Bane Bane no Mi.
This is an ability that allows him to turn his limbs or his body into that of a spring.
What is the use of the spring?
The purpose of the spring was to absorb and store energy, so no matter how his opponents tried to hit him, all of the energy that they released from their fists, kicks, and other attacks would be absorbed inside his body, and Shinra could use that energy to attack his opponents by releasing it, which would enhance the damage that came from his physical attacks.
Among all the fighters in the tournament, Wakatsuki Takeshi, one of the strongest fighters in the tournament, who was quite a shame that wasn't Shinra's opponent, had a technique that resembled a spring mechanism.
The Blast Core.
This was a technique where Wakatsuki compressed all of his muscles, like compressing a spring to the limit before unleashing them.
Since Shinra had the ability of Bane Bane no Mi, he could do the same, and even better, but naturally, this ability wasn't omnipotent, since a certain limit of how much energy his spring-like body could absorb existed, but as this limit was high, and no one in the world of Kengan could break this limit of his, he felt like he should be more or less immune to the blunt type of weapons since their forces, shockwaves, kinetic energy, momentum, and everything else would be absorbed by the spring.
Yet, while there was a limit, this limit could be improved by training his physical ability further, and frankly, this Devil Fruit was even better than that of Gomu Gomu no Mi since unlike Gomu Gomu no Mi, which weakness was a sharp weapon, the Bane Bane no Mi had no such weakness since a spring could also be made from a metal.
Not only could this body of his absorb and be practically immune to blunt-type attacks, but his body was also as strong as metal, which made this Devil Fruit give the user the highest defense.
If Gomu Gomu no Mi didn't develop into Nika Nika no Mi, then Shinra would say that Bane Bane no Mi was the advanced version of the Gomu Gomu no Mi since it could do everything that the Gomu Gomu no Mi could, yet still could defend against the sharp weapon as a spring made of metal.
It could be said that as Shinra had eaten this Devil Fruit, he had become one with the highest defense since no one could break his spring-like body, and when they tried to attack him, he would return their attack twice or more.
Whether it was Kanoh Agito or Tokita Ohma, his two next opponents, they were just defeated by him, and Shinra became the champion of the Kengan Anhilation Tournament, which made Shion become the chairman of the Kengan Association.
Still, while he had become the most powerful in the world of Kengan, he didn't overestimate himself, especially when in the world of One Piece and Naruto, many monsters existed.
"Should I train in the world of One Piece?"
Shinra hesitated since he could tell that even if he went to the world of One Piece, he was sure that he couldn't use the Eye of Usurp on those powerful figures, and if he used that ability, he was afraid that his eye would become blind.
The Bane Bane no Mi might be good, and he also had the potential of a unique human in the world of One Piece, but once again, even if he worked hard for several years, he wouldn't become an omnipotent being that could.
Rubbing his eyes helplessly, he knew that he had to make his eyes into Eternal Mangekyou Sharingan.
'Just one is enough.'
No, he didn't have to have two Eternal Mangekyou Sharingan, but just one was enough, especially the "Eye of Usurp."
As for the Eye of Beyond, it should be okay to use it several times.
"Should I go back to the world of Naruto?"
However, when he thought of the only people who owned the Mangekyou Sharigan, he hesitated.
Itachi, Obito, and Danzo.
Of the three, while Shinra didn't think that he would lose, his victory would be quite ugly since those three weren't weak.
Itachi was obvious as he was the strongest Uchiha Clan ninja in this generation.
Obito had the ability to escape to another space.
Danzo, although he wasn't as strong as the two, had many subordinates who would throw their lives to protect him, and he could also report to Sarutobi and his gang. This meant that Shinra might have to fight hundreds of elite ninjas, which was troublesome.
Besides those three, Shinra wasn't sure whether there were other owners of the Mangekyou Sharingan. This made him hesitate to go to the World of Naruto, as he feared that if he made the wrong move, he would waste the chance to use his Eye of Beyond.
At the same time, Shinra felt that his strength wasn't that omnipotent, even though he was fully capable of releasing the secret power of Mangekyou Sharigan, Susanoo, which might be as mighty as the Nine-Tailed Fox that ravaged the Konoha, since if he used it, he was sure that his eyes would become blind and he would lose his Mangekyou Sharingan.
So, among all the choices, Shinra knew that the best way for him was to go to a new world.
Still, before that—
"Let's get the nuclear bomb first."
Oh, no, he had to remind his women first.
"You are going to train?!"
Shion and Karura were dumbfounded, but Mikoto was calm and just asked, "When did you plan to go back?"
"I don't know."
Shinra wasn't sure how long he would be in another world, but hopefully, he could return soon, depending on the gains he could make in this new world. "But I will go back before our child is born."
He would have to go back at least before his first child was born.
"It's fine. You don't have to worry. I will be waiting."
This world was comfortable, and it was so nice that sometimes it made them think that it was better to live in this world than return to the world of Naruto.
However, while it was enjoyable that he could have fun with many, it was impossible for him to swallow everything and just let the world of Naruto move in a way that was original, especially when those who had harmed him could have a good ending.
So, he had to leave, get stronger, and return.
So, after the tournament, Shinra directly left and went to the Korean peninsula to pick up several weapons for his preparations in the next world, which naturally, caused many to look for him since as he had won the tournament so easily, he had become the strongest fighter in the Kengan Match if not the world, which made many strong fighters in the world wish to gain his title, but unfortunately before they could do anything, they died as his trace completely vanished from this world.
"So, this is a new world..."
As Shinra was in the new world, unexpectedly, this world wasn't much different from the world of Kengan, especially when the neighborhood was quite modern, but—
BOOOOOOOOOOOOMMMMMMMM!!!!
As a loud explosion happened, and a sound of destruction echoed, a cry of a little girl was heard.
"Mama! Mama! Mama!"
"Run away... please..."
"No, I want to go with Mama!"
"I beg you..."
Shinra, who had quickly come upon hearing the noise, was dumbfounded, for what he saw wasn't just a mother and a daughter in crisis, but also a gigantic, creepy monster that stared at the two, seemingly ready to devour them.
"...."
Standing at the top of the rooftop of one of the random houses in the neighborhood, Shinra was in a daze for a moment. "...what the heck is this world?"
