To once again highlight Oda’s deep love for Japanese culture and literature — especially prominent throughout the Wano arc — I wanted to share this direct visual nod to Katsushika Hokusai’s legendary woodblock print, "The Great Wave off Kanagawa."
Chapter 910.
It’s nearly identical!
In the anime (episode 891), they took it a step further. To emphasize the woodblock print aesthetic, several frames were stylized to look exactly as if they were painted directly onto a wooden canvas!
And with that, let’s begin!~
Shimotsuki Yasuie is a distant relative of Zoro. In Chapter 941, as well as from the title of Chapter 942, we learn that he is the Daimyo of the Hakumai region. And right here, we (once again) encounter Oda's favorite thing: wordplay, specifically his favorite theme — food!
In Japanese, the Hakumai region in Wano is written as "白舞" (White Dance). However, phonetically, it sounds ABSOLUTELY identical to the word Hakumai — "白米".
Hakumai (白米) literally translates to "white rice" — the exact type of rice used to make Sushi and Onigiri! This is a classic food-related pun by Oda, very much like Zoro's "Oni Giri" technique (which doubles as "demon cutter" and "rice ball").
You can read more about this wordplay here.
Yasuie’s execution takes place in the Rasetsu Town (羅刹町, Rasetsu-chō), an area of the Flower Capital where people are imprisoned for crimes against Shogun Orochi and Kaido — including showing loyalty to their enemies, the Kozuki Family. The district is named after Rakshasas (Rasetsu in Japanese mythology), fierce, man-eating demons. This name heavily emphasizes the grim and brutal atmosphere of the location.
Once again, it is confirmed that "Ushimitsu Kozo will die alongside Komurasaki" — a direct nod to the tale of Komurasaki and Shirai Gonpachi, who died on the very same day (which I covered in my previous post here).
As I have mentioned multiple times: Wano is the "Arc of Lies," and this theme is strongly reinforced here! Yasuie not only lies about being Ushimitsu Kozo, but he also claims he created the rebellion's picture image just to "play a prank" on Orochi. In reality, he sacrifices his life and uses this lie to save the alliance, giving the rebellion a second chance.
A noble lie for the greater good.
In this chapter, we once again witness Oda’s brilliant use of double entendres. The phrase "A man of such small caliber shall never in his life truly devour Oden!!" carries a clever dual meaning: it implies that someone as petty as Orochi could never truly finish a bowl of oden soup, while simultaneously declaring that he could never truly best or digest the legacy of Kouzuki Oden (the legendary man himself).
Furthermore, Orochi constantly refers to Yasuie as a "rat." This isn't just a basic insult — it’s another intentional linguistic pun by Oda! Yasuie’s actual nickname is "Yasu the Hedgehog." In Japanese, the word for hedgehog is Harinezumi (ハリネズミ / 針鼠). Literally, it translates to "needle mouse" or "spiky rat," where 針 (hari) means needle and 鼠 (nezumi) means mouse or rat.
Yasuie's dialogue placed right over Zoro's panel feels like a deliberate narrative misdirection. It was designed to trick the readers into believing that Zoro would be the one to defeat Kaido — a theory that a massive part of the fandom genuinely bought into while Wano was airing. There were so many signs pointing toward Zoro taking Kaido’s head, and that very well could have been the case… if Wano wasn't established as the "Arc of Lies!"
To wrap it all up, this chapter brings us back to the horrifying reality of the "SMILE" fruits, which Doflamingo was manufacturing for Kaido. A plot thread that Oda planted over 300+ chapters ago, finally revealing its devastating truth...
The chapter cover features a classic Oda "foreshadowing" moment, subtly hinting at Robin’s future battle against Black Maria, who possesses the spider-model Devil Fruit.
In my opinion, Zoro connected the dots the very second he heard the name "SMILE" — even before Hiyori explained why the people of Ebisu are forced to "smile" through their pain. That’s exactly why he is drawn with such a grim, heavy expression here.
Side note: If anyone is somehow bothered by Robin standing next to Franky in these panels — calm down. He is huge, and the artist simply needed to fit his massive design into the frame layout.
We also see Sanji’s reaction to the realization that the people of Ebisu were starving. For Sanji, the theme of hunger is deeply personal, striking at the very core of his character and backstory.
