Saitama: This Substitute Will Only Be Useful from Time to Time!

I am Saitama, a man who broke through the limiter through exercise and became a hero. But the life of being invincible in the world is becoming more and more boring, and all the weirdos can't stop me from punching me. One day on the way to grab the specials, a purple muscular man suddenly appeared next to me. I couldn't hit him, but he didn't hit me either. If I felt carefully, I seemed to be able to control his actions with my mind! Although I don't know what the use is~ This novel and its characters are purely fictitious.
