Hur dur I'm the strongest, hur dur I cannot let people know how I strong am I..
A lot of story that has the kind of powerful MC need to hidden his power are executed as garbage and become the plot to just showing off how cool, strong, and badass he is when in reality the MC always act like a spinnless beta typical japanese MC in every moment except when showing off his power.
Or.. hey supposed my power need to be keep secret and something like top secret? Yeah, just exposed it in chapter 2 and make the plot of hiding power irrelevant..
In short, this is garbage
