Danjo-hi 1:39 no Heikou Sekai wa Omoi no Hoka Futsuu - Ch. 299 - Kurose Ruri Saw It!

[Kurusou]

In the R18 world, Yuri-can-sama is the first outside the family who had sex with Sou in his bedroom .

And you're right about Kanaria.


If the colored version is accurate, it's possible for Sumire and the Konno sisters to have the same father/donor. They kind of look alike and they have the same eyes and hair color.

I have also the same feeling with Sakura and Hinata, somehow they share the same vibes but maybe it's just me.

But the issue is, it's a fan colored, and I don't remember Kisa-sensei to confirm this theory.

now you think of it makes sense that they have the same paternal donor

Color version is accurate. The color version is based on profiles provided and R18 version provided by Author.

Now I want to know what's the probability of any two women in that world having the same sperm donor. I hope someone smarter than me comes along and figures it out.

That is alluded by Author in chapter 201. Misaki-chan remarked that herself that it happens.

[sh1thappens]

I think Kurose will be flashbanged by Sou next chapter

then banged surely

 

[Sengil]

Yuri-chan deserves all the praise. Love how all three women of the Sou-family put their trust into her on top of that. No wonder the poor girl is shaking, lol. That was an exhausting day. Honestly, she deserves some reward from Sou-kun after school.
And from now on the guard students will keep Yuri-chan in mind, the most dangerous not-guard student in school. XD

 

[Phantasmoon]

It completely went over my head until now, the fact that there is a non-zero chance one or more of the girls in his class might actually have a child with Sou through the sperm bank. I mean there's even hints that Sou's sisters might have the same father as some of his schoolmates already.

Though I presume nobody will ever know. I don't think it has ever been said if the donor father or mothers know anything about each other. But in a world where men need up to 3 bodyguards just to step out of the house, I doubt there's any info exchanged.

Huh, I wonder if it could be done through mutual agreement. I wonder how non-R18 Sou would handle such a request from his classmates. Actually, I wonder what he thinks at all about the idea that people he knows could be getting his donation....he doesn't seem to have thought about it either, like me.

That is, if the recepcionist let enough for someone to be bred, I mean, she loves to take zips of that cup

Now I want to know what's the probability of any two women in that world having the same sperm donor. I hope someone smarter than me comes along and figures it out.

We have the ratio, but it's still depend of the number of sperm donor in a city and their semen's quality, because some donors may have a better sperm count than the others men. Also, we need to consider the average age of the inhabitants and the total fertility rate.

For the males population, we need to substract the boys under 16 and men with a low sperm count or infertile (see chapter 19), and elders if they hit andropause or the sperm quality drop drastically. So arbitrarly, we can assume only half of them are in capacity to be a donor.

In the end, the less donor there are, the higher the chances for children from different mother to share the same father.

Besides, in this world, men gave their sperm once a month (chapter 19), so 12 times a year minimum but they can do it once week at most (chapter 28) for a maximum of 52 times a year which increase the chances further if the difference in sperm quality or the number of sperm donation between donors differ greatly.

Dunno, if I'm clear because I've spent too much time to write this and it gave me a headache

Edit : I've forgotten to say, if the number of donors stays the same then the more children different women have, the more chances they have to share the same father. Example, if two women have 1 child each, the probability is low but if they have 3 each, then the probability increase a little. Now imagine 10 donors with the same sperm quality for 390 mothers who end with 3 children each

 

[Evidenox]

Ruri doesn't know about Maria's illness I guess.

Gentlemen, ruri is a car before a car crash. She nows gonna speed along the school and hit a concrete wall known as Satou Sou.

More like The Titanic, I know the iceberg is coming, you know the iceberg is coming, but the ones on the ship don't.

Poor Yoshida, he doesn't deserve to be talked that badly. If he finds out he'll crash out, then girls complains why guys despise them in that world.

I hope Satou-kun adopts him and we get a senpai-kouhai dynamic (of course, Satou being oblivious Yoshima sees him as an alfa).

I think if they meet Yoshida will definitely develop a crush on Sou. Even Suzuki is veering dangeously close to "I have to protect him!"

 

[Nehona]

On a completely unrelated note, we know that Suzuki has at least one older sister. I want her as a character...

Imagine Suzuki seeing his sister drooling over Sou. It would be priceless.

 

[AIt3r]

Oh yeah, ruri might tell the family about the locker incident with yuri

Now I want to know what's the probability of any two women in that world having the same sperm donor. I hope someone smarter than me comes along and figures it out.

