I said I was preparing for the serialization, but here I am drawing a wall butt.

Everyone must have gotten soaking wet from the sudden thunderstorm.

I think that even if the crucial scene was captured, it probably couldn’t be distinguished.

It was a nice story…

The wall butt sister’s incontinence is quite fetishistic…

What Otae-san said in Gintama about true friends is that you should wet yourself together, and it wasn’t wrong…

If you pee, it means the world will collapse.

The development where the initially incompetent glasses teacher becomes irrelevant was something else…

The author is really good at storytelling.

>>14

The balance is too bad… or is it actually efficient?

>>18

Isn’t this a party for gathering materials?

>>145

What the hell is that guy?!

Masakazu Ishiguro?

Throwing away all the characters with a story presence like the incompetent teacher, sister, friend, brother, and the hero-like person to ramp up sisterly love is too destructive.

>>20

Is it about pee?

I wanted to see my grown-up sister too.

>>22

Isn’t the one who came out at the end your younger sister, not your older sister?

It feels strange to have both a sense of chaos and a sense of coherence.

This person seems to be the type who can output strange things even when asked for something structured in terms of worldview or naming.

Aside from highlights, I feel more discomfort than enjoyment when reading short stories that can be categorized as mere embellishments.

If you are going to write a long work next, I would like you to try it with an original work.

>>25

This short story had many rough parts and was quite difficult to read…

I understand what you’re trying to say, but…

>>25

I think that even if you add an original story, it won’t become interesting because the strength lies in the ability to create short stories.

I think it’s a bit lacking for a doctor to write this with their butt facing forward.

>>27

But I’m an adult with enough sense not to let scenes of girls urinating be shown on TV…

>>27

But you prevented the nationwide broadcast of my pee, didn’t you?

What is this erotic manga that only lacks a real performance?

I wanted to see something like this.

Scientific supervision: None

But thinking about how my sister was wetting herself nationwide for her little sister at that point is tempting.

The hero is too splendid.

Jump Plus Today’s One-Shot

>>39

Sexual Preference Expo

As the doctor says, people have a heart.

But that aside, my crotch is yearning to look towards the original world.

>>42

I can’t help but want to see the underwear and skirt get all messy as the urine seeps out, and I’m academically curious whether it just drips down the thighs or if it comes out vigorously, sewing through the gaps in the fabric.

>>44

Sister of the surveillance class!

I thought it would be a showcase of fetishes, and it turned out to be a showcase of fetishes.

I’m definitely more suited to being an author!

The doctor and the hero… what impressive guys they are…

But if I keep this level of excitement in the serialization, I’ll end up like Bobobo.

I feel the experience points of “mama yuu yuu” in the depiction of another world.

I heard that you drew a realistic style using GIGA.

I’m very happy to see that you’re not throwing away the original style.

Thanks to the weekly serialization, my drawing skills have improved a lot.

Did you need a hero?

>>54

If there is no one to give water, the world won’t collapse due to urine.

>>70

If it doesn’t lead to the recovery of the sisterly relationship, it would be too much of a reverse MVP…

This is exactly what I wanted to read.

I remembered the game devil because of the amazing professor.

I wonder which issue of GIGA the post-Mamayuu serialization is in.

>>59

Winter 2025

The newest one.

I don’t really care, but I noticed that “San!!” is used even when you’re alone.

If it’s going to be a series, I’d prefer it to be a one-episode format, but if I have to draw something like this every week, it’ll fall apart quickly…

I was surprised that the comment section on Jump Plus was in chaos, even though it was interesting.

Things like this usually get a good response.

>>63

They immediately get defensive about sexual exploitation and such over there.

>>75

Isn’t it a bit too much to react only to the image in the thread without seeing the bigger picture…?

>>80

When it becomes a hot topic in the media, those kinds of people tend to jump right in.

>>63

Aren’t you looking at a different comment section? I think it’s being received normally.

Hey!!! What are you doing breaking the camera!! We have the rights to broadcast here!

I wondered what my first teacher was… but since they don’t come up again in school, it’s fine.

It’s nice to slip in a gag without making a fuss about it.

Thank you, doctor…

You’re a good guy…

I want to become a man as accomplished as a hero…

Maybe I’m only using about 30% of my intelligence while drawing this, compared to other one-shots or series.

>>72

No way… even though such an intelligent character is appearing…

All elements of another world

It must be an existence for my sister’s “end of the world.”

I thought it would be a worldwide live broadcast of the sister’s pee, but thanks to the light scientist, we were saved.

The vibe was very good, just like a stick figure’s.

Please publish a short story collection.

In the comment section, there seem to be two types of people: those who react to the word “wall butt” and those who do not understand that the portrayal of the stoic genius is a joke.

