Let's quote it again, if it helps:
"When I was a student, I worked in cabaret clubs and escort cafes, and when I first started working, I did paid drinking. I decided to draw on those experiences to create a manga about working in the night industry."
"The model for Mii-chan is a girl I used to work with at a cabaret club in Kabukicho. She was really bad at kanji, to the point where she couldn't even read the menu at an izakaya. She said she had a mild intellectual disability, and she even had a disability certificate.
"While he treats even the most 'bad customer' with a smile, he also has many weaknesses. He even reveals his real name and address right away, and there have been times when regular customers have become stalkers."

In addition to talking about her own experiences and those around her, Atsuki also makes sure to go out and talk to women in need.
"Recently, I've been talking to the girls at Toh Yoko to get ideas. The girls at Toh Yoko can seem a little hard to approach at first glance, but some of them are surprisingly friendly and tell me their stories when you talk to them."
"Toyoko" refers to the square next to Toho Cinemas in Kabukicho, Tokyo. Children and young people who have no place to go at home or school gather here.
In December 2023, the Metropolitan Police Department conducted a sweep in the area, taking 28 people into custody, both male and female, between the ages of 12 and 19. Among them was a sixth-grade girl.
(If you've played any of the earlier Yakuza games, this place is in there - AFAIK the big cinema in Kamurocho is basically almost directly drawn from how Toho Cinemas used to look.)
This is direct MTL from the interview she did with Japanese MSN, before this version of the manga started running. So yeah, while the manga is definitely "
based on true events" (i.e. and
not "every single thing in here happened exactly as it is shown to have happened"), I'd say it certainly seems to be drawn pretty heavily from life, and she seems to have been putting in some effort to make sure it stays that way.
And like I put in the notes, more than once I'd go looking for old articles about various issues this chapter or that chapter brings up, thinking "What was it like back in 2012?" and find out "Oh. It's still like that
now." I didn't want to stick a load of URLs and quotes in there because I'm not writing an essay and I'm guessing there's not many people reading this (...yet?) who care, but for example with this chapter, if you search for "news articles japan "okubo park" ", you'll easily get plenty from the past two years rather than a decade ago.
The next chapter gets a bit less grim, although the not-grim stuff mostly happens to Somebody Else (the manga introduces more characters than just Yamada and Mii-chan). Part of that is directly looking at how somebody in her position got processed by the system back then.
