I DON'T GET IT.

Okay... so I've decided to go ahead and read the OP manga 'cause I wanna see how Luffy's new form looks and already I am so confused on some things, and ticked off on others. I mean, I've never been a huge Oda fan for how he treats women in his series, but I've never thought he was bad at what he does. But--

Spoilers:

Queens head shooting off to coil around Sanji? Really? Yeah, he's a cyborg but I call bull on this one. Even if Franky can shoot his arm off, it's still attached by a chain and it just means his arms are entirely mechanical. Queen's form still has biological parts and I'm sorry, but a Brachiosaur's TRUE POWER is NOT to shoot its head and neck off like a boa constrictor. This is just stupid. He could have achieved the same effect by wrapping a cybernetically-lengthened tail around Sanji, or even his neck (still attached to the body). This was just... stupid.

2. I can't even tell what is happening in half the scenes. The art used to be much clearer. I respect that there's a lot of characters and major damage being done but when I have to blow up the screen to 200% to figure out what the hell is happening (and I still can't tell half the time) then there's something off.

3. Kin'emon being bifurcated and still alive. Okay, fine, it was the Strawhats who pout him back together and not Law, but you're telling me he's felt no difference since then? That Law himself wouldn't notice that Kin'emon was still just loosely connected? Despite traveling with him and fighting with him all this time? Law is known for being observant and a skillful doctor - that's lazy writing, Oda. And if this is all true, then why is he bleeding? (don't even get me started on the stupidity that is the talking through his ass - I thought this was stupid on Punk Hazard and it is still stupid today)

4. Aging Momonosuke. Interesting effect of the ripe ripe fruit but with Oda's perverted mind, he just stuck a child who likes to cling to women's breasts into the body of an adult male. Guess what is going to happen and I haven't even reached the Luffy's Nikka form yet. Oda, you're starting to get predictable with your misogyny.

5. What exactly did Kidd and Law do to Big MOM? Kroom? Magnetizing Big Mom? Really? How? What is the logic, the rationale, the physics (anime or otherwise) behind this? I'll accept it if someone can explain it to me, right now I'm just reading the panels, trying to decipher the art, and going, WTF? Assign fields of magnetism? What does this even mean? Seriously, I'm an old-school X-men comic reader and while Magneto could create and control magnetic fields, I have no recollection of him assigning magnetic fields to something, otherwise all the plastic weaponry brought to bear against him would be made useless (Plastic? Nope - I magnetize you! Abra kadabra!).

It's a stretch but.. is their some kind of metal or mineral, or metal-derivitive that exists in the human body that he could only access with Law's help? SERIOUSLY, I'll even accept that. Just... not out of thin air, Oda. There has to be SOMETHING plausible, otherwise there's no point in really caring what happens because ANYTHING can and literally will happen regardless of what we know from your own canon. If I can't attatch it to something tangible - some obscure science, an old Japanese legend, SOMETHING - then the quality of writing drops completely. I am a stupid person so please, if anyone can explain what happened in a semi-logical way, I'd greatly appreciate it.

Now for the things I like:

Yamato!!!!!!!!!! Has!!! A DOG FORM!!!!!!!!!!! This is my new favorite fruit! He's a white wolf!!!!!!!!!!!!!! Fuck I love Yamato.

Sanji turning evil? Mwahahahaha, I doubt it will happen but I like the thought of Sanji becoming a bit less emotional - maybe it'll cut down on his perverse behaviour but judging by that scene in the hot springs making its way around tumblr, I sincerely doubt it.

O-Tama is awesome but umm... has anyone actually thought about the after effects of her powers? O-tama is effectively the new Sugar - she has a horde of people now slaves to her (unless someone knocks her out??) and has completely taken away their autonomy and free will. While the Beast Pirates aren't exactly sympathetic characters, this is still something I can't see Luffy supporting once everything calms down.

There has to be a way to release them otherwise, seriously. Sugar. She's the new Sugar, and twenty years from now there will be another uprising from people trying to free their old comrades from her brain-washing clutches. There is a lot of scope for potential villainy here for fanfic writers....

EDIT: Okay, just read chapter, apparently effects last a month or longer if they want? How do they know if they *want* to stay with O-Tama? The 1-month effect is a good thing, but I am confused about the optional part.

Momonosuke's whining continues to get on my nerves. Yes, I know he's a kid. I *know*. But fuck if I can stand whining by kids in RL either so I have very little sympathy for a fictional character. You wanted to grow up quick, Momo, you got it (poor Shinobu. I don't particularly care for her as a character after she tried to advocate for the death of the Heart Pirates but she was forced by her future shogun against her will to use her powers in a way that benefited Momo in that moment but is going to have long-lasting mental consequences [well, if Oda decides to actually acknowledge mental health like he never has before] and she has to live with that). Stop whining!!!! BUT! I do like that his dragon form is similar to Kaido's except he IS a dragon and not the ....koi? Carp? Thing that Kaido has told everyone is a dragon. The future shogun of Wano with a dragon form? Very cool.

