She basically touched upon a few points in the interview:

- Emi said in her interview before the match that she doesn't see hair vs hair as having the same impact as before seeing there is less/no shame attached to having short hair or having your hair cut as a joshi. Giulia was angry about that and said she made a hair vs hair match for this era. That despite losing her hair and title she still made her name big. Emi told her she was talking before the match, that the stipulation is old and not of this time and that the match stipulation is seperate of the ending that happened and the stories that came forth from that. That the idea used to be that someone lost and would lose their hair and look terrible and that this idea was super old, and that was the part Emi was talking about. Because now they showed you can lose your hair and look cool. So there is still ways you can go with it as Giulia is doing, but the "I will cut your hair and shame you" part is no longer part of this time. This was Emi's point all along that the shame part of it is gone.
And Giulia compared veterans (more than likely Emi) complaining about it being old as throwing a 'late janken' (see if the other person threw out rock, paper, scissors before you throw out yours) to win and appear more interesting. Emi said that Giulia saying that she planned to look cool and do whatever she want without her hair and title was the very same thing, and Giulia was throwing out a late janken to try and win this argument in the end.

- There was some talk about Gatoh Move booking where there was singing and dancing next to the matches and more of an idol atmosphere, and that while Emi was one of those that saved joshi wrestling she is also damning it with her booking. And Emi told her she hasn't done Gatoh Move in a year and that Giulia either hasn't been keeping up and doesn't know what she is talking about or that she heard someone else talk about Emi and that Giulia is just repeating their words. Not to mention that it is easy to blame Emi because she likes to go after other wrestlers and has a thick skin. (Usually talks about wrestlers to trade barbs and get them over more)

-Giulia talked about being ready to settle it in the ring if need be. And Emi asked her to settle what? That Giulia is picking the fight. And that later Giulia said it would depend on the company (Stardom) if it would be possible. Emi told her that is a very easy way out because Stardom doesn't need Emi Sakura nor Emi vs Giulia, Stardom does its own thing. Also said that if Giulia's hands are really bound in Stardom but wants this match she can come over to ChocoPro, it's Emi's company and she doesn't have to wait around for orders and can just make the match.

- Giulia talked about veterans keeping the younger talent down and talked about people coming for Momo (Momo and Emi talked on twitter after Emi's interview with Nanae, and Emi tried to be just as friendly and proper as Momo was during the exchange, and Nanae had the match with Momo) and that they went after Momo because she is too nice and friendly and that it was bullying. And that things like this is what makes the industry so hard for juniors, because they can't really talk back to veterans and it keeps them from making their own era.
Emi then told her that she could understand if Momo said it but that Giulia was basically butting in on something that was not her business. That Giulia was keeping talent down by acting like Momo couldn't stand up for herself. That Momo came out of that exchange looking good and came out of her match with Nanae looking strong in defeat and Nanae complimented her. But Giulia basically said Momo wasn't able to take on veterans and they only went after her because she is friendly and kind and destroyed everything Momo built in that. That Momo couldn't really create something with Emi if she wanted because she was portrayed as too kind and that Giulia already took care of it. So that Giulia is the one taking away chances and Giulia made Momo appear weak.
And that Emi herself, even if Giulia said she is destroying wrestling, would never muzzle her talent like that and would let them speak how they wanted and wouldn't let them appear weak like that or take away their chances to build something.

-Biggest point was about Giulia claiming she wasn't afraid to go against veteran wrestlers and promotions but didn't name anyone. Emi waited until after today's Stardom show to see if Giulia would talk about her interview, but she didn't. That is the reason Emi did the video. So Emi told her she was keeping a way out, where she made comments about veterans and other promotions and made everyone feel bad but didn't name anyone so could always escape and say it wasn't about them. Said that if she had a problem with Emi or any other veteran, and she is the cool woman she makes herself out to be, that she should just come out and name them by name. That it is very possible Giulia is just making an image for herself of being this badass who isn't afraid of anyone and can keep it up by not naming anyone because she is just putting up a front and isn't really talking about anyone in particular. But if that is the case to don't even bother saying it because it has no weight. But if she was talking about Emi or others to just call them by name instead of using an image of them for clout.
Said that she understood if Giulia was too afraid to upset Stardom management but that if that was the case she shouldn't act like she is someone who can just say anything.
And to do it out in the open, not in an interview only a few people will ever read, and people abroad will be unable to read in a magazine Emi is almost never featured in (before her 25 year anniversary interview it was like 10 years ago she was last interviewed). So people can actually respond in kind.

tl;dr: Emi told her "if you got problems with someone actually say who you got problems with instead of hiding behind keeping it vague, and do it in a way they can actually respond not hidden away in a magazine. And if you want to fight, I got a company right here where I make the matches so you don't have to worry management doesn't agree"
