Ecchi Myth Busting (#1) – The Keijo Nipple Toss!

A little while ago Keijo!!!!!!!! (Episode 9), Lynn and I had a chat regarding the nipple toss that we witnessed in the episode:

“That’s not very realistic now is it?”
– Lynn

“True, it doesn’t seem very realistic.
But I wonder if it’s in any way possible?”
– Yomu

“Have you lost your marbles?”
– Lynn

And so here we are.

It’s time to take a look at this crazy ecchi scenario and determine once and for all if it’s even remotely plausible! For science, and peace of mind.

Just How Realistic is the Nipple Toss from Keijo Episode 9?

First off, to save you the trouble, here are the images of the nipple toss in action:

As you can see, Miyata uses a single erect nipple to hook her opponents bikini top, pulling her opponent towards her body and then using that momentum to toss her to the ground all in one fluid and brutal motion.

I’ve identified several aspects of the toss for us to look at and examine individually:

  • Nipple erectness
  • Nipple weight capacity
  • Bikini top strength

While Miyata using her back to shoulder the weight of her opponent seems plausible as is, the act of physically getting her opponent to that stage, as well as the release seem questionable. Would it be possible for Miyata to use only a single nipple to accomplish all of this?

Nipple Erectness

Can an erect nipple hook onto and maintain it’s hold on an object?
Specifically in this case, a swimsuit?

In order to test this, I needed to gather some willing volunteers in order to test the hooking ability of an erect nipple. And so I put out a request to the community asking for volunteers, both in English and in Japanese, because I am in Japan after all.

Unfortunately, I’m still awaiting on a response.

Realistically we can logically look at this and figure that there’s just no way a nipple could both hook onto a bikini top and maneuver the way Miyata managed to all on the strength of an erect nipple.

However, I’m going to pose an extreme here.
What if Miyata’s nipple actually got caught in the bikini top?

For example, what if somehow her nipple somehow got tied up in the bikini top? Or there was a small hole in the bikini top that her nipple fit through? Or the nipple actually poked a brand new hole through the bikini top?

At the end of the day, while I think the way the anime presents it is unlikely, theoretically speaking, there are ways in which a nipple could get caught and / or stuck in a bikini top.

Theoretically, there are ways in which I could get stuck in one too…

Nipple Weight Capacity

Luckily, we can move on ahead and test the next area of concern in this myth: the weight capacity of a nipple. And unlike the previous section, this one we have some answers for. Reason being, apparently there are some real kinky people out there, and so “nipple weights” are actually a thing.

And so, with my sources omitted, I managed to figure out that the heaviest nipple weights out there seem to be around 2 pounds (0.9 kg). I read that any heavier than that can cause damage, and even then, 2 pounds is on the heavy side. The average weights seem to be around half that, at 1 pound (0.45 kg).

What this means is that even if Miyata’s opponent was a baby, the average human baby weighs between 5 pounds (2.26 kg) and 8 pounds (3.6 kg). Even if Miyata was to use BOTH of her nipples, she still may not even be able to lift a baby, let alone a grown woman!

But we’re not done yet, because if you examine the scene in question, Miyata never actually has to bear the full weight of her opponent! Miyata first hooks her opponent, pulls her in, then using her back propels her opponent forward. Meaning that while her nipple would certainly bear some weight, much of the weight is actually borne by Miyata’s back.

In addition, we aren’t done yet with the strength, because nipple weights are an object people wear for… pleasure… (I won’t question it). In reality, skin is a lot stronger than that. In fact, this study measures a tensile strength of 27 Megapascal, which is 3916 pound-force per square inch, or 270 bar!

What this means is that in theory, if Miyata’s nipple managed to really grip that bikini top, it could probably pull off this crazy maneuver! Although I’m sure that her nipple and the nerve endings in it may end up damaged as a result.

Bikini Top Strength

Thanks to modern science and the internet, I was able to come across information to help us here as well. This time, I will source my findings.

First up are the materials commonly used in swimsuits, which are typically either nylon blends or polyester blends. And then with that, we can look for the fabric strength. If we take the extreme from the fabric strength tests, we can see that a strap of 1680D Nylon/PU has a whopping strength of 475.8 Newton, which is 107 pounds (48.5 kg)!

While we can’t perfectly extrapolate that to a bikini top, due to differences in thickness and whatnot, for the purposes of this myth I think it’s fair to take the extreme here and argue that Miyata’s opponent COULD HAVE been wearing a durable bikini top made of 1680D Nylon/PU, or perhaps an even stronger fabric blend. And when you consider that the average Japanese woman’s weight is 116.6 pounds (52.8 kg), this is looking somewhat plausible!

In Conclusion…

With all of the data considered, I’m feeling confident enough to say that this myth is actually plausible!

Of the three key aspects of the toss, the only area that seems truly implausible is the ability for a nipple to hook onto the bikini top itself. But even then, if we look at the extreme situation of the nipple somehow getting tied up into the bikini top or somehow caught in it, the toss itself begins to seem theoretically plausible due to the fact that both human skin as well as the potential bikini top material are both theoretically strong enough to shoulder the weight behind the toss.

So while I went into this having my own doubts, in fact, in the absolute extreme situation, in my opinion, it actually seems theoretically possible! That’s right Lynn, I’ve still got my marbles!

And on that bombshell, we can now all rest easy knowing that one of ecchi’s biggest mysteries has been solved, at least somewhat.

Were you as surprised as we were?
Did Yomu fail to consider anything important?