I KNEW IT. I KNEW IT. I've been headcanonning that Zoro is a descendant of Ryuma ever since Thriller Bark!!!! I've been headcanoning that Zoro was a descendant of Wano since we learned Wano was a thing! Gyukimaru! You tried to kill your master's.... grandchild? Possibly niece/nephew? How old was what's-his-face when he died and Gyukimaru began defending the Wano graves by himself? We know it's been twenty years of collecting swords (well, almost 20, how old was Hiyori when she left Kowamatsu?) I cannot WAIT for this to be made a fact in the narrative and the people of Wano realize that Ryuuma's successor is one of Wano's protectors!

Kakashi & Da Boyz: Lab Updates

Introduction

Approximately two years ago, I wrote this pairing lab report which compared Kakashi’s manga interactions with his top five AO3 pairings (excluding sensei/student and original character pairings). Since the numbers have shifted a lot for AO3, here’s what they look like in 2020. 

Materials

2018 Lab Report Data

A vague understanding of how math works 

A slowly dwindling grip on my own life

Methods 

See prior work for methods on manga interaction count as published in Keepyourpantsongohan, 2018. 

It is worth nothing in this section why AO3 was chosen rather than FF.net or any other fanfiction website as a point of comparison: AO3 has the ability to filter character relationships by romantic pairings. While FF.net has developed this filter in recent years, its history and use is much more sporadic and would be unlikely to produce a representative sample. 

Data

See prior work for raw data of manga interactions as published in Keepyourpantsongohan, 2018. Only total interactions are included as a comparison point. 

Total Interactions with Kakashi 

Iruka: 4

Obito: 37

*Obito’s interactions with Kakashi under an assumed identity as Tobi: 11

*Total (if including Tobi): 48

Gai: 50

Yamato: 29

Itachi: 6

Total Number of Interactions for Any Pairings Listed Above: 126

*Total: If including Tobi: 137

AO3 Pairing Story Count (as of 08-June-2020)

Hatake Kakashi/Umino Iruka: 3,453

Hatake Kakashi/Uchiha Obito: 1,808

Hatake Kakashi/Maito Gai: 888

Hatake Kakashi/Yamato | Tenzou: 669

Hatake Kakashi/Uchiha Itachi: 151

Total Number of AO3 Stories for Any Pairings Listed Above: 6,969

Analysis 

Figure 1: All Pairing Interactions by Percentage (exc. Tobi) 

Figure 1 Numbers:

Iruka: 3.2%

Obito: 29.3%

Gai: 39.7%

Yamato: 23.0%

Itachi: 4.8%

Figure 2: All Pairing Interactions by Percentage (inc. Tobi)

Figure 2 Numbers:

Iruka: 2.9%

Obito: 35.0%

Gai: 36.5%

Yamato: 21.2%

Itachi: 4.4%

Figure 3: AO3 Pairing Stories by Percentage (as of 08-June-2020)

(Note: Figures 2 and 3 marginally exceed 100% in order to both round and maintain the same degree of accuracy as the previous chart. For Figure 3, all figures will be rounded down to control the excess of 100%.)

Figure 3 Numbers:

Iruka: 49.5% = ~49.0%

Obito: 29.5% = ~29.0%

Gai: 12.7% = ~12.0%

Yamato: 9.6% = ~9.0%

Itachi: 2.2% = ~2.0%

Percentage Difference from Manga Interactions (Fig. 1 Numbers) to AO3 (Fig. 3 Numbers raw data)

Iruka: +46.3%

Obito: +0.2% (or Fig. 2 inc. Tobi: -5.5%)

Gai: -27.0%

Yamato: -13.6%

Itachi: 2.6%

Figure 4: Annual Rate of Growth in Fics from Aug 2018 to June 2020

Overall Increase in Fics on AO3 Since 2018 (Npast - Npresent)

Iruka: 3,453 - 2,298 = 1,155

Obito: 1,808 -  667 = 1,141

Gai: 888 - 391 = 497

Yamato: 669 - 371 = 298

Itachi: 151 - 111 = 40

Annual Rate of Growth (((Npresent - Npast) / Npast x 100) / Number of years) 

Iruka: ((1,155) / 2,298 x 100) / 2 years = 25.1%

Obito: ((1,141) / 667 x 100) / 2 years = 85.5% 

Gai: ((497) / 391 x 100) / 2 years = 63.5%

Yamato: ((298) / 371 x 100) / 2 years = 40.1%

Itachi: ((40) / 111 x 100) / 2 years = 18.0%

Conclusion

As compared to the 2018 analysis, Iruka, Obito and Gai all got closer to proportionally matching up with their manga interactions, though this is most significant for Obito, who is nearly on par with his manga interaction percentages. In other words, Obito is almost exactly as popular as you might expect him to be based on number of chapter appearances interacting with Kakashi. The annual rate of growth for Obito (85.5%) is also by far the highest. I would be curious to know what factors made this increase so high. 

