When Sig met with Boss Nekomamushi alone, he showed him Kozuki Hiyori's letter—just to show him; it was not only for Inuarashi and Nekomamushi, but also for Izo.
In her letter, Hiyori primarily followed Sig's instructions, stating that "Sea King is a friend of the Kozuki Clan," "Siegfried is highly trustworthy," and "He also helped his father avenge his father and killed Kurozumi Orochi"...
As for the others, Hiyori tried her best to explain, but Boss Nekomamushi really couldn't understand.
Why did Kaido's daughter become his son? And Hiyori's husband? How did the Shogun become "Kozuki Yamato"? And what's this plan to expel Kaido...?
Understanding this part of the letter is not easy at all!
At most, all we know is that the situation in Wano Country has improved considerably, and Kurozumi Orochi has been defeated. Although they are still under pressure from Kaido, at least there is a "shogun of the Kozuki Clan" mediating for the people of Wano Country... Let's just assume that's the case for now!
What's easier to understand is that all of this was brought about by the current Sea King, so he is indeed the benefactor of Wano Country, Kozuki Hiyori, and the Kozuki Clan.
Having understood this, the Boss Nekomamushi immediately believed Sig's claim that "someone has become like him."
At this point, it didn't matter much whether Inuarashi had been stabbed or not; that dog was tough as nails anyway...
Nekomamushi was more concerned about Wano Country and Hiyori's affairs. Due to time constraints, he couldn't get much information out of Sig, but they agreed that Sig would accompany him back to Wano Country after things were resolved.
Based on the handwriting, some coded messages, and his memories, Nekomamushi was indeed convinced that the letter was written by Hiyori, but... the content was too bizarre, and he had to go back and check it to be at ease.
And according to the letter, it seems he can go back now? After all, isn't the general "one of our own"?
As for the assassination of Old Dog...
Actually, Boss Nekomamushi never suspected Shanks from the beginning. Although Shanks was just an apprentice crew member and a fifteen or sixteen-year-old boy during the year they were on Roger's ship, Shanks still remembered the favor Boss Nekomamushi had secretly bought for him catnip.
From the very beginning, his suspicions were directed at the dubious Fish-Man named "Siegfried"!
Now that he had received Hiyori's letter, Nekomamushi trusted Sig completely and readily followed Sig instructions to begin the plan.
On one hand, they give the "Wanda" mentioned by Sig, whose emotions are clearly off, a chance; on the other hand, they search for the real Wanda...
And that's how this scene came about!
Seeing that the real Wanda had been rescued, the fake Wanda knew she could no longer continue pretending and scoffed in annoyance.
Then, her figure changed, and the image of a female pirate with a long nose and a fierce appearance appeared on the spot.
Katrin Deme!
Known as "Moonfang Hunter," this vicious pirate first appeared as Prisoner in Impel Down, where she was the "most vicious female prisoner" at the time. Later, during Impel Down Blackbeard, she joined the Blackbeard Pirates and became the Captain of the sixth ship. Two years after the Marineford, she even used her transformation ability to ambush Gecko Moria.
This female pirate is still roaming the high seas of the New World.
Her transformation method is clearly different from the "Copy-Copy Fruit," but somewhat similar to the "Mirror-Mirror Fruit." It seems that a layer of "illusion" disappears around her body, and then her original appearance appears.
Although it didn't actually change his body, it greatly enhanced his ability to confuse the five senses and Observation Haki — Shanks hadn't noticed anything about it before.
Sig only noticed the anomaly through her emotions. When Wanda first saw him, her emotion was "surprise," which was somewhat different from others, but the overlap was still quite high.
After all, it's certainly welcome when the "culprit comes forward."
But afterwards, her emotions became increasingly skewed, not the emotions one should have towards the "murderer," but more like an attitude towards a "scapegoat"!
So Sig also took notice of her.
"Katarina Demere? So it really is you?" Sig was still slightly surprised.
There are only a few types of Devil Fruits on the high seas that can mimic others. The "Copy-Copy Fruit" and the "Mirror-Mirror Fruit" belong to the younger brother and sister-in-law. Moreover, she just used other deceptive abilities. Sig should have been able to guess that she is a user of the Mythical Zoan, the Dog-Dog Fruit, in its Nine-Tails Fox Form!
At first, Sig did think so too, and he was even worried for Wanda. Although Wanda appeared in the original work, what if she got killed by her own butterfly's wings?
"Heh, you only just guessed it was me?" Katrin Deme grinned, looking even fiercer.
"No, it's not that I just guessed, it's just that there are rumors on the high seas that you've always been ruthless towards beautiful women... The Nine-Tails Fruit's imitation is just an illusion, it shouldn't require the object to be alive, right?" Sig said, glancing at Wanda was still alive.
Sig was initially worried that if it really was Katrin Demere, Wanda would only find her body.
It was upon seeing Wanda alive that Sig began to suspect that "she" was not Katrin Demere.
After Katrin Demey went to prison, her news and reputation were completely blacklisted because of her viciousness and cruelty.
With her ferocious appearance, she would kill women more beautiful than herself, and would even actively raid towns with weak defenses, slaughtering women there who were more beautiful than herself—basically, as long as they were young, the probability of them being "more beautiful than her" was extremely high!
However, upon hearing Sig's question, Katrin Deme was first taken aback, then angrily retorted, "Are you insulting me?"
That's right, Katrin Deme has another principle—never kill a woman uglier than herself.
A woman from the Mink Tribe —well, she can be considered a woman, and... she was a dog! Why would I kill her?
As Sig realized this, he suddenly felt Violet's questioning gaze. A step later, Lucky Roo, Yasopp, and the others also cast strange glances at him...
I have a feeling like I've revealed something?
Of course, the Mink Tribe were still puzzled—wait, this ugly woman still hadn't explained why she hadn't killed Wanda. Wasn't she supposed to kill women more beautiful than herself? Wanda was much prettier than her...
"So, was her reputation ruined?"
"It's not actually that vicious?"
"Yes, the World Government lies all the time..."
"So she was framed. How pitiful. She didn't even kill Wanda, yet she was rumored to kill any woman more beautiful than herself."
"Why did you want to assassinate Duke Inuarashi? If you have any difficulties, you can tell us!"
The kind-hearted Mink Tribe expressed their sympathy, while Katrin Deme had already erupted in fury...
