The story I imagined before the founding of Konoha belonged to the legendary ninjas of that legendary era.
Ahem, sometimes I wonder how sweet it would be if Itachi and Sato could grow up together, but AB has given the brothers the best ending, and their ancestors are more miserable...
Since AB has not described the previous events in detail so far, it is unlikely that he will spend more time drawing them in the future. There is quite a lot of room for creativity in making up (crossing out) ideas, so here I will complete another part of the reincarnation of the Uchiha brothers~
