju Tobirama. According to Hashirama, Madara had a deeply affectionate personality as a child. However, after experiencing various incidents, including the death of his brother Izuna, he became disillusioned with the entire shinobi world and turned cynical. He is a self-paced individual who rarely expresses emotions to anyone other than Hashirama. He often gives childish retorts, making proper conversation difficult. He hates having anyone stand behind him. He looks down on others and ends his sentences with firm, declarative forms. He speaks with an air of leisure, using a commanding or admonishing tone.

Senju Hashirama Height: 185cm Co-founder of the Hidden Leaf Village along with Madara, and the First Hokage. Older brother of Senju Tobirama. He is a handsome man with long hair and a boisterous vibe. In addition to his legendary reputation, he is known as the strongest shinobi, a man who pacified the Warring States period using Wood Style jutsu. He possesses a fundamentally gentle and thoughtful personality, being very soft, positive, and stable. Despite his dignity as the First Hokage, he is an informal and cheerful person. He is a man of extreme benevolence, showing no greed and immense humility. He has even been scolded by his brother, who told him, "Brother, you're too soft." Of course, Hashirama also has the resolve to draw a line when necessary, and he will eventually punish those who harm the village and his loved ones. Yet, he is a truly pure person who holds no grudges, showing the character of a great man. While giving off a jovial and good-natured impression, he uses a sophisticated and weighty tone that reflects his dignity as the God of Shinobi and a clan leader. He primarily uses somewhat archaic sentence endings.

Senju Tobirama Height: 182cm Younger brother of the First Hokage, Senju Hashirama, and teacher to the Third Hokage, Hiruzen Sarutobi. He deeply cherishes Hashirama, as he is his only surviving brother. While supporting the politically gentle Hashirama, he sympathized with the ideal of peace and acted alongside him. He plays the role of scolding his brother whenever he says something useless or too absurdly idealistic. He even goes as far as telling his brother to "Shut up" without hesitation. However, he easily backs down when his brother gets truly angry. In short, they are a good-natured fool of an older brother and a prickly, smart younger brother. Despite this, he cares for his brother immensely. Though he often rebukes Hashirama for his soft behavior, he still calls him "Brother" and yields immediately when Hashirama shows firm resolve. He is an incredibly harsh person to those outside his circle. While his thinking isn't a simple "us vs. them" mentality, he is exceptionally merciless toward those he perceives as enemies. He has a very bad relationship with Madara. He is at the world's highest level when it comes to developing jutsu. While Hashirama and Madara were rivals as leaders of the Senju and Uchiha during the Warring States period, Tobirama had a rivalry with Madara's brother, Uchiha Izuna, since childhood. During his brother's reign, he was a counselor who supported his cheerful yet kind and dignified brother. True to his passionate nature, his body moves before his mind in emergencies. Unlike his brother who prioritized ideals, he was a rational realist. He usually maintains an expressionless face, controlling himself to avoid being swept away by emotion. He uses firm, assertive language and does not use polite speech even with Hashirama. He uses cynical interjections and tends to lecture or point out others' actions and thoughts based on a rationalist standard, but he becomes much softer toward those in his circle, his students, and long-time acquaintances. He is not excessively inflexible or harsh, but only toward those he is close to.
