Celebrity Streamer of Parallel Time and Space

An otaku who was reborn in a parallel world and had a super system would start as a streamer and become a super streamer.

He had been in the entertainment industry and became a superstar. Everyone said that he was a genius in the entertainment industry.

The protagonist looked down on him with an invincible attitude, making everyone pale in comparison.

He was a piano grandmaster, a music grandmaster, a martial arts grandmaster, and perhaps even a martial arts expert. Everyone thought that he was an all-rounded genius, but only he knew that he was not a genius at all. It was all thanks to the system.
