Senju Tobirama was reborn, Senju Tobirama was very troubled.
Now that we know the beginning and end of the Fourth War, we cannot repeat the same mistakes. Although I really don't want to admit it, I did kill Uchiha Izuna, taught Danzo's children badly, and planted the seeds of hatred, which made Uchiha Madara angry and the newspaper office was exploited, and was one of the main culprits that led to the outbreak of the Fourth War with countless casualties.
Uchiha Madara does hope for peace, and the Uchiha clan is not an evil clan. So the best thing to do now is to sincerely form an alliance with the Uchiha clan. However, how to make his sworn enemy believe that he has abandoned evil for good (?) And truly wants to be friends with him? Or at least let the enemy know that he really agrees to form an alliance? Today's Tobirama Juju is still troubled.
