One-Punch Man: My Underling Is in Your Care

I had an opportunity right in front of me, but I didn't know how to treasure it. The System asked me to choose a character, and I sneezed, turning Saitama into Tanktop Master. So be it. From the start, all I have is a tank top. As long as I push the power of the tank top to its limit, what is Saitama to me! Boros would run all the way back to the moon when he saw me, and Garou would do anything to become my underling. Even Tatsumaki is my little fangirl. Thanks for taking care of my underlings. The tank top is justice.
