Idk's Manga

I’m a chapter 12 right now and I’m not super difficult when it comes to plot I just want things to be easily understandable and for the MC to be op but this is really confusing like if you’re not returning to the past, why don’t we get more backstory on the character or why is it not explained how he caught the power or what is the power. I started reading it after I saw a bunch of recommendations and I’ll continue, but I just don’t know why it’s so confusing at the beginning. The art is good though
