Go Back Infinitely to Ten Minutes Ago

I am extremely smart, but cautious, and will always dare not move forward in the face of the unknown. Without the opportunity to try and make mistakes, I will never gamble with my life.

Yes, although I am just an ordinary person, I can easily handle any plot; facing any enemy, I can attack with one hand, and I am invincible, because I am called fearless!
