Chapter 78 dropped. As always, sorry for any translation errors.
  • Chapter begins following the end of the previous one, with Akito asking who's that person, who answers she`s an elementary school teacher;
  • Akiba explains to Misato that Akito was cheating( the diluted Tequila thing). She noticed there was something off, and explains she switched the bottle he was having with something stronger;
  • Misato is perplexed that Akiba noticed that. Akiba explains that she noticed because observation is her hobby( Misato is surprised by this);
  • Misato asks if Akiba was also helped by Sousuke. She responds that yes, but more than that, Sousuke is a special person to her( notice that, in this part, Akiba addresses him as "Sousuke-san". First name. That's more personal);
  • Akito complains about being tied, and asks what will happen to them for doing that. Akiba reverses the logic and asks him what would happen if they leaked that Akito knew about Iwabuchi's secret;
  • Akito tries to brush it off as a lie told to put people into the drinking game. Akiba denies it, by showing him 2 other guys tied behind him, in a corner. They were hosts from other places, and used the same tactics, but were defeated in the same way. Both said Akito might know, as he was sniffling into Iwabuchi". Akiba asks if Akito has a grudge on Iwabuchi. If not, there was no reason for Akito to be sniffling onto Iwabuchi;
  • Akito confirms, by saying his younger sister, his precious family, was taken away. About six months earlier, she moved, and the reason he got was that "it was a big job for Iwabuchi";
  • Before her leaving, he managed to check on her phone and found out a lot of naked women photos. He did not fully understand at the time, but after searching, he understood that Iwabuchi thrived with taking naked photos of weak women;
  • What his sister uncovered was Iwabuchi`s server. And a file with his secret;
  • When asked what happenned to his sister( how was she the present), Akito says he doesn`t know, but investigated what happened after that;
  • He says she went with Iwabuchi to the Orgia party, but he doesn't know what kind of party is it;
  • Misato confirms to Akiba that's the same invitation she and Sousuke got;
  • Akiba says they'll look for his sister, and even a highschool photo of her might help;
  • Misato says they should hurry and tell Sousuke about this, but Akiba denies, saying that he, too, is busy gathering information;
  • Chapter ends with Akiba reinforcing that he, too, even now, is gathering information...while we see him STILL being suffocated in the girl's breasts, crying, saying he's dying...

Edit to fix some minor typos.

I want to make a correction about Akito's sister. She and Iwabuchi are going to go to this party. So they'll be a couple at the party that Soska will go to.

The image which shows iwabuchi and a women from back, when akito talking about her sister it's look like rika, what do you think guys ? What if the theory about the female cast in momonga account is not rika is become true ? Because that women could be akito's sister, she has identical look like rika, and rika just pull string from behind and shiratori or mori might be know about it but can't leak it to sousuke or might the doesn't know at all. Why i think like this because akito told her sister dissapear almost six month ago, (maybe i forgot, cmiiw) , since when does momonga account exist. But if i have approximately is nearly six month or less. What do you think guys ?

Momonga was active way before six months.By looking at her belly you can guess that and rika did have sex with shinjo with protection.There is not even a chance for it being wrong unless she has a twin.Dont forget she had sex with shinjo in the bar where everyone seen her.
Probably in orgia party some big shot politicians are also involved that's why she disappeared knowing she can't do shit or kidnapped.Most of the time politicians are portrayed as masochist so maybe they are rika's fans or just customers of the party

Please, remember that Sousuke saw the raw videos of Shingo and Rika on the SD card, during the spa trip arc. Even if Rika had a double, at least in one instance she did have sex with Shingo, if this was true.
Also, while we got Shingo's inner monologue in chapter 59, chapter 73 show us that Sousuke is aware of Shingo's side of the story. If Shingo did it knowingly or unknowingly, it doesn't exclude the video in the SD card.
If Shingo is somehow in a leash against his will( by Iwabuchi, or someone else), and did in fact hide that there was a double, it still doesn't exclude the raw video in the SD card.
Also, as @eren760 pointed out, by now Rika is about 5 months pregnant. If Momonga was 6 months old, considering Rika showed Sousuke the ultrasound of 2 months, It'd mean Momonga started 1 months before the Ultrasound itself. As this type of content is illegal, raising it's spotlight by paid traffic would be the only way it got good numbers fast, and it's out of the table. Only organic traffic.
Moreover, Shogakko starts at 6 years old, and Shiho is 7 at the start of the story, right? With Japanese School festivals happening about autumn( and in chapter 72, Sousuke pointed out it'd be weird for someone to be in the school, and saying it was already january), i'd argue that...if the story started in 2025, and now we're in 2026, Shiho met Tsubasa at about 2024. From there, it gives more room to maneuver their friendhip, and Rika and Shingo's eventual enrollment on the PTA. I'd bet, at the very least, Momonga started at the end of 2024.

So this means Akito's involvement with Iwabuchi is via coercion, with Iwabuchi blackmailing Akito by holding his sister hostage?

