The Retirement Life of a Uchiha Ninja

After the Warring States-era ninja Uchiha Toru died, his chakra did not dissipate, and his soul did not enter the Pure Land. Instead, he became neighbors with the Sage of Six Paths. He watched several ninja wars unfold and saw what became of his descendants. But after everything had finally settled, an unknown "rage" overwhelmed him and he lost consciousness. When he woke again, he was no longer in the ninja world, and his life seemed to have started over. Warnings: 1. The protagonist is a widower from the start. His relationship with his late wife is complicated. He has a best friend in the Naruto style, but that friend has died. He has a son, a daughter, and an adopted son, so this could loosely be considered a child-rearing story. His son is Uchiha Kagami (Shisui's grandfather), his daughter is Uchiha Kana (Obito's grandmother), and his adopted son is Jin (a JJK character). 2. There are many storylines where he transmigrates into parallel Naruto worlds. This may not really be a warning, but I figure people might get tired of seeing this trope, so I'll mention it anyway. 3. Some aspects of the setting are the author's own creations. Those who support Asura's line may not like the way Konoha is portrayed. Please keep the discussion civil. The author is very sensitive, so if you don't like it, please leave quietly. Thank you. Theme: Fulfilling a dream, childhood memories
