Wait a minute, so basically based on japanese language hisoka is using female pronoun while machi is using the male ones when talking? They're so alike in a way...
Wait wait, let me clarify. I think you mixed things up here.
Hisoka uses boku and kimi as his pronouns. They are masculine Japanese pronouns but not as rough as the pronouns ore, omae, temee, kisama. This suits him because of his childish behaviour and tendencies, though fcked up. (I mean, he's like a fcked adult child so........)
He hovers between masculine and neutral speech but he does sometimes use or switches use female speech endings.
The most prominent one where he used female pronoun is when he was battle horny with Chrollo in York New arc.
This is part of what he said when Chrollo fell for his sword of law bs trap in anime, which idk if it's the exact same dialogue in the manga (I might have some particles wrong or missing or some stuff wrong, so forgive me since I'm only going off based on my memory):
やっぱりいいよあなた. 絶対あなたはボクが殺る. (Yappari ii yo anata. Zettai anata wa boku ga yaru)
'As expected, you're great, my dear. My dear, I will definitely kill (do) you.'
Note: to kill verb here is pronounced as yaru, which also sounds rhe same as the very informal version of to do verb, which is also yaru.
Anata is a feminine pronoun of you. 99% wxclusively used by women or people who want to sound feminine or identifies as one. Men might use it in real life in situation where they have to be polite and formal. In fiction, men may use it to let other knows that 'hey I'm not exactly a man' or hey, I'm not rude, I have respect and not a ruffian exactly.'
(Men uses feminine speech when they have to be formal like speaking to people in charities, being a host and all, as well)
Anata is also used by females (or those who are feminine whether they be homosexual or trans) to call their significant other. When they use it in this context, it means 'honey, dear, sweetheart' or whatever affectionate words to call your s/o is out there.
So yeah............ Hisoka..... used anata in that scene when talking about Chrollo......... not just for second-person pronoun..........
Anyways, Hisoka mostly speaks in masculine and neutral language speech, but sometimes does use female language.
Machi on the other hand used masculine language when she was a kid and, masculine and feminine language as an adult.
Kid Machi talks almost like Uvo ahahhahahaha.
お前がやれ！- Omae ga yare - You do it!
いやだ. - iya da - No/No way
Omae is a very masculine pronoun, much more than boku and kimi. And Yare is also a very masculine command, given its verb conjugation. And the sentence ending -だ is also masculine. Machi as a kid speaks so much like a guy xD Hisoka (adult one) doesn't speak very masculine which is makes sense since he wants to sound playful and all xD
Adult Machi is different from child Machi. Adult Machi uses atashi, which is the informal version of watashi, and anta, the informal version of anata. Clearly her pronouns are not very feminine but feminine enough.
And here comes the interesting thing, she still uses masculine speech but with certain people, she uses feminine speech.
She uses a bit of feminine speech with Pakunoda. With Gon, she does as well, when she corners him with Pakunoda and asks him if he knows about the chain dude. We see the same thing with Feitan when they continued walking together and left Franklin and Nobunaga fighting when they were otw to York New. She also spoke to Kalluto in female speech back in Greed Island.
But the most she spoke with using feminine speech is Hisoka. I repeat. Hisoka.
One thing I observed is when she speaks in feminine speech, she either is close to whomever she is soeaking to or is showing consideration.
We can tell that she shows consideration with kids based on the fact she uses a bit of feminine speech when speaking to Gon (can someone remind me if she also spoke to Killua directly? I think she only spoke to Gon directly during York New arc when the Troupe caught the teo of them trailing them).
We see the same thing when she is speaking with Kalluto. When she said to him to come out, 出といで, for instance. She spoke a bit in female speech. Not that much. But we can see that they are not close, which means she's being considerate to him. I mean Kalluto is a kid..........
As for Feitan, I'm on the fact that she's showing consideration because she's seeing him as an adorable kid due to his height. I don't think they are close like to the point of sharing a few secrets or something like that, no. So far, no evidence they are. So, I'm on she sees him as a kid due to his height and softens up team xD
As for Pakunoda, it makes sense if Machi is close to her even if it's just a little bit. I mean Pakunoda was probably the big sis who helped her out when puberty hit her or whenever there are girl problems she has to resolve. I don't doubt if Pakunoda was also the one she confided with when she fell for someone *ahem*
And as for Hisoka. Oml, Machi spoke to him in female speech all throughout before the Chrollo vs. Hisoka fight.
This is how I came to the conclusion that when she speaks in female speech, she is close to them or trust them to some extent - based on the way she spoke to Hisoka.
On chapter 55, when she made her first appearance in the manga, quite a number of her dialogues are in female speech.
Even during their conversation in Greed Island, she was using female speech.
But after the Chrollo vs Hisoka fight, she would speak to him in masculine form. Sadt. I assumed it was because she knew that might be their final interaction and their relationship will never be the same again. Rip.
Maybe her speaking in female speech just means she's showing consideration to him like how she does with kids but man the amount of female speech in her dialogues tells me otherwise........
She would also speak in very rough masculine speech whenever she is very pissed or angry. You can even tell she's pissed or annoyed when her masculine speech becomes rougher.
For instance, in York New arc, when Franklin asked if she knew whether Hisoka is coming to the meeting and part of her answer is
あたし聞くな！ - Atashi kiku na! - Don't ask me!
聞くな is a command form of to listen 聞く but among the masculine command conjugation, it's on rougher side.
And when Machi is speaking in a rougher masculine speech, she doesn't use アンタ (Anta), she uses the pronoun, テメエ, Temee, instead.
Now who uses Temee when they're pissed or annoyed?
When Machi got pissed a bit at Nobunaga when they were arguing about the 'chain dude' on whether they will be recruited by Chrollo or not, she used Temee on him.
Basically, the more pissed or angry she is, the more her speech tend to resemble Uvo's.
This is apparent when she got angry at Hisoka when he declared war on Spiders.
Zakk.....kken ja nee!!!! Ima atashi ga koroshite yaru!!
Mate!! Modore temee!! Kore hodoke korosuzo GORAAAA!!
Did you hear Uvo when she was saying those Japanese lines especially the one with GORAAA in it?
That's how you know that Machi is super pissed and angry at you.
Which means when she was talking to Hisoka back in Greed Island, she wasn't even pissed lmao ahahahha
I hope this clarifies any misunderstandings and confusion about Hisoka and Machi way of speech.
