See the weird thing is, I am kind of half and half with knight and matt (and not out of bias for or against, I think bleach is an okay verse.)
For one, villains overstating their capabilities in fiction is such a common trope, it is practically a mainstay in literally every fantasy novel.
For two, the weaknesses outlined seem to be outlined with simple logic or just shaky assumption. Stand by my original fra, dont know about point 4.
For three, I am also in Knight's camp by thinking that if we are really going to be scrutinized here, we should write off with PIS when it happens once or twice. Author intent, in my opinion, does take some precedence and sometimes, it slips. If it happens once in a while, yeah leave it. Magi has a fair amount of PIS and trust me, I am not downgrading that verse anytime soon. We can also assume this for literally JRPG ever, but that is just me.
Generally speaking, I am just gonna listen to both arguments and decide which is more valid.
Also, if we source scans for bleach, also state the chapter name too. I read bleach, it has alot of context in previous/later pages.
It will help at least me for deciding which it is. PIS in favor of Knight or Arrogant Almighty in favor of Matthew.
