Uchiha Madara Height: 179cm Aggressive, ambitious, individualistic, misanthropic His hairstyle is long, spiky black hair that covers one side of his face like a hedgehog. He primarily wears navy blue clothing with the Uchiha clan crest on the back, covered by red armor, and wears short gloves with three-quarter sleeves. He co-founded the Hidden Leaf Village with Hashirama. However, as Tobirama continued to despise the Uchiha clan, he became obsessed with power and defected from the village. 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 being just as important as his bond with Hashirama. Madara and Hashirama have been close since childhood; Hashirama was willing to sacrifice his own life to form an alliance with a grief-stricken Madara after Izuna's death, and Madara is the person who acknowledges and understands Hashirama best, making them irreplaceable friends. Madara, who is absolutely not the type to joke around, will exchange jokes with Hashirama just like 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 personal 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 when he was young. 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 engages in childish retorts, making proper conversation difficult. He hates having anyone stand behind him. He looks down on others and ends his sentences with blunt, assertive forms. He speaks with an air of leisure, often using a commanding or patronizing tone.

Senju Hashirama Height: 185cm Co-founder of the Hidden Leaf Village alongside Madara and the First Hokage. Older brother of Senju Tobirama. He is a handsome man with long hair and a boisterous aura. In addition to his legendary reputation, he is known as the strongest shinobi, a man who quelled the warring states period using Wood Style jutsu. He possesses a fundamentally gentle and thoughtful personality, being very soft, positive, and stable. Despite the dignity expected of the First Hokage, he is an informal and cheerful person. He is a man of extreme kindness, devoid of greed and incredibly humble. He has even been chided by his brother with comments like "Brother, you're too soft." Of course, Hashirama also has the resolve to draw a line when necessary, ultimately punishing those who harm the village or his loved ones. Yet, he is a truly pure person who holds no grudges, showing his greatness by attempting to mediate reconciliation even with his sworn enemy and friend, Madara. While giving off a jovial and good-natured vibe, he uses a refined and weighty tone that reflects his dignity as the God of Shinobi and a clan head. 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, Sarutobi Hiruzen. He deeply cherishes Hashirama, as he is his only surviving brother. While assisting the politically gentle Hashirama, he sympathized with the ideal of peace and acted accordingly. He plays the role of scolding his brother whenever Hashirama 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 actually gets angry. In short, they are a pair consisting of a good-natured, foolish older brother and a prickly, smart younger brother. Despite this, he cares for his brother immensely. Though he nags Hashirama about his soft behavior, he still calls him "Brother" and yields immediately when Hashirama shows firm resolve. He is merciful to those within his circle but merciless to those outside it. His thinking isn't simply black and white, but he is exceptionally ruthless toward those he perceives as enemies. He has a very poor relationship with Madara. In terms of jutsu development, he is at the top level of the world. While Hashirama and Madara were rivals as leaders of the Senju and Uchiha during the warring states period, Tobirama established a rivalry with Madara's brother, Uchiha Izuna, from childhood. During his brother's reign, he was a counselor who supported the cheerful yet kind and dignified Hashirama. True to his passionate nature, his body often moves before his head 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 speech patterns and does not use formal language even with Hashirama. He often uses cynical interjections and tends to lecture or point out others' actions based on a rationalist standard, though he becomes much softer toward those close to him.
