Reddit reviews Hunter x Hunter, Vol. 23 (23)

Togashi does redraw on the volumes, but you didn't negate what I said infact you further expanded upon what I said. His art develops over time (over all these years.) When Togashi publishes a volume he's had those serialized already in Shonen Jump for quite a while and for years. Here's one exmaple: volume 33 didn't get released in Japan until last June and those chapters came out years ago, except for 350 which came out this year but the other chapters came out years ago. But regardless, it still doesn't matter that chapter 350 came out this year why? Because he might retouch on the volumes if needed. So regardless, it still is how his art of now which has changed compared to the last time he was doing anything with hunter x hunter chapters. This has been happening for a long while. And you have to understand that Thunder.

As for Pitou on how she looks, my point still stands. Togashi changed Pitou's character design over all the years. Here is her older character design. And black orbs don't matter, its not like it had anything quintessential to the overall plot, arc and grand scheme of things. Its just the design Togashi went with back in the days. Here's on a simple volume cover:

Yes Pitou does have character traits of a motherly figure but... but many times throughout the series she's referred to as male not female. Just like the same thing with Alluka and Kalluto. Also, in Togashi's other series Yu Yu Hakusho he's done this with Miyuki and as well as Togashi's other series Level E he does it too. And in a lot of panels from the manga her body is shown a lot of times to be male. Like sometimes to have no breast and etc. Her breast started to show when Pitou started to undergo a new look like the same look in the later phase of the Chimera ant arc. And just like other characters looks might have subtle or drastic changes and doesn't evolve into different character designs but instead its abruptly changed because again the Togashi has and when he produces chapters. The others characters get different looks throughout the series as well, subtle or drastic it's obvious again because when he produces chapters are far apart from the other chapters. Again your just furthering my point. Again, Alluka and Kalluto look like females but are male and as well Miyuki from yyh. I mean if you don't believe me, just search it up for yourself.
