The Sengoku did not deny the words of "Shiryu"...
Indeed, when Sengoku Shiryu, it was because there was a group of people he wanted to send to Impel Down.
The reason I favor Shiryu is because I admire his "arrogance" and his ruthless nature.
Sengoku gave Shiryu a document listing the branches that needed to be "inspected"...
If other Vice Admiral were to go, firstly, there would inevitably be concerns; secondly, it wouldn't be enough to just act recklessly, they would have to maintain their authority, be both intimidating and prevent other divisions from becoming disloyal; and thirdly, and most importantly... there are only a handful of Vice Admiral in the entire Marine Headquarters who are capable of doing this, and Sengoku is reluctant to let them go!
After all, once this matter is resolved, there will be virtually no further developments within the Navy.
As the Marshal, Sengoku knew very well that even in the navy, advancement wasn't something that could be achieved simply by his Marshal!
Garp didn't have such concerns and offered to teach these brats a lesson himself, but Sengoku was worried about his personality.
And Shiryu...
He had neither the need for naval development nor the skills that Sengoku admired— Sengoku could see that Shiryu by no means a reckless man or someone who only knew how to be headstrong!
At the same time, Sengoku will also send his most trusted confidants to accompany Shiryu, firstly as a supervisor, and secondly... to play the good cop and offer rewards. After all, Sengoku doesn't really want to make a clean break; he's just making an example of him. The Navy simply doesn't have the conditions for a clean break right now!
"You will be temporarily granted the rank of lieutenant Headquarters Vice Admiral, as well as the qualification of inspector... Is there anything you need me to do, besides the position of Marshal?" Sengoku asked proactively.
Sengoku has promised that, in addition to accomplishing this task, he will make Shiryu the warden of Impel Down within three years.
This wasn't exactly a misjudgment by Sengoku, but rather because Sig, disguised as Shiryu, displayed immense ambition towards Impel Down in front of Sengoku...
And there are some "psychopaths" who want to capture all the prisoners and put them in Impel Down torture and control them.
Ambition and passion were also key reasons why the Sengoku believed that Shiryu was suitable for this task.
It wasn't that the Sengoku lacked insight; it was simply that Sig, with his "Visionary Path," was far too adept at manipulating mindsets.
Not only was he good at pretending, but he could also accurately judge which level he was on and what personality he should portray in order to make Sengoku feel most at ease.
This led Sengoku to believe he had seen through Shiryu's duplicity and that he understood him perfectly. However, from the first layer to the fifth, it was all an illusion...
Shiryu, without even extinguishing the cigar in his mouth, took the file from Sengoku and said, "I want a Devil Fruit, Mythical Zoan!"
They're practically begging to be ripped off.
Moreover, Shiryu understood that Sengoku's expectation of him at this time was that he would definitely ask for an exorbitant amount, otherwise he wouldn't feel at ease!
As a "Shiryu," proposing such conditions now aligns with the expectations of the Sengoku.
Powerful swordsmen generally reject the use of Devil Fruit to enhance themselves.
After all, a person's energy is limited, especially for sword masters and great sword masters. What is more important is their will. They would not want to be distracted by Devil Fruit ability, otherwise it would be a denial and doubt of their own Swordsmanship will.
But neither the real Shiryu nor Sig was such a pure swordsman!
This is why Sig could freely imitate Swordsmanship without revealing any flaws... Otherwise, even if Sig's strength improved several levels, it would be difficult for him to imitate Hawk Eyes. It's not a matter of strength, but rather that his Swordsmanship will would be easily exposed.
Shiryu himself wasn't a Swordsmanship who pursued pure swordsmanship; in the original work, he had already eaten Devil Fruit — the Clear-Clear Fruit of Absalom, one of Moria's subordinates!
This is why Moria's fate was unknown when Sig traveled through time—because Absalom "disappeared" after being attacked by the Blackbeard Pirates, and Moria angrily went to Hachinosu to demand an explanation, only to be ambushed by the invisible Shiryu...
The "Clear-Clear Fruit" is undoubtedly Devil Fruit ability that doesn't require much development; combined with one's original fighting power, it can exert a tremendous effect.
Whether you're Martial Arts or a swordsman, having an extra ability to hide will ultimately make you stronger... provided you don't feel that it hinders the purity of your Martial Arts or Swordsmanship.
Since Sig had the opportunity to make an outrageous demand, he directly asked for Mythical Zoan Fruit. After discovering the subtle conflict between the Thunder-Thunder Demon and the Prison Demon, Sig decided to choose Zoan for his third fruit, and since it was Zoan, Mythical Zoan would be even better!
Although Sig can only take the third Devil Fruit when he reaches Sequence 4, it would be good to get it ahead of time, especially since it would make the Navy work for free... It's like the enemy loses a Devil Fruit while he gains one, double the fun.
As soon as Sig finished speaking, he realized that Sengoku really did have some in stock, because he hesitated for a moment, but then made a decision without refusing.
"Okay, you can go and rest first... The fruit you requested will be delivered to your room later. However, it's a fruit that's not even listed in the encyclopedia. All we can confirm is that it's Mythical Zoan of the Dog-Dog Fruit. Before you leave, eat it first, and then demonstrate its basic abilities to me. I won't reveal it to anyone, but I will write it into the confidential encyclopedia." Sengoku agreed.
Upon hearing this, Shiryu showed a hint of delight—asking for Mythical Zoan Fruit also suited Shiryu's interests. After all, Zoan Devil Fruit generally provide significant physical enhancements, allowing swordsmen to directly increase their strength, unlike Logia -type fruits which conflict with Swordsmanship, and Paramecia fruits whose effects are unpredictable...
Mythical Zoan are generally considered to be "stronger Zoan Devil Fruit".
Of course, this isn't necessarily the case in reality. It's just that they are "rareer Zoan Devil Fruit." Some Mythical Zoan offer less benefit to the body, with their physical enhancements being inferior to Ancient Zoan or even to the most powerful beasts among the Common Zoan types. However, they will definitely have special abilities, so they generally won't "lose out."
Sig had been paying close attention to Sengoku's emotional changes...
You can tell that Sengoku wasn't lying—it really is a fruit that isn't in the illustrated guide!
The reason why we can distinguish between the Dog-Dog Fruit and the Mythical Zoan is quite simple: all Dog-Dog Fruit are Devil Fruit based on the shape of a persimmon, and the spiral cloud pattern of the Mythical Zoan is different from that of ordinary fruits!
For example, Yamato's Okuchi no Makami Fruit is shaped like a persimmon, but it only has cloud patterns around the stem, which is clearly different from ordinary fruits.
Therefore, based on the shape of the fruit and the cloud-like patterns, it can be determined that it is the Dog-Dog Fruit, Mythical Zoan. However, the specific type of fruit still needs to Record after someone eats it.
However, while it's true that Sengoku made Shiryu eat it and then demonstrated it to him partly to Record in the encyclopedia, that wasn't the whole reason...
Another reason is to ensure that Shiryu doesn't have any other Devil Fruit ability, and... to ensure that Shiryu Devil Fruit ability in the future—eating a Devil Fruit would not only mean increased strength, but also make it easier to subdue him with Seastone!
If Shiryu any other ideas, it will be easier to clean up the mess later.
Sig pretended not to notice and left Sengoku's office, just in time to see Vice Admiral Tsuru walking over.
Even when facing this senior strategist, "Shiryu" showed no intention of giving way, walking directly past the frail old woman. As their figures passed each other, he glanced down at her, his arrogance fully displayed...