Look at Zoro’s reaction. He recalls Yasuie’s words about laughter. His fury is so intense that the veins on his face and neck are literally bulging!
Right after, Hiyori spots Toko, and Sanji notices her too. Notice how Robin’s reaction mirrors Hiyori’s! Meanwhile, Usopp explains to the trio that Toko is Yasuie's daughter, as an old woman had just revealed this truth to him and Nami in the previous chapter. Franky is visibly shocked by the news.
Then, Orochi notices Toko and immediately prepares to execute her. He acknowledges her as Yasuie’s daughter, claiming that her "laughter" was the reason Komurasaki had to die, and declares that "two generations of her family have earned his wrath."
Orochi is completely delusional and unhinged. He utterly refuses to acknowledge that her laughter is a direct consequence of the artificial SMILE fruits — crimes that he himself committed!
And, of course, the scene where Sanji and Zoro step in to protect Toko from Orochi.
Interestingly, Oda chose to have Zoro be the one who physically catches and holds Toko, rather than Sanji.
Why do you think he did that? Especially considering that shortly after, Zoro hands Toko over to Sanji, Sanji passes her to Usopp, as a result, Toko ends up directly under Robin's care..
Next, Zoro hands Toko over to Sanji and launches a direct assault on Orochi using his "720-Pound Phoenix" technique. However, Kyoshiro (Denjiro) suddenly steps in and blocks the attack, saving the Shogun's life. Even though Zoro is wounded here, his slashes are still incredibly powerful, so Denjiro managing to deflect them easily establishes him as an exceptionally skilled samurai and swordsman.
As a fun side note: On the page where Zoro attacks Orochi, Oda includes a panel of Robin. Yet, on the page where Denjiro blocks the strike, the focus shifts to Hiyori… that’s just a little detail.
Here, I want to take a quick detour to explain how the numbering of Zoro's cannon/phoenix techniques actually works (you might already know this, but it’s fascinating!).
The numbering is rooted in strict mathematical logic tied deeply to Buddhist philosophy, specifically regarding the human mind and worldly desires. At the core of this formula lies the Buddhist concept of the 36 earthly desires (passions) that corrupt the human soul.
The number 36 is calculated by multiplying human senses, perceptions, and time:
6 senses: sight, hearing, smell, taste, touch, and mind;
3 types of perception: good, bad, or neutral (6 × 3 = 18);
2 qualities of the soul: pure or corrupt (18 × 2 = 36).
The final power and name of the technique depend entirely on how many swords Zoro is currently wielding. He simply multiplies the base 36 desires by the number of blades:
1-Sword Style (Ittoryu): 36 × 1 = 36-Pound Cannon
2-Sword Style (Nitoryu): 36 × 2 = 72-Pound Cannon
3-Sword Style (Santoryu): 36 × 3 = 108-Pound Cannon
After his two years of training with Mihawk during the timeskip, Zoro’s power increased proportionally, so Oda simply multiplied everything by 10:
1-Sword Style: 36 × 10 = 360-Pound Cannon
2-Sword Style: 72 × 10 = 720-Pound Cannon (the one he uses here against Orochi)
3-Sword Style: 108 × 10 = 1080-Pound Cannon (used against Pica in Dressrosa)
This proves once again that Zoro is actually excellent at math!
also 7 and 2 the official numbers assigned to Robin and Zoro...
Next up, we get a Zoro x Franky shipping scene.
Joke!
What actually happens is Franky swooping in to shield Zoro from incoming gunfire. This is like a mirror to how Franky shielded Robin back in Enies Lobby — also from a barrage of bullets! Franky is truly nakama, protecting both halves of our favorite couple with equal devotion. We love him for that!
Right after, Franky retrieves Yasuie’s body. This is a moment for Zoro: he is now completely free to fight. He doesn't have to worry about Toko's safety (Sanji has her), and he doesn't have to worry about securing Yasuie's body (Franky took care of it).
We also see Usopp covering Franky’s back — which is logic, considering Franky’s back is his only vulnerable spot without metal armor.
The anime adaptation (Episode 942) expands on this sequence beautifully, showing a perfect chain of teamwork: Robin covers Usopp, and Nami covers Robin. Great teamwork!
