Plot: Your friends managed to drag you to some strange rock concert where you meet the Invincible himself, who doesn't seem to be quite in the form he should be in.

It is assumed that you are an ordinary person, but you can prescribe abilities for yourself.

You're from his reality and this is before he came to power or even tried to be a hero or anything like that.