Iruka, like in 2018, is most prevalent as a pairing, and furthest from manga parity (in the positive direction). It is worth noting that the pairing no longer represents the majority in Kakashi’s top five pairings, going from representing 56.7% of fics, to 49.5% of fics. This seems to be a consequence of the rate of growth, because while there were the largest number of fics for Iruka in the past two years (1,155), there was also the second lowest annual growth rate at 25.1%. Even so, the raw numbers do speak to the popularity!

Gai has moved slightly closer to manga parity, with a 2.5% increase in representation. However, the pairing still experiences the largest percentage decrease in presence from manga to AO3. Still, the rate of growth for Gai is significant, being the second highest at 63.5%.

Yamato moved slightly farther away from manga parity, but only by a difference of 0.3%, which means the pairing has more less maintained the same level of popularity as two years ago. The rate of growth is middling, not anywhere near as high as Obito or Gai, but significantly higher than Iruka or Itachi. 

Itachi was as almost close to manga parity as possible in 2018, so the pairing will likely only get further away with more fics being written. But as there have been such a small amount written (20 per year) it would be a slow increase in discrepancy. 

Having acquainted myself with the commentary on the prior report, it might be theorized that “attractiveness” is a factor in popularity of character ships. However, this premise is flawed, because in my experience as a reader, the act of loving a character makes them handsome. See: The Once-ler phenomenon, as described by Ed Helms on Funny or Die (Fealasy 2012):

“I heard there are people who have a sexual predilection for my character in the Lorax [...] And that is very odd, because he’s not a real person. I do agree, however, that he’s extremely sexy. But I don’t condone sexual fantasy about the Once-ler. I don’t condone it.”

So in this case, we can assume attractiveness is a relative condition, superseded by the way that readers choose to love their characters. Personally, I think it’s very sexy of me to love Tenzo. All this to say, don’t worry about it. Who cares? I just made you read a quote about people wanting to have sex with the Once-ler. Think about that. 

The number of fics at the time of my making these charts was 6,969 though, so I think we’re all winners here. 

Limitations 

As I used the manga interaction counts from 2018, bias in my methodology then is still present here. 

In my original calculations, I actually had Obito at 35.8% instead of 35.0% for Figure 2, in a case of human error of inputting 49/137 instead of 48/137 in my calculations. This error has been noted and changed, but the potential for more human error is present in all of my calculations. 

I am aware of there being an event going on for Kakashi and Iruka as I write this, so it is possible that by the time this data is analyzed the number of AO3 fics will have increased. 

I will reiterate that I exclude sensei/student pairings (Sakura and Naruto being two of Kakashi’s top five pairings on AO3 in general; currently third and fourth respectively) because of my own discomfort and the fact I am making a comparison with their manga interactions, which take place when both students are 12-16 and Kakashi is 26-30. Minato would currently be the next highest after original characters, excluded for similar reasons. I also include Itachi with reluctance due to their age gap, but as he is at the very least 18 when returns to Konoha to speak to Kakashi, and he is the next highest in Kakashi pairings, he acts as the fifth pairing. So, in short: I am most certainly biased in what I included and excluded in my 2018 and 2020 data. 

Again, this analysis does not examine a number of variables, like the Naruto anime and ongoing sequel anime, other types of pairing content, etc. But it’s still very interesting to see the tide of fic on AO3. I would like to look at the anime specifically at some point, but this was already an incredible waste of time. 

Seriously, why would you read this? Why would I write this? Are we human, or are we dancer? We will never know.

The science of SnK returns!

Okay, it’s been a weekish since the second half of the third season started so it’s time to do some science! Well, for me to do some science. It’s time for you to read and wonder why I have so much free time! 

ANYWAY! Today we are looking at the big hairy boy. The Beast Titan. I’ve really been looking forward to this because today there are no complicated chemistry formulas or quantum entanglement. Just good old fashioned Newtonian physics.    

So today I am going to work out how hard the Beast Titan threw this rock. So we have two questions first of all. How big is the rock? And what is the rock made of? The first one is easy. 

using this frame and the Beat Titan’s cannon height of 17 meters I can use pixel measurements to figure out this rock is roughly (It’s not a perfect sphere but close enough) 2.8 meters across and thus has a volume of 11.49 meters cubed. Now figuring out what the rock is made of is impossible so I’m just going to use granite just cuz. So the density of granite is 2650kg per meter cubed so with that and the volume we can work out the rock weighs about 30448.5 kg. So, like a lot.   

