Mizu's spectacles, and the levels of her disguise

In drafting some more Blue Eye Samurai meta posts, I find myself writing out the comparisons between what Mizu can and cannot hide about herself, and how that affects how she moves through the world.

Like, I get the jokes about Mizu's glasses, if only color contacts had existed back then, etc. etc., and I think (hope) that most viewers don't take the glasses jokes seriously, as in "I don't care about the suspension of disbelief because BES is a cartoon." But I wanted to write these thoughts out anyway without burying them in a text post about something else.

I think the points I'm going to lay out here are viewed very differently by different people, so please feel free to add to this post, reply, or put your thoughts in the tags!

Not only do Mizu's glasses not actually help her that much, there's surely more to Mizu's mixed race appearance than just the color of her eyes.

In my view, this was pointed out in episode 1:

I'm willing to bet most of us were expecting young Taigen to say "blue eyes," not "ROUND eyes."

Obviously this is still about Mizu's eyes, but not even spectacles can hide their shape.

I don't think the show is obligated to point out everything about Mizu's face that isn't quite as Japanese as the people around her expect. Though the creators have said that they specifically designed Mizu - and her clothes - to read both as "white" and as "Japanese," as well as both male and female. I think there's more about Mizu's features that read as "white" than just her eyes.

This is where my own headcanons start entering the picture, but it's my impression that people can just tell that Mizu looks different, whether or not they can put a finger on exactly how.

There's the little girl who looks at Mizu and then hides on the way into Kyoto:

When there's more to your face you'd like to cover up than just your eyes, big hats are a big help!

By the way, most of these examples have to come from the first half of the season, since by the second half, either Mizu is too preoccupied with fighting henchmen, or everyone Mizu is facing knows who she is already, and she therefore has no reason to hide her mixed race identity.

It's worth mentioning that the mere fact that Mizu has to hide multiple aspects of her identity - her mixed race and her sex - results in her having to choose clothes that really, really cover her up, which doesn't win her any favors either:

(Zatoichi reference, anyone?)

If it were as easy as, for example, tying her glasses to her head and wa-lah, nobody would ever know she was half-white - then (1) Mizu would've just done that long ago, and (2) Mizu wouldn't be so on guard and on tenterhooks 100% of the time the way she's depicted in the show, even when her glasses are on.

Her spectacles sure don't help her in the brothel, which is full of observant women who are trying to seduce her, meaning they get good long looks at her:

Mizu never takes her glasses off, but they still send a woman to her who has light eyes, thinking that must be what will interest a blue-eyed man:

No wonder Mizu gets mad after this, lol

So Mizu never takes her spectacles off in the brothel, it's dimly lit inside, and the women can still tell that she has blue eyes. I'm getting the sense that Mizu putting on her spectacles isn't a guarantee that people suddenly can't tell that she looks different.

And yet no one spots that she's female.

Mizu can hide her breasts, can wear her hair in the right style, can hide what's between her legs, can walk and talk and behave like a man - and she's been doing it for almost her entire life, to the point that not only is she very good at it, but the threat of being found out as female is deadly, but isn't presented in the show as omnipresent.

Let me explain.

She threatens Ringo for nearly saying the word "girl" out loud, because while she's constantly ostracized for being mixed race, being a woman traveling without a chaperone, carrying a sword, and disguised as a man will get her killed or flogged or arrested or some combination of these things.

But in addition, it's been drilled into her since she was a child that if she is discovered as female, the combination of her being mixed race and female will identify her as someone extremely specific, someone known to some bad people, and she will be killed:

I think of it as Mizu thinking to herself, "Being found out as mixed race means I'm treated badly. Being found out as mixed race and a woman means I'm dead."

Mizu's hair is cut as a child. But she isn't made to wear a big hat, or cover her eyes somehow, or anything like that. Because hiding her sex is a more successful endeavor than hiding her race.

Ringo finds out she's female by accident, but once Mizu accepts the fact that he won't rat her out, she relaxes pretty early on in the season. Because the threat of being found out as female is mitigated pretty much 99.9%, since Mizu has gotten so good at being a man. And also, because most of the time, people see what they want to see. Even if Mizu's face makes her stand out as "not 100% Japanese," no one in the world of BES looks at Mizu's clothes, her bearing, her sword, hears her voice, and will ever in a million years conclude that she is a woman, because expectations around gender roles in the Edo period were so rigid and so widely enforced.

