My Old Enemy and System Is Saitama-Sensei

Teacher Saitama is sitting opposite me! Said that I was his fateful enemy... (ʘωʘ‖)՞Holy shit... I'm scared... I couldn't tell from his bored expression whether he was serious or not... I was targeted by Saitama... I'm really scared... Will he suddenly punch me... What to do? Waiting online... Don't dare to move... (Magically modified anime world travel flow: The first world is Naruto, which is in progress. He became the second brother of Uchiha Sasuke! Forget it, but the Uchiha Husky and Uchiha Caucasus that he met next? There are actually Uchiha Corgis! Is it appropriate for Otsutsuki Liu Neng and Otsutsuki Zhao Si to be so powerful? I don't accept it, I want to become stronger! Oli is here!!!)