Meanwhile, Kyoshiro (Denjiro) claims he is protecting Orochi because he is "the Shogun’s dog." Which, as we know, is another lie. In my opinion, Denjiro stopped Zoro from killing Orochi for one calculated reason: if Orochi died right then and there, Kaido would have immediately descended upon the Flower Capital. He wouldn't just destroy the city; he would slaughter everyone in sight, completely ruining any chance for the actual Rebellion plan to succeed.
This chapter also finally unmasks the true identity of Hitokiri Kamazo. I actually did a deep dive into this character in my previous (second) post, which you can read here.
Killer and Kid are captured and brought back to Udon.
Let's talk a bit about Udon.
The Udon Prisoner Mine is a reference to the industrialization of Japan during the Meiji Restoration and the forced labor camps of the late 19th and early 20th centuries, cleverly blended with traditional Japanese food culture.
During the Meiji era, Japan underwent rapid modernization. Political prisoners and criminals were exiled to remote, undeveloped territories (most notably to Hokkaido, inside the infamous Abashiri Prison) to build infrastructure, mine coal, and fuel heavy industry. Just like in real history, the prisoners in Udon aren't just sitting in cells — they have been enslaved to build weapon factories and manually quarry stones to enrich their occupiers.
Furthermore, after the abolition of the samurai class in real-world Japan, many former warriors who rebelled against the new regime were sent to these penal colonies, where their pride was systematically broken through brutal, grueling labor. Oda mirrors this historical tragedy perfectly: former Yakuza bosses, samurai, and loyal retainers of the Kozuki clan have spent years breaking their backs in Kaido's mines, waiting for their spirits to finally sap away.
And, of course, Oda’s favorite theme — food — makes its appearance here as well.
Udon is, famously, a thick Japanese wheat noodle. It is deeply ironic that inside a prison named after food, the inmates are given meager kibidango as payment for slave labor. Meanwhile, Queen is utterly obsessed with oshiruko (a sweet red bean soup with mochi). To wrap it all up, Big Mom is currently marching right toward them for that exact same reason — for oshiruko!
Chapter 945.
Zoro continues his fierce clash with Kyoshiro (Denjiro), but things get complicated when the Orochi Oniwabanshu ninjas arrive on the scene and attack Zoro!
Do you remember who had to deal with the Oniwabanshu just a few chapters ago?
That’s right — Robin!
I did a comprehensive breakdown of the Oniwabanshu in my previous (second) post, which you can check out here. As a quick reminder, Oniwabanshu literally translates to "people of the noble garden."
Meanwhile, Sanji safely passes Toko over to Usopp.
Meanwhile, Brook steps up to protect Hiyori.
Yet, for some reason, I don't see any "Brook x Hiyori" shippers around… Pretty strange, isn't it?
Naturally, Sanji’s inner "woman radar" goes off, and he immediately catches wind of Hiyori being in danger and rushes to her rescue.
However, he failed to realize that Oda had a completely different "plan" in mind…
Zoro swoops in to save Hiyori. It’s honestly not surprising at all, considering he’s the only one in the crew who actually knows she is Momonosuke’s sister. And, he is annoyed at her again for her… "foolishness."
And now, we finally arrive at the exact moment that, in my opinion, justifies why this entire sequence was written in the first place...
This honestly reminds me of that scene in the Enies Lobby anime where Sanji desperately tries to catch Robin as she falls, only for Franky to scoop her up instead (it never happened in the manga).
I truly believe this entire farce was written just for the sake of this punchline. It’s classic author behavior, always finding ways to "bully" Sanji for comedic relief.
From SBS of this chapter(945). (SBS of Volume 94!)
A small detail for attentive readers!
We are greeted by a beautiful cover from the very same author "I don't want to draw romance" and "shonen manga is for boys, they aren't interested in romance." Yet, here we have Kin'emon and Otsuru on a literal nighttime DATE by foxfire-light!
Quick reminder: at this point in the story, Kin'emon is de facto 36 years old, while Otsuru is 55.
Funnily enough, I don’t see anyone screaming about the age gap!!
As a daily reminder, "fox" in Spanish is Zorro.
Tanuki - exact animal Chopper is constantly mistaken for throughout the Wano arc.
Tsuru (Otsuru's name) literally translates to "crane" in Japanese — Robin’s official animal representation!
I don't have too much to say about this chapter as a whole, but this is where Luffy uses Ryou (Wano's brand of Haki) for the very first time to remove the exploding collars. This mirrors exactly what Rayleigh did back in Sabaody when he freed himself, the giant, and Camie.
