Well, it's definitely been a while since I've played a game from this particular circle...
First of all, I've played the version uploaded on the 2nd of May 2024, and I have no idea what the version(s) before it were like. This version is still done with MTL, but you can tell that there's been quite a bit of effort put in to make it understandable. There's still some MTL stuff here and there, but not nearly as terrible as it could be. No idea what's up with paco-paco btw...
ANYway, the game is fully understandable, and more importantly, all the tutorials are clearly translated, so you can easily understand what you need to do at any given time, etc. The only thing that has some very obvious issues are the chat comments... but, well, those are always gonna have issues because of the difference between Japanese and English. You'd need to outright re-work the UI to fix that, which goes beyond the scope of even professional translations for the most part. Especially with the size limits of this particular RPGM engine.
Beyond that, there's not much of a story. Girl's family inherits debt from deadbeat runaway father. Yakuza rolls in on them to collect. They put them all to work in various ways with the express goals of turning them into prostitutes. Chisato, the girl in question, is made to be a "Chat lady", and of course, the chat in question is lewd with the possibility of becoming lewder. Things start pretty tame with flashing tits or panties, and then escalate more and more. After that, each day is split into a day phase and a night phase, with weekdays requiring Chisato to go to school.
On top of that, the other girls, her sister and her mother, are also supposedly working in other places, and there's also an Interest mechanic, which, if not paid, causes conditions to worsen for the girls in question which leads to various forms of depravity happening to the two of them. Now, I'm confused why they don't just use the hypnosis app on all three from the get go... Internal consistency is not great in this game.
In any case, you don't need too, strictly speaking, have Chisato slut around beyond the Pink Chat, because income will steadily increase with viewers and popularity and whatnot... but her lewdness stat will increase eventually unless you skip school all the time. Why? Because there's a discovery stat which increases constantly, and when it reaches 100%, Chisato gets raped at school. This happens several times, and all of them increase the lewdness stat. Requests also result in her getting fucked and with lewdness increases. In general, all the stuff that gets more money leads to Chisato getting fucked. Obviously.
This is... not much of a big deal though, because the lewdness value doesn't do much of anything besides increasing the amount of things Chisato can do and some of her reactions on the various streams. Her behavior doesn't change much and it also doesn't seem to affect the ending in any way on its own. Same thing for the bad-girl value thing, which only unlocks actions and whatnot, but doesn't seem to seriously affect anything aside from the possibility of causing a scandal to happen and that requires specific actions. I haven't really bothered checking in depth.
Either way, I got "Ending A - A family Reunited", which seems to imply that there's multiple endings, but from checking the gallery, it seems like those ending variants depend primarily on what happens to the other girls, more than anything that happens to Chisato. Even if Chisato has lewdness 100 or high bad girl value or anything of the sort, nothing happens to the ending. Even the fact that she will basically become the school slut doesn't seem to change anything. (There's no real way to avoid this, as far as I'm aware, because you have no means of preventing the discovery value from growing, much less making it decrease. You can skip school I suppose, but that should have its own consequences... and that doesn't happen either. Not to mention that you won't get the Quick Stream stuff, not that the Quick Stream stuff is particularly useful...)
So eh, the game is... pretty silly and not that well thought-out for the most part... but at least the art, animations and H-scenes themselves are pretty on point. So overall a pretty decent game. Not an amazing one, not a great one, but decent. Definitely worth the time, and likely the money if you can afford to throw said money at the maker of the game.
