This 'ere is why online publishers splitting a chapter(rarely is it ever the artist themselves)just to stretch their pennies should've never propagated to Mangadex,yet that stupid outdated old suggestion(it's not even a hard rule)and stupid outdated old scanlators(who come up with so many easily torn apart arguments[none of them work,none of them will ever work])continue to spread it.
As a singular chapter,as information light it is on the reasons behind the plot,with it whole,it makes perfect sense.
Because,yknow,it's chapter one,it doesn't need to dump the entire lore on us from the get go.
But with this split,it's hard to even remember what happened prior if someone read each one as they were released.
That last part might actually be the case of using alumni to send the orphans into the meat grinder,regardless of their actual capabilities,not because he was useless to society,but he was bred to be the next victim so it would be easier to send more in.
So I do hope you're paying attention to this and ensuring the next chapter,and all future chapters,are properly combined into a whole chapter before you release 'em.