Which means that Akito isn't necnessarily involved with Rika directly then, correct? He's merely a stepping stone to Iwabuchi, who is the next target on the way to confronting Rika.

Which would explain why it's not Sousuke confronting him directly; if he's not a part of Rika's collection of villains, then Sousuke doesn't need to be the one to figure him out.

I wonder what Iwabuchi's downfall will entail, then--as I assume that, following precedent set this far, he has to be defeated; likely via some weakness, like the baldness or the "we'll cuckold you via your wife" stuff.

The question from there though, is whether Iwabuchi can be turned against Rika. The others sorta were, in a sense--at leqst enough that all the women have shown up to help Sousuke, if not the men themselves.

But is he the final step before Rika is confronted? Or will another surprise mid-level boss rear their head?

Also, is Sousuke just gonna be comically defeated by some random chick like this until one of his ally women come and save him? It seems like a weird bit of comedic relief, almost, unless that chick's got additional, ulterior motives to be smothering him for so long.

Siho is now 7 years old, but we don't know when she turned so old. If her birthday is between April and September, she's in first grade now, if her birthday is before April, she's in the second grade. In Japan, they start going to school at the age of 6. The school year begins in April. Many nuances indicate that Siho goes to the first grade.
From Singo's memories, he will meet Rika when their children were at school. Therefore, the Mamong channel was created not so long ago. In addition, we know of only four videos: "at school", "3 minutes", "in the park toilet" and "in the bar". It was created no more than half a year ago. And this is the period when sister Akito disappeared.
Now let's move on to the video with the sd card, on them we only saw a kiss, the sex itself was not shown there. Only in chapter 73, Soske says that Singo and Rika had sex, and that's from Singo's words.

This theory is plausible, but most of the commenters here don't support it. Most likely, Shiratori doesn't know about this; he was consulted by the real Rika about promoting his account. As for Shingo, Rika could have paid him to lie. Or he might not have realized there are two different Rikas. For example, the real Rika would go out to change before a video shoot, and the fake Rika would show up wearing a mask.We also don't know when Shingo testified, whether it was before the video of "his practice" was found or after. If it was after, it could have simply been revenge against Rika, even if he knew the truth.

As for Momonga's channel, we don't know when it was created. We only know that it was created after Shiho started school. If Shiho is in first grade, as many points in the manga indicate, then Momonga's channel is no more than seven months old. More likely, even younger, which is related to Akito's sister's disappearance.

As for whether Rika had sex at the bar, Shiratori said he doesn't know. Rika could have been consulting Shingo. Regarding the video on the SD card, we only saw a kiss. As for chapter 73, I already wrote about it above.

Continuing with Akito's sister, she'll most likely be playing Rika at the party, getting fucked by several people. This should break Sousuke's heart, since he won't know it's not Rika.

The main question is, why does Rika need this?
The main reason is that Soske has grown up, so that he stops behaving like a child. As we can see from the very beginning of the manga, Soske climbs into Ricky's phone, follows her, but he never talks to Rika about important topics. He is afraid to raise the topic of Matsuo's debt, Shiratori's consultations and interaction with Shingo.

Now let's move on to the video with the sd card, on them we only saw a kiss, the sex itself was not shown there. Only in chapter 73, Soske says that Singo and Rika had sex, and that's from Singo's words.
If her birthday is between April and September, and the story starts on these terms, as well as japanese children starting school at six years old, you got your answer that this is her second year. If it's her and Tsubasa's second year, than we got one whole year for them to form a friendship.
If not, it started as early as april itself( so about 8 months, before Shingo's defeat). Remember: at best, Rika is 4 to 5 months pregnant in the actual moment. It's impossible for her to have obtained so much audience in the short term we're dealing, with just 4 videos. At least not enough to have Shingo hooked instantly. Organic traffic, not paid one, it's what we're talking about.
Again, and this has been talked about a lot to you earlier: conjecturing is fine, but these delusions do not work anymore. We didn't know if Shingo's monologue would be accounted for Sousuke's understanding or just exposition to the public. Turns out, it was both. Rika was also not a pure victim herself, as show to us what she had done to Misato AND forced the woman to do to Sousuke in the motorhome. As for the SD card, Sousuke himself saw it, there's no reason to deny it as viewers.
If your point is that Shingo is lying, then it doesn't make sense anymore, he lost his audience, wig and will.
If it's that he was fooled by Rika and she used a double, it does not change that she had, at least, one video doing it with Shingo. Actually, it makes the scenario worse if it's Akito's sister, because the girl was seemingly coerced into this by Iwabuchi, and lent to Rika to do the deed.

Edit: another point that reminded us way earlier, is that Momonga focuses on adultery and the camera angles are POV. This type of content is still more common on these accounts, meaning, there wasn't much of a diferential, except for the public places, and those were quite recent. Meaning: still more difficult to increase SNS engagement and grow as as account using organic traffic alone.
