Yeeaaa...I'm all for comedy, but this feels too forced. Every time he shows his power every other single person just "happens" to be looking somewhere else, or just denies what they see with their own eyes. It just doesn't have the same quality comedy one punch man has. Also, there's no way that you can be that dense. You can destroy mountains by throwing a small ball at them, and everyone reacts shocked when it happens. Plus no one does anything even close to as destructive as that. Yet he still believes he's oh so weak...
I really hope this is just the setup for the big reveal that he's actually strong, but I have a feeling that I can already predict how this manga goes, based on the chapters so far and the title. Which is that this will be the entire story. He keeps on being a one punch man clone, except no one will ever see and/or believe it. So he will remain a "failed knight" and will keep believing that he's weaker than all those other "strong" adventurers.
Pretty much spot on with what I was thinking. I was hoping this would be something else, but it has the makings of a gag manga.
I was hoping he'd realise he's not normal after he broke the records on the exam, but instead of that they're just going to completely deny everything he's done. This feels like a repeat of One Punch Man, except they at least had the brains to actually say: yeah he passed everything with outstanding results.