One detail that proved this to me is after the Four Fangs fight:

Ringo takes off Mizu's clothes so he can stitch her up, then leaves her clothes off even after he's done. He doesn't even throw her cloak over her as a blanket or anything. There's a little a straw (pallet?) as a divider there on the left, but anyone could just peek around it and see Mizu and her chest bindings. (I think it's mostly there as a windbreaker.)

And Taigen is right there, but he doesn't give a shit:

Opinions probably vary hugely on this, but my impression is that because the show doesn't make any kind of deal about Taigen being in the room with Mizu here, my guess is that Mizu isn't in any danger of Taigen thinking she's female. Even when I watched the show for the first time, I assumed that Taigen had seen Mizu out of her clothes here, and that he thought nothing of it.

Eat your heart out, Li Shang (Mulan 1998). I actually do think that this scene is a direct and purposeful side-eye to that movie, lol

There's obviously some nuance to how "severe" being mixed race is compared to how "severe" being a woman is for Mizu:

After all, Swordfather can't bear to listen to Mizu confess to being a woman.

So a Japanese man can go wherever he wants, whenever he wants in BES. A Japanese woman has limited options: marriage, religion, or a brothel. A mixed-race man is an eyesore in this story. A mixed-race woman is a death sentence.

May as well eliminate the female aspect, and do what you can about the mixed-race aspect. Because that's just realistic.

Meaning Mizu can avoid the strictures Edo society places on women. But she can't avoid the repercussions that come with being mixed race. And I truly don't think that it's just because "there's no brown contacts yet."

[sad-endings-suck]

Amazing meta (love it), and just to add a quick note on Taigen seeing Mizu with her chest bindings: Mizu seems to bind with sarashi cloth. Which based on my (admittedly little) research, was commonly enough used specifically as a torso binder by both men (to help conceal a larger abdomen) and women (to help with comfort during pregnancy) in Japan during the Edo period! When it comes to samurai specifically, some actually bound their torsos or portions of their torsos with sarashi to help with extreme bleeding when/if they are cut/hurt in combat. So, going back to your statement about people seeing what they expect to see when it comes to Mizu’s gender (which is bang on), I took Taigen’s reaction to Mizu’s otherwise bare chest as evidence that he was not only doing just that, but also further projecting his idea of Mizu as a samurai onto her further. Since a samurai with sarashi chest bindings may even look normal to Taigen, or at least normal enough not to be of notice. And it may even be so little of a “giveaway” as it were, since Ringo clearly thought nothing of it?

#I am truly disappointed that we didnt get absolute confirmation that Taigen saw Mizus bound chest and just didnt think it was a big deal#but I still think that scene is making a point#again I dont think most people take the glasses jokes seriously#but its been bothering me ever since I first saw them#I really dont think Mizu just looks like a 100 percent Japanese person...... with blue eyes#and I bet that will be made even more obvious when she goes to London where Im sure she will meet plenty of people#who are more than happy to point out their observations to her#also I ran out of room in this post to go into it but this is also what made Mizus marriage an absolutely doomed prospect#Mikio talks about wanting to find the right creature for his lord and well... a mixed race woman is the right creature huh#he just needed a little push imo#getting kind of sad at the thought that Ringo is the only person in Mizus life who knows her whole identity AND accepts it wholly

#this is also part of why i think it's very... questionable... for people to attribute mizu refusing to drop the male disguise#as proof of a trans identity. like being found out as a woman is clearly *actively dangerous* to her#the canon so far is open to interpretation but being a woman in disguise IS a valid and frankly very compelling option (via ladyluscinia)

#i don't think taigen saw her imo#ringo was *extremely* protective of her during this moment#more than we see at any other point#my gut tells me off screen ringo set extremely clear boundaries#that taigen was not to come in any further than where he was#and secondly her binding is so tight it doesn't look like she even has breasts under there and#it could easily seem like bandaging if he did happen to get a glimpse#especially since its clear by that point she is often getting hurt#either way i don't think taigen saw OR if he did realized what it was#he was way too much a loyal lapdog to his lord at this point not to rat her out if he knew#it would have restored his honor in a heartbeat to be the one to turn her in#after the teaparty is when he actually developed respect and admiration enough to be tortured#although it does remain a possibility!#i've always found it interesting the way he emphasizes the he/him pronouns when talking to okiyama#so i mean it definitely is possible and maybe he was just so fascinated and flabbergasted#and wanted to see what she was capable of so he just went along with it#idk my gut tells me he doesn't know tho (via moki-dokie)

Meaning Mizu can avoid the strictures Edo society places on women. But she can't avoid the repercussions that come with being mixed race. And I truly don't think that it's just because "there's no brown contacts yet."
