Senju Tobirama was reborn after the Fourth War, but something went wrong for some unknown reason. In this life, his tear ducts were very developed, and he would shed tears uncontrollably if his negative emotions were slightly stronger than before. This seriously affected his bluffing momentum during a quarrel (?) However, he Senju Tobirama never expected that Uchiha Madara, who destroyed heaven and earth and destroyed mankind, was actually afraid of others crying.
Tobirama: Have you discovered a way to "control" Uchiha Madara?
