O-oh... she's actually deeper than we thought. No one expected she's the dark version of Sumire.
EDIT: There is a non-zero chance Sumire is related to Ruri. Sumire's eye and hair colors are extremely similar to the Konno sisters though, but it's still not impossible she could be related to Ruri.
Ruri actually is, or was, taking her escorting seriously as a big sister.
A culture might've developed that older sisters are supposed to look after their younger brothers.
From what we know, moms usually stop having kids after they have a son.
The son gets special treatment, but as we've now seen, it varies from mother to mother.
Satou Akane loves her daughters even if she already has a son, but Ruri's mom probably ignores, if not abuses her.
The horrible part of this is that it actually makes sense for them to ignore their daughters in favor of their son with how skewed the sex ratio is...
It seems being traumatized, for obvious reasons, makes women more resistant to falling to their "female instincts", though we can see Hinata's trauma being healed bit by bit.
I actually don't want Ruri to fall for Sou or even the boy she's guarding. I much prefer now that she builds a friend or sibling dynamic with the boys. I feel like genuine friendship between men and women in this world is even rarer than men just banging women (looks at R18 Sou, although he is friends with them... with benefits).
And if you guys want it even darker... consider if one of those crazy females birth a son, and the fact that incest is, I assume from this and the R18 world, is widely-accepted.
EDIT: Someone caught on that Hinata is gripping her hand tightly. So that's at least two women with family issues...
God I unironically love this series. There's the funny parts of course, and then it sometimes hits you with the ramifications of this world. Also I want to take this opportunity to shit on Solo Levelling again. Somehow the worldbuilding and characters in that are shallower than this one lmao.
Say, how do you guys usually refer to this series? Danjo-hi? Or A Parallel World With a 1:39 Male to Female Ratio (a bit long IMO)? I think referring it (partly) using its Japanese name is an issue since a lot of them also has "danjo-hi" in the title. Maybe "Danjo-hi 1:39"?