Coating wall butt peeing with sisterly love…

Yuri sisters wall butt urination is a genre I’ve never heard of even at SOD.

>>85

Surely, the AV director of light is stopping by breaking the camera.

>>86

You are the darkness, aren’t you?

It seems that suggestive topics no longer appeal to the general public in this day and age.

Just like the violent heroines and violent gags were exterminated…

>>88

I think it’s been like that since the time of Hanreki Gakuen, so you don’t need to worry about it.

>>88

It seems like a manga that is trying its best to turn a story about JS and JK’s wall pee, which can only be found on DLsite, into a gag.

If this were an erotic manga, it would depict trashy citizens grinning while pointing their phones at their butts.

The doctor and the hero brought out a good flavor.

>>91

It’s okay to hold back from pooping while urinating rationally, so that diarrhea doesn’t come out at the same time, and even continue to hold back from diarrhea afterwards!

Why can you easily create a device that allows for interdimensional conversation on the spot…?

>>92

Isn’t Maxwell’s theorem being Schrödingered in the theory of relativity?

>>92

It’s an incredible doctor, you know?

Since there is already a hole… it seems like it might work out somehow.

Is it because you’re a genius?

“Until the yuri sisters wet themselves, it’s real, right?”

>>100

The lines are overly emphasized as not being embarrassing at all, which is cute.

>>100

The expression of emotions that a normally stoic child suddenly shows is wonderful.

>>100

The lines being really panicky is good, isn’t it?

It’s not sexual, it’s fetish.

I thought the sisters’ pee became a thunderstorm that saved the world.

>>104

The hero may have crossed dimensions to make it rain.

If the hero suddenly says that they are unnecessary at the core of the story, wouldn’t it have been better if there were no isekai elements at all…?

>>108

I want you to think a little more about why the hero is no longer here.

>>108

If you remove “it’s good that I don’t have it,” you just end up being sisters who pee against the wall, which is not good.

>>112

That’s that…

>>108

Are you saying you don’t need the part about the world collapsing from your pee?

As always, the short stories are interesting.

I reread the track and field one after a long time, and it still makes me cry.

The main point is that I want to convey my feelings of wanting to help my important little sister, even if it means getting embarrassed; if I hold back, I might end up in an even more embarrassing situation.

If this were Young Jump, Magazine, or Young Champion, there wouldn’t be any complaints, but with Jump Plus, I can understand the sentiment that it’s natural to voice criticism.

The depiction of the fantasy characters starting to say clichéd things and the depiction of the sister and the doctor repeatedly spouting equations and theorems that seem fitting.

It must be equally incomprehensible conversation for my sister.

Well, it’s Jump Plus after all…

Sisterly bond is great…

The theory that if otherworldly urine and real-world urine intersect, it’s safe is too genius for me to understand.

Maybe it wasn’t necessary to bring up the word “wall butt.”

>>121

It would be necessary to create an impact for the title.

Was it really necessary to have a teacher who gets angry despite being wrong…?

>>122

I needed to write about my younger sister being rebellious, but it was important to frame it in a way that showed she wasn’t doing anything wrong.

It was so pointless that it was funny.

I might really love this author’s work.

It makes me feel strange, but I have a strong sense that I would end up drawing a manga that would be canceled even if I serialized it.

Isn’t there a number of even more vulgar manga than this in Jump Plus?

>>128

It’s pointless to worry about those who complain, as they even find something vulgar in a stain on the wall and get upset.

>>128

Are you talking about Unpidas Brueghelli?

There are elements that make me think, “Do we really need this…?” but I also feel like it would become boring if we got rid of them.

It was fun, so it’s okay to lose.

The media should work harder for freedom of the press.

>>130

No human heart.

I don’t dislike Mamayuuyuu, but there were a lot of elements that made me wonder if she’s really there.

I think it would have been more interesting if the focus had been solely on the mom and the hero, considering that the thread’s picture was entertaining when it zoomed in on the relationship between the older sister and the younger sister.

It’s still all messy as usual!

Sure, sure!!

Is it someone who was drawing stick figure people?

Do you need this? I’m creating a gag with a sense of pace.

>>136

Ordinary readers would implicitly understand that they tend to skip over a list of technical terms…

I mean, this person draws girls super cute in a simple way, doesn’t she?

>>139

I remembered that I liked the King of Twinkling Stars.

I liked the way of fighting too.

Isn’t it the case that, rather than the vulgarity, the part where the equation spamming fails to adjust the realism line due to the illustration style is what the reading cut maniacs are more focused on?

>>143

Even though I’m going to another world through my wall butt, does it matter if the reality line of the physics part is crap?

>>148

If you mistakenly think it’s a twisted SF one-shot, there’s quite often a pattern where that part is unnecessarily solid.

Ah, so I thought my sister was going to shove something up from below, but that wasn’t it.