That happened all the way back in Chapter 504 — 442 chapters ago! (in chapter 947, Oda actually redraws new panels illustrating that Sabaody scene).
More importantly, it is right here that "Flower" Hyogoro drops a pivotal piece of wisdom that will truly come to fruition later on Onigashima.
He states: "It is in the midst of danger that power truly blossoms!!!"
And that is precisely what we are going to witness moving forward!!! Not just with Luffy, but also with Zoro and Robin!!
Chapter 948.
Kiku puts on her mask, and everyone instantly recognizes her as "The handsomest swordsman of Wano"… who is also biologically a man. With this, the author unveils yet another "lie" in this intricately woven "Arc of Lies."
It's easy to mistake her mask for a generic Oni mask, but it is specifically a Hannya mask!
There is a very important distinction here, much like between a Samurai and a Ronin.
While every Ronin is a former Samurai, not every Samurai is a Ronin.
The same logic applies here:
every Hannya is an Oni, but not every Oni is a Hannya!
In Japanese mythology, Oni is a broad term for the entire race of demons. A Hannya, on the other hand, represents a very specific entity — a woman who has transformed into a monstrous demon due to overwhelming jealousy and grief.
In traditional Japanese Noh theater, the Hannya mask possesses a haunting dual nature. When looked at straight-on, it projects a terrifying, wrathful demonic sneer. However, if the actor tilts the mask slightly downward, the angled eyebrows and shifting shadows create the profound illusion of a weeping, deeply sorrowful face.
(If you remember, I previously wrote about Noh theater in relation to Robin in my very first post of this series, which you can read here).
Kiku deliberately puts on this mask before a battle to conceal her soft, feminine features and present nothing but unyielding fury to her enemies.
Oda truly knows exactly what he is doing!
To top it all off, "Old Man Hyo" is finally revealed to be the legendary Hyogoro of the Flower — marking yet another broken illusion in Oda's "Arc of Lies".
Chapter 950.
Zoro easily defeats the ninjas sent after them. We find them taking shelter at the Enma Shrine (!!foreshadowing), located deep within the forest of the Hakumai region — the very land once ruled by Yasuie.
Hiyori apologizes, calling herself a burden to Zoro. He bluntly agrees but tells her not to worry about it, adding that if he lets her die, he’d have to answer to Momonosuke. Zoro then asks if she plans on returning to "that house in the snow." In my opinion, he asks this because if she goes back there, it gives him a direct path back to the bridge where the "sword thief" is hiding.
When Hiyori expresses her deep worries about Toko, Zoro reassures her, saying Toko will be fine (physically speaking, at least) because he left her with "his people".
He has zero doubts because he knows for a fact that Robin will take care of her.
Throughout this entire interaction with Hiyori, Zoro's mind is completely occupied by his missing sword and the cryptic words Gyukimaru told him. Hiyori offers to guide him back to the famous Bandit's Bridge of Ringo, and Zoro declares to avenge Yasuie's death — to which Hiyori responds that she wishes to kill Orochi with her own hands.
Chapter 951
Some say that since Frankie offered Robin a ride on his motorcycle, it means they are a couple..
Well, going by that exact logic, Franky and Nami are also a couple, since she’s riding with him too…
Moving on, Robin takes Toko from Brook, and her words to him are brutal, but honest xD. This completely mirrors Zoro's bluntness from the previous chapter, when he openly agreed that Hiyori was a burden.
And then, we are blessed with one of the absolute sweetest panels in the entire arc! It gives pure, heartwarming "mother and daughter" vibes. The only thing missing from this perfect picture is the "dad," Zoro…
Zoro clashes with Gyukimaru once again to reclaim his sword. Gyukimaru explains that Shusui is Wano’s stolen national treasure, once wielded by the God of the Blade (Ryuma). Naturally, Hiyori is completely shocked to hear this, as she knows the full weight of Shusui's legacy.
Kawamatsu interrupts the fight by hurling his sword, which Zoro deflects with ease — much to the Kappa's surprise. This chapter also gives us the emotional reunion between Hiyori and Kawamatsu.
Now, I won't say a word here.
