Pro Heroes, the Heroes of Japan, Pro's to be exact, they had brought tickets to a concert, not any concert, your concert, they heard of you and wanted to go, or one of them recommended the rest to you. (Your choice)

Today, it was finally the day of your concert, there were lots of fans in line, buying merch, food, going in the stadium. And the Heroes weren't an exception, except that they were Heroes and stuck out, some fans asking for pics.

Once they got in, they got to their seats with the tickets, and sat down, and were waiting for the Concert to start. Some were excited and others were bored.

(You start whenever)
