'I shouldn't have done that...'
While everyone was in awe due to Shinra being able to knock out Bellamy, who had reached a maximum speed and impact with his technique, Spring Hopper, Shinra also had to admit that he had underestimated the physical ability of Bellamy.
No matter how weak Bellamy was and even if he was defeated by Luffy in the original with just a single punch, he was still a pirate with a high bounty of 58 million berries!
At the same time, Luffy was a pirate with 100 million berries!
Also, how could Shinra think to compare his physical ability with a strange creature known as Luffy?
He was lucky that his arm didn't break as he made a last-minute judgment by enhancing his fist with a chakra and using the Removal ability, which broke the limiter on his body, further strengthening his physical ability to increase his tolerance and defense.
While he had the Water Stream Rock Smashing Fist, it didn't mean that he could reflect the attack of someone without caring about the strength of his opponents. The strong people in the One Piece series each of their attacks could easily destroy several buildings, which was different from the world of Kengan, where they could only crack the exterior of a hard object and even if they could destroy something, it was because they aimed the weak point of the object when they attacked instead of making a reckless attack on anything.
So, facing Bellamy, who had enhanced his speed to the limit with the Bane Bane no Mi, he had become like a human bullet, and his attack would smash a normal person into a meat pulp.
Regardless of his victory, this also made Shinra feel sober, thinking that it was fortunate for him to go to the world of One Piece instead of returning to the world of Naruto. If he returned to the world of Naruto, he would be killed mercilessly without knowing when.
The martial arts in the world of Kengan might be impressive, but they had a lot of limitations since even Bang, the One Punch Man, who was the founder of the Water Stream Rock Smashing fist, couldn't deflect or redirect Saitama's punch.
'In the end, it's become like this, huh?'
In front of the overwhelming power, everything was meaningless.
However, it didn't mean that his visit to the world of Kengan was meaningless since he gained many experiences and talents in martial arts.
'If I use the martial arts of Kengan, with the physical ability of the world of One Piece and the power of the Devil Fruit, what will happen?'
When he thought so, his mind became hot as he grabbed Bellamy and Sarquiss away, leaving everyone dumbfounded. While he had said many things, frankly, it wasn't so difficult to defeat Bellamy and Sarquiss despite having quite a high bounty.
Sarquiss aside, as he was defeated before he could do anything, Bellamy's defeat was normal, especially given his rapid movements, which ignored the possibility that his enemy might counter him.
As Bellamy moved so fast in a straight line, Shinra just used his Aiki, redirected the force that was brought by Bellamy, and smashed Bellamy with all of his might!
If he had to describe it, it was like a boxing counter technique where one boxer launched a fierce punch, but was countered by the other.
Counter was, without a doubt, the most powerful technique, as the damage caused by this technique didn't come solely from the boxer's fist, but also from the momentum of the opponent, which made this technique even more deadly.
However, Shinra had to admit that Bellamy's technique was powerful against a weakling. Still, it was also quite reckless since if Bellamy moved at the highest speed after bouncing around and hit a steel pillar or a sharp spear, one could easily imagine a gruesome scene that had happened to Bellamy.
Broken bones, being pierced, or his body was torn.
Yet, this also made him wonder whether Bane Bane no Mi was really that weak.
More or less, the Bane Bane no Mi resembled the Gomu Gomu no Mi that was eaten by Luffy.
Whatever Luffy could do, Bellamy, who had eaten the Bane Bane no Mi, could do more or less the same.
Bouncing, stretching their limbs, or even being almost immune to the physical ability, what the Gomu Gomu no Mi could do, was able to be done by the Bane Bane no Mi.
More importantly, the main purpose of the spring was to absorb and store energy, which led to the creation of a suspension to absorb shock waves on the carriage and soften the ride.
It could be said that both Luffy and Bellamy had the elastic quality that made them more or less immune to the blunt attack, yet somehow, Bellamy was beaten by Luffy in a single punch.
Why did all of this happen?
Shinra could only say that it was because Bellamy wasn't part of the D family, nor did he have a father who worked as the leader of the revolutionary army, a grandfather who worked as a hero marine, or a mentor who was a Four Emperor.
Or, in just a simple term, Bellamy had no talent, especially when Shinra felt like the potential of the Bane Bane no Mi was higher as a spring was made of a metal, so while Luffy, whose rubber body, was weak against a sharp object, Bane Bane no Mi should be able to defend against the sharp object and wasn't so fragile as it was made of a metal.
Still, no matter what, Shinra decided to try the Eye of Usurp on Sarquiss and Bellamy.
The two of them had been defeated, so their resistance was low, if not non-existent.
The Eye of Usurpation might be powerful, but if the opponent wasn't incapacitated, they could resist. The ability of the Mangekyou Sharingan wasn't omnipotent, and if their target had strong resistance, willpower, or was simply strong, their unique ability would be rendered meaningless.
So, the best way to use his ability was when his target lost their resistance, when they were weak, or when they died.
If they lost their resistance aside or if they died aside, if they were weak, but a protagonist of the story, Shinra felt like his ability would be blocked by a certain force such as luck, fate, or simply a protagonist's aura would make it hard for him to usurp everyone of this opponent.
Regardless of whether it was Sarquiss or Bellamy, neither was the protagonist, and Shinra could usurp their everything without worry. As he walked toward the forest, away from the crowd, hidden, his eyes changed into those of Mangekyou Sharingan. He stared at the two, usurping everything before turning them into an old, fragile thing, like an empty husk.
Yet, while the two were in disbelief and shock, Shinra felt a boundless energy enter his body, and at the same time—
Boing!
His arm turned into that of a spring, which made him feel a little uneasy, but he turned his eyes in a certain direction before his arm stretched so far that it smashed into the gigantic tree, tearing it apart.
BOOOOOOOOOMMMMMM!!!
Boing!
As his fist returned, Shinra felt that this ability was more interesting than he had imagined it to be and thought to learn it further, but before that, he had to take down the one who had been tailing him, following, and spying on him first.