I'll just leave you with these two panels of Zoro reacting to two completely different reunions…
In this chapter, Kawamatsu tells the story of the Daimyo of Ringo, Shimotsuki Ushimaru (who happens to be Zoro’s relative), and his loyal fox companion, Onimaru. (I covered a bit about them in my previous post, which you can read here).
Upon realizing that Zoro’s blade is the legendary Shusui, Hiyori begs him to return it to its rightful place in Wano. Zoro, completely true to character, instantly refuses!
To sway him, Hiyori offers a trade: she promises to give him another weapon in return — Enma, the legendary katana inherited from her late father, Oden, and the only blade to have ever left a scar on Kaido.
Chapter 954 kicks off with a countdown: only 7 days remain until the raid on Onigashima!
Hiyori explains the legacy of Oden’s swords and, once again, pleads with Zoro to return Shusui. Zoro deduced that Moria was the one who stole Shusui (which is completely correct) and ultimately agrees to the deal — but strictly as a fair exchange. He will return the sacred treasure only if he gets Enma as a replacement, and only if he is allowed to visit Ryuma’s grave later.
So that is, this is not just a gift from Hiyori, but a mutually beneficial exchange (she asks Zoro twice to return Shusui).
Robin expresses her deep admiration for Yasuie, saying, "This Yasuie… was an incredible man…" It’s a brief but incredibly significant moment for the bigger picture, and I’ll definitely be returning to this point later on!
In this chapter, we finally get only the second moment in the entire Wano arc where Zoro and Robin share the exact same frame (the first one was at the very beginning, in Chapter 909). Looking at the anime adaptation (Episode 955), we can see they are actually sitting quite close to each other, though Oda, true to form, just had to stuff someone else between them…
Then again, considering Wano is explicitly established as the "Arc of Lies," I would honestly be more worried if they were sitting right next to each other!
Chapter 955, Episode 956.
Huge shoutout to TOEI Animation for actually giving us more frames of them together compared to the manga author xD
In this chapter, Zoro officially receives Enma, while Kiku returns Nidai Kitetsu.
So, two blades: Ame no Habakiri and Enma.
Ame no Habakiri: The "white" sword destined to slice through the Heavens.
Enma: The "purple" sword destined to split the earth straight to the bottom of Hell.
Which one ends up with Zoro?
Honestly, even if I hadn't watched the Wano arc at all, I could tell just by looking at them which sword was meant for Zoro xD
In Japanese culture, Enma-o (閻魔大王 — Great King Enma) is the ruler of the underworld (the Buddhist hell, Jigoku) and the ultimate judge of the dead. This figure integrated into Japanese folklore alongside Buddhism, originating from the Vedic god of death, Yama.
According to traditional Buddhist beliefs, once a person dies, their soul is brought before his court. Enma acts as the supreme magistrate:
He reviews the person's deeds using special scrolls and books where every single sin is meticulously recorded.
His courtroom features a magical mirror called Johari no Kagami, which reflects the absolute, unvarnished truth of a person’s earthly life, exposing any deception.
Based on these findings, Enma determines which of the six realms of reincarnation (Samsara) the soul will pass into, or what specific torment in hell they must endure.
Here is a fascinating detail: there is a famous Japanese children's saying: "If you tell a lie, Lord Enma will pull your tongue out" (嘘をつくと閻魔様に舌を抜かれる). It is traditionally used to scare kids into telling the truth.
Quite ironic, considering the "Arc of Lies", isn't it?
A few words about Ame no Habakiri as well.
Ame no Habakiri is named after the mythical sword used by the storm god Susanoo to slay the legendary eight-headed serpent, Yamata no Orochi! (I briefly touched upon the legend of Susanoo and its connections to Oden and Denjiro in my previous, third post here).
Because of this, the moment these swords were introduced, the reader familiar with Japanese mythology could have deduced that Zoro would not be the one to deal the killing blow to Orochi!
Ame no Habakiri symbolizes the heroic triumph over a monster.
Enma, on the other hand, symbolizes judgment, an ordeal, and the heavy price one must pay for absolute power.
Oda’s choice here could be seen as follows: one sword embodies a legendary feat, while the other represents an unrelenting judgment and an internal trial.
This is precisely why Enma fits Zoro so perfectly — his strength has always been forged through pushing past his absolute limits.
But there’s even more to why Enma is the perfect for Zoro.
