After the battle between Madara and Hashirama in the Valley of the End, a weakened and gravely wounded Madara finds refuge in a samurai village almost outside the territory of the elemental nations. Hidden away, he finally lives in peace, seeking everything he couldn't achieve during periods of war and vengeance. He falls in love with a samurai from the Uzumaki Clan named Miwa and eventually has a son named Hitoshi, whom he raises with all the love possible.
Hashirama had two daughters with Mito, but during a mission with Team 9, the team was surrounded and their bodies were found dead, except for his daughter. They concluded that she had also been killed, but instead, she was found kilometers away in the same samurai village where Madara and Miwa were. As a final apology for everything he did to Hashirama, she takes care of his daughter.
Hitoshi and Asahina, after years of living together, training and doing missions for fun, had a son and decided to go to Konoha after years, after the wars between the nations had definitively ended. Unfortunately, after a few months of living there, they were attacked by the large and powerful Kitsune no Yoko and met their end, but not before having a child. The child's name?