I don't know how to calculate the probability, but there are a lot of factors:

• The "donations" are mandatory and every month, and most men in this world only give the minimum amount.
  • Sou gives more per session, and goes every week.
  • We have no info if married men still need to donate.
• A single donation can theoretically make hundreds of women pregnant, but from my research each donation is split into 2-6 vials. Each one can be used to attempt pregnancy.
• But this world has something going on that makes the male/female ratio at 1:39...
  • Birth rates also seem to be lower than our world judging from all the sex R18 Sou is doing and only making one woman pregnant.
• The government has to spread one man's sperm around to keep half-incest to a minimum. In real life, apparently governments keep sperm use to 10-25 families at most to make this less likely.
  • But incest in this world seem to be socially acceptable, if not expected... which means the humans of this world are either desperate enough for men that they don't mind the massive health problems from incest, or they've actually evolved to be resistant to it.
• From the R18 universe, we learn that most mothers stop having babies when they birth a son.
• Unless the situation is dire (and a 1:39 world is extremely bad as it is), I don't think governments ship sperm to other countries.
• With the massive shortage of men, that means most people in this world are born from donations.

With all these facts in mind... it would make sense to spread a donator's sperm in more locations for genetic diversity, but the society also don't mind incest so I'm not sure if they'd follow that.

This makes half-siblings more likely in one location if they don't have a maximum amount of families for each donator.

Most people are born from donations so... that makes it more likely to run into a half-sibling without one knowing.

Also on an unrelated tangent: I think Hinata is the only one in the series so far that we know who was born "naturally". Maybe that played a factor in her being easier to get pregnant...

 

[DLRevan]

If the colored version is accurate, it's possible for Sumire and the Konno sisters to have the same father/donor. They kind of look alike and they have the same eyes and hair color.

Sakura does say the Konno sisters have the same vibe as Sumire, and her friend pointed out they might be blood related through the donor bank. She then says it's not about that, but this was when I first thought about the possibility. It seems obvious that Kisa-sensei is at least deliberately hinting at it, regardless if it turns out to be true or not.

 

[DLRevan]

It's even worse than what you think. There's a non-zero chance a random woman who's pregnant with his child right NOW through Sou's sperm donations since he started doing them.

Well...of course. The point of the donations is so they would be used. I had no illusions about that.

I'm just pointing out it's a different story once it starts involving people he knows, and more importantly, people we know from the reader's POV. Rather than random people we will never get to see. That's more exciting and more room for tomfoolery.

As for why I still questioned the possibility that he could be informed to some degree of his offspring, do note that actually very little time has passed since the start of the story. I doubt such a system exists, but if it does, it may just be too early.

When you know men hates women in this world, I'm sure Married men are an endangered species. And with the shortage of men, you can't cut on ressources, so it's obvious they still need to donate.

Besides, chapter 19 we learn men over 16 with a normal sperm count must donate once a month, it's an obligation. The marital statut don't seem to be taken in account.

In chapter 6, Sou's mom said for her 3 children, she was inseminated with sperm from different donor, so it must be the same for other mothers with at least 2 children. Like you said, genetic diversity is important to avoid inbreeding.

But If incest is acceptable in this world, I suppose a child born form half siblings will be less worse than from true brother and sister

For this matter, I'm sure the goddess, who brings Sou the savior, used her powers so there will be no problem

 

[dimox]

but Yuri the Hero will never be forgotten!

don't put up her tombstone just yet

But hmm, but my author's instincts tells me she'll fall hard for Yoshida later, not Sou. At least I'd write it that way to be more interesting...

Hm, had it been me, Ruri would become dere but not completely, it would only ne with one person and it's neither Mairu or Sou because I would assign her to Suzuki - like, literally:

Ruri becomes Tooru's guard team lead after a class shuffle mixing up the entire grade. She first tries her usual shit but fails to treat him like Mairu - Tooru doesn't care and her new second in command would be someone from Class B who disapproves of that behavior. Not to forget the third guard, namely Hinata, much to Tooru's horror. What a team. Ruri will later realize she could have gotten a way worse assignment since her "new guy" is not clingy (Mairu), unbearable idiot like Yamada or an irritating and dangerous fellow like Sou. Ruri starts taking her job seriously.
Tooru slowly becomes more relaxed with girls in his class. Then, during an event down the road, he'll end up completely alone with Ruri and does something that changes her view on him completely (he prevents her getting expelled). A serious talk later both begin to understand and later actually trust each other unconditionally. Now please imagine the utter disbelief when Tooru first calls out to her with a simple "Ru?" to interrupt her constant bickering with Hinata. It got him the nickname "Snake Charmer", which actually bothers both of them.
After graduation Ruri remains at his side as his exclusive guard wife. Both would end up working for Konoe Academy - Tooru will be a "poster guy" as a successful alumni and draw in new male students, and he'll also function as a counselor in male-only affairs. Ruri protects him on school grounds and works as guard team advisor.

Something like that... if only I could draw, I would love to do some what-ifs.

 

[CyanHide]

Oh no, the landmine girl is turning into a heat seeking missile

 

[Kaito57]

Ooooooh, Ruri... sweet sweet foolish Ruri... looks like you still need to LEEEEEAAAARN !!!!

This is the story of modern day Genghis Khan.

I keep saying it : Sou is basically a freaking SCP in this world !!
If left unchecked, soon, most of the next generation of Japan alone will be related to him lol

This girl need some CORRECTION to be done immediately 💢💢💢