>>144

I understand.

My sister’s lower half grows next to me, and we mutually pee on each other! Maintaining world balance! That’s what you would expect, right?

>>149

I thought so too, but if I push in from the legs, the skirt will flip and my sister will be completely exposed to another world.

>>155

So it shall be.

>>149

I wonder if they ignored that part to facilitate the dialogue drama.

>>157

I thought about it, and if urination in another world causes reality to collapse, then I think urinating with real-world matter would only cause the other world to collapse.

>>149

Doesn’t that mean the world collapses with little sister’s pee and the other world collapses with big sister’s pee?

>>163

The world is already starting to break down from the moment my little sister pees.

>>163

It seems that urine is breaking the balance from world A to B, so I wonder if they will add B to A to restore the balance.

>>177

I thought so, but it’s too surreal because there are no interactions between the sisters…

>>181

But there is a device that allows us to communicate across dimensions!

>>144

I thought it was a story about an older sister sticking something into her younger sister’s lower body hole.

I am someone who quietly leaves a comment saying it was funny when the comments were flowing with trash.

Scatter!!!

The doctor is an amazing person.

People… it’s the heart, isn’t it!!

So you’re saying it’s real to win the Nobel Prize every year and learn under the amazing Doctor Sugus starting next year?

Well, I think there might be people who feel resentment because the term “wall butt” has a straightforward erotic connotation.

I think it’s a good title because, even though it’s a silly one, it makes it clear how to read the work.

This is tempting…!

I think the equation rapid-fire section is in a good balance where those who are not familiar with it can just go with the flow, while those who are knowledgeable can understand the humor through the quantity.

Is this author into multidimensional fetishes?

Don’t bring that over here when we’re closing comments immediately to protect ourselves!

>>160

Everyone lacks the spirit of a hero…

I liked the story, but I think there are many parts that are lacking in refinement, such as the incomprehensible teacher mentioned above and the coffee section, so it feels like it’s almost there.

I understand the feeling of it being irritating even if you know it’s a joke when you’re just presented with a list of familiar words.

Reading this manga and then talking about the use of equations or whatever is not what a manga reader does…

It’s just that I think I’m smart…

>>164

It tempts me.

I thought it was a fetish expo, but it was actually a fetish expo.

I don’t really know why, but…

If we both wet ourselves, it will all come to a round conclusion.

This is fine.

The part about the coffee is probably why my older sister was able to go.

Realize that you win the Nobel Prize every year.

I feel embarrassed if people think I’m reading manga…

It felt like a story made from a three-part tale…

It’s human emotions, after all!!

Japanese version of Interstellar?

Regardless of the interpretation, I dislike manga reading a bit…

I also considered the possibility of the older sister directly drinking the younger sister’s pee, but this is Jump, after all…

The element of another world is just a tiny pinch, it’s laughable.

>>182

If anything, it feels like quite a few pages have been devoted to this…

>>190

Thief Thief Thief

“Well, it got a laugh.”

No contemplation is necessary in this situation—…!!

It’s nice to have fun together, but personally, I liked the part where they kept chanting “Holy Judgment Light!” while crying.

The hero is too much of a hero…

To weaken the effects of the urine from the younger sister, who consumed things from another world, they sprinkled the urine from the older sister, who only consumed things from reality, beforehand.

Don’t overthink it every year during the Nobel Prize.

I couldn’t help but laugh at how the conversation between the geniuses was surprisingly empty.

I vote for the idea that I just peed myself to avoid embarrassing my little sister.

In conclusion, it means that the intelligence of web readers is roughly equivalent to that of a second-year middle school student.

I feel like I’m consciously experimenting with the overwhelming amount of scattered information.

If we think of it in terms of roles like the doctor’s assistant, there’s probably less need to add more characters…

In the end, I think it’s a manga that’s ultimately about “my sister, the wall butt, and me.”

Isn’t it just diarrhea when your stomach gets loose?

It’s strange that there’s no rain at all when it’s supposed to suddenly rain as soon as I get home!

>>196

It was so wet that I mistakenly thought it was a flow of otherworldly pee.

Isn’t wall butt and urination, each on their own, not really erotic?

If your stomach is loose, I think it’s diarrhea. If you apply this based on the Fibonacci sequence to the theory of relativity…

I thought the name of the character that is too foolish was a bit excessive, but since there are those who still don’t get it despite all this effort, it’s difficult to consider the lower limits.

When I try to point out the strange depiction, it makes me think, “Is that really the place to criticize?” so my defense is strong.

Regarding the depiction of geniuses that seem foolishly abrasive, people… it’s about the heart, right!!!! That’s what makes it interesting and meaningful.

When I read it again, I just kept writing the digits of pi on the wall, and it was no good.