Zoro once swore an oath that his name would "reach the heavens." Strictly speaking, it would have made more narrative sense for him to wield Oden’s other blade, Ame no Habakiri — the sword explicitly destined to slice through the heavens. Yet, he was given Enma instead. Why?
Let's look closely at Enma:
It is Zoro's seventh (7) sword — 7 is Robin's official number.
It features a distinct purple color scheme — Robin’s signature color.
It is adorned with floral patterns — Robin’s symbol.
Its tsuba (handguard) is shaped like a trefoil (clover) — visually connecting it directly to Professor Clover and Ohara (Robin’s past). I actually did a breakdown on this specific detail here.
Even if you want to argue that the last point feels like a stretch, the first three are absolutely undeniable.
Just like it is undeniable that all the way back in Chapter 265, Robin fought against a character named Yama! I remind you that, King Enma’s mythological origins stem directly from the Buddhist/Vedic god Yama. And guess who is featured on the cover page of that exact chapter? Zoro, sporting the Shimotsuki clan crest on his outfit!
Furthermore, Zoro receives Enma exactly seven (7) days before the raid on Onigashima. There is that number 7 popping up again.
It's also worth noting the lineage of these blades.
Ame no Habakiri was forged by Tenguyama Hitetsu (Momo and Hiyori’s grandfather).
Meanwhile, Enma was crafted by Shimotsuki Kozaburo — Kuina’s grandfather and a direct blood relative of Zoro himself!
It seems Oda deliberately avoided tethering Zoro to Hiyori through this sword. Instead, for some reason, he chose to lace Enma with an overwhelming amount of Robin’s "symbolism"…
In essence, Zoro simply reclaimed what was rightfully his. It's funny because Shusui (Ryuma's sword) also belonged to Zoro by bloodright, given his ancestry.
On top of that, Enma stands out beautifully against Zoro's other blades, creating a striking contrast that proves once again just how perfectly purple (Enma/Robin) and green (Zoro) complement each other!
Metaphorically, Enma is the Japanese equivalent of Hades, the King of Hell. By weaving all these details together, Oda planted a massive narrative anchor that binds Zoro to Robin's imagery.
No matter where Zoro wanders, "Robin" will always be with him!
Robin arrives with Toko at Yasuie’s grave. Out of the entire crew, only Robin and later Zoro make the time to personally visit Yasuie's resting place!!
In the panel directly beneath them, Zoro is hard at work training with Enma when Hitetsu approaches him. Later on, Toko will stay behind under Hitetsu's protection while Robin and Zoro head out to Onigashima.
Hitetsu reveals to Zoro that both Enma and Wado Ichimonji were crafted by the exact same blacksmith — Shimotsuki Kozaburo. He suggests that Hiyori recognized the Wado, which is likely why she trusted Zoro with her father's memento, Enma. Hitetsu also points out that Enma has not yet been forged into a "black blade." This serves as a major narrative callback to Mihawk’s crucial lesson during the timeskip: any sword can become a "black blade". Not just temporarily coated in Armament Haki, but permanently turned pitch-black — just like Mihawk's Yoru or Ryuma's Shusui.
(we saw this flashbacks in Dressrosa after Zoro defeated Pica, all the way back in Chapter 779).
In a way, Hitetsu acts as a "bridge" for Zoro and Robin, much like Toko. Look at the narrative connections: it is Hitetsu who officially delivers Enma to Zoro, and it is Hitetsu who later guides Robin directly to the hidden Poneglyph.
Also the anime adaptation treats us to an absolutely gorgeous wide shot of our couple! (As you can see from the manga panels, it was barely visible in the source material).
I’m also leaving a wonderful link to a brilliant post diving deeper into this specific frame!
This ended up feeling like a chapter-by-chapter recap of Wano, but it is what it is. I can't help it, alas~
The individual parts of my posts might vary in quality and overall setup because…
Well, there is no strict structure xD.
Unlike Oda, I don't have a master plan layered in advance — I’m simply turning the pages of the manga and going episode by episode through the anime.
Also, as Joe noted in their blog: Toko like a "bridge" between Zoro and Robin. Personally, I believe there are several of these "bridges" scattered throughout the Wano Arc. Once I finish my Wano "recap series", I plan to dedicate a separate, standalone post to all the "bridges," "anchors," and visual parallels linking Zoro and Robin in this arc.
So, I will definitely be circling back to this topic later!
