Tobirama is eight years younger then Hashirama.

Four years younger then Uchiha Izuna and seven years then Uchiha Madara.

She is born with red eyes and white hair in the middle of the winter and five minutes younger then Senju Itama. She must hidden her true gender!

He died when he was five, less than two weeks after Senju Kawarama, who was two years older.

Two months later, she finds out that his only older brother is meeting an Uchiha, and they're laughing again. As he finds out years later, one of his two soulmates.

The Uchiha worship the children of Amaterasu, as Tobirama is one, but she is forced to conceal his true appearance and hide. She has always been able to hear the goddess's voice, but was rarely able to do anything, and so years will continue to pass in hiding.

The Uchiha have had no idea about this all these years and assume that Tobirama is the same age or at least a year or two younger than Izuna.

The meeting at the river showed no signs of this, nor did the following nine years on the battlefield, as Tobirama knew how to compensate for his younger body and the resulting disadvantages compared to Izuna.

His father also saw it as a sign of pride and great power, which is why Tobirama became the youngest shinobi ever allowed on the battlefield.

His older half-sister, Hatake Miraka, and soon-to-be sister-in-law, Uzumaki Mito, also helped her, and her talents in the Hatake legacy and the art of seals were quickly recognized.

When the peace talks finally began, the Uchihas demanded the Senju, who is Madara and Izuna's soulmate, as collateral. The Senjus agreed, but on the condition that the wedding would not take place for three years, as the requested person was only 14.

The Uchihas accepted, but demanded a written engagement and a guarantee that the person would move in with them once the contract was signed.

Thus, the peace treaty was finally concluded, and the Uchihas learned the truth about Senju Tobirama and were more than shocked.

However, Konoha flourished over time, and Madara and Izuna became the proud fathers of five children. The eldest and next head of the Uchiha clan and the youngest inherited the Mokuton, and the second eldest and only daughter of the family was born with the Rinnegan.

The children's names are: Ryota, Izumi, Kewan, Itachi and Medan.

Tobirama also became very happy and, over the years among the Uchiha, better understood what Amaterasu meant when she said she would never harm her if they knew about her. She also quickly realized that Madara and Izuna are very good and kind people, and that one simply has to behave differently on the battlefield than one does in private. The others also appreciate her more, and she, her children, and other descendants are fully accepted.

Hashirama also found happiness with his soulmate, Uzumaki Mito, and they unfortunately learned that the third member of the soul bond died at a very young age.

Hatake Mitaka also found happiness and liked to make fun of her younger half-sister.

In the end, everyone had their happy ending, and Konoha will survive for a very, very long time!
