We've finally reached the end of this travesty of a manga. When this first came out I was more excited for a series then I'd been in years. Something that broke the mold, turned a genre on it's head. Instead, what we got was:
1. A super hero who lost his secret identity 1/4 of the way through the series, with no repercussions
2. The same guy who was supposedly a master of monster anatomy, resorting to just punching them extra hard
3. The literal first villain in the series becoming the final boss with zero character development
4. An extra super secret true final boss which has so little personality it didn't bother to even speak
5. The mystery behind the MC's powers and how it is tied to the secret boss not actually mattering to how they take it down
There were so many missed opportunities for a promising series only for it to devolve into shonen "this time I'll punch you even harder" battle B.S. The lost potential just makes it hurt all the more in hindsight.