Next, we need to know how far he throws it.

Using this frame, the cannon height of the walls of 50 meters and some more pixel measurements we know the Beast Titan throws this hefty boulder about 327 meters (Since the camera is at an angle the distance could be a little different but this is the best I got) So counting from the moments the rock leaves his hand it takes on average about 10 seconds to hit the gate. This gives it a speed of 32.7 meters per second. Using the formula for kinetic energy we get... 16270000 joules, turn that into newtons and we get... okay.   

THAT IS THE FORCE OF THE SATURN V ROCKET AT TAKEOFF. YOU KNOW, THE ROCKET THAT TOOK PEOPLE TO THE DAMN MOON! NO WONDER IT CAUSES THE GROUND TO SHAKE WHEN IT HITS! 

Okay... deep breath. Caps lock aside this kind makes sense. The Beast Titan throws the boulder like a shotput thrower at the Olympics. His round, pot belly allows him to build up a lot of rotary force and his longs arms allow him to really build up a lot of acceleration. Speaking of which it is time for my favorite bit of these!  

HOW DEAD SHOULD LEVI BE?

The last two of these I talked about how dead Levi should be and people seemed to enjoy it so lets to it again. If the Beast Titan threw Levi with the same force he threw that boulder he would accelerate at a rate of...3568 meters per second per second... wow. That is 356g. Like. 10 times faster than the speed of sound. Forget sheering trauma or hypovolemic shock Levi is a fucking puddle at this point. That rock accelerates for about 4.5 seconds so lets so Levi does as well. A human at most can survive a little over 100g for a fraction of second and about 40-45g for a few seconds. Levi is going from 0 to 3568 meters per second in not a lot of time. His blood would boil, his skin would melt, eyes would explode and bones turn to dust in the blink of an eye. 

Think that but like a million times worse. And more dead. A more liquid. So yeah. Levi is super, super really absolutely dead! 

If you’ve read this far then I really want to thank you. Doing these takes quite a while and I really appreciate the fact that people seem to like these and hey, maybe you learned a thing or two. I’ve got some more planned as well to do with this season but if you have any ideas or questions then send them my way! Once again thank you!

Shouto Todoroki: A Quirky Genetic Case Study

(Spoilers for BnHA and Biology Class) 

In a world of superpowers, Todoroki Shouto stands alone as a master of two quirks. A physiological impossibility, while some have the power to borrow or steal quirks, only Shouto naturally holds more than one. 

Let’s dive in to the “science” behind quirks. They are genetically-linked, but not actually part of the genome. Quirks are most likely carried by epigenetic factors or something similar to mitochondrial DNA. The implications of this: quirks are hereditary, but not predictable like normal traits. 

There are two common cases. 

1) Parents with incompatible quirks have offspring with either one of the parental quirks. Since holding two quirks is generally impossible, one must win out, or the pairing will not be viable. 

2) Parents with compatible quirks have offspring with a new quirk. However, the combination is unpredictable. For example, telekinesis and fire breathing might combine to cancel out the quirk factor altogether. 

And then there’s a rare third case. One that, through miraculous luck, passes both parental quirks on to their offspring.

Shouto is what's known as a chimera. Specifically a bilateral chimera, meaning his left and right halves are genetically distinct. The bird pictured above is a real world example of this phenomenon. It’s actually a gynandromorph; half male and half female.

So, what causes chimerism? Basically, it occurs when twin (typically fraternal)  zygotes merge early in development. But that's not quite the full story for Shouto.

Each half of the DNA from either parent carries the epigenetic quirk factor. Although the DNA they’ve formed is technically viable, these two quirk factors can’t exist together nor combine into a new quirk factor.

With two incompatible quirks, the DNA is pulled apart by the quirks’ opposing forces. After splitting, the halves replicate themselves as normal, forming two genetically distinct cells. Either new cell could act as a viable zygote, or both could which would result in identical twins with different quirks. Or, very rarely, something like this could occur:

Both halves of the original DNA go on to form zygotes, but the two zygotes merge at some point early in their development. This could create a mosaic chimera (a mix of both throughout the body) or a bilateral chimera (separated into two hemispheres).

In Shouto’s case, the zygotes merged back together bilaterally. Cells with fire quirk factors formed his left half, and cells with ice quirk factors formed his right. His DNA is the same in every cell, but each half carries epigenetic factors from a different parent.

Through this unlikely course of events, Shouto has the unique ability to wield two quirks at once. What’s more, his internal conflict between his mother and father turns outward, reflected down to the genetic level.
