Legend has it that if you dye your fingers blue and form a diamond-shaped window, you can glimpse the bygone time and old friends.
For Uchiha Madara, Senju Hashirama is the young boy drifting by the Nanga River, the opponent facing each other in the Valley of the End, and the only warm light that he can see through the "Fox Window" that illuminates the loneliness in his heart. And this window also reflects Senju Tobirama and Uchiha Senna - the two most similar souls, struggling between family justice and personal emotions, and finally settled on the eternal look that the Flying Thunder God slashed.
Time goes by, three years in Konoha, six-year-old Chie Uchiha is reborn with the memories of her past life, and meets Senju Nagawa in the ninja school. Two children who are supposed to be facing each other, what kind of unexpected future will their windows of destiny reflect?
When three generations of love, hate, anger and obsession are destined to separate, or is it possible redemption?
