The fastest sword!

Using his Haki, Masa quickly protected Carina, but for him, Moria's aura was nothing. Nevertheless, there was no doubt that he was surprised by Moria, who could release such a powerful aura that could impact and dominate the minds of others. 

Yet, did Moria think that he was the only one who could use this aura of domination?

Bang! 

At that moment, Masa also burst out a powerful aura that caused everyone to pass out directly due to intense fear. 

Even Brook, who was quite powerful, fell down to an intense fear that came from the impact caused by Masa. 

Yes, while the Armament Haki and Observation Haki needed to be learned, the Supreme King Haki was inborn, and naturally, for someone like Masa, who dared to kill a World Noble, the noble of this world, and admiral, one of the strongest within the Marines, for a woman, how could he not awaken it? 

Or, rather, if he didn't awaken it, he would be a dork. 

Masa might wish to live a peaceful life, but for those who destroyed his peace, even if they were the highest beings, then he wouldn't hesitate to kill all of them! 

Yet, at this moment, he might not know that the world had chosen him as the candidate for the supreme ruler. 

Nevertheless, if there was a reason why he didn't use this ability, it was because he lacked someone to teach him, so with his current skill of the Supreme King Haki, what he could do was dominate the minds of those small fries, and it was simply meaningless to those who were strong.

More importantly, all the people around him were either those he controlled or Carina's previously, so with the exception of the mental simulation using Supreme King Haki, it would be his first time using this ability. 

Still, as their auras met each other, the space and the air cracked, yet soon, Moria's aura was suppressed, which caused Masa to chuckle before he stopped his Supreme King Haki. 

"I will go first." 

"Win." 

Carina directly kissed Masa, which made him speechless. 

"What's with that gaze? Shouldn't you feel happy being kissed by a beautiful woman like me?" Carina asked with a cute pout. 

"...kissing before a battle will bring a bad omen." 

"Huh? Really? Where did you learn it?" Carina looked at him in doubt. 

"Well, whatever, I will go first." 

Masa shook his head, then turned into a light to move toward Moria. 

Meanwhile, Carina, who was still in the treasure room, wondered whether kissing before a battle would really bring a bad omen. 

Nevertheless, as Masa appeared in front of Moria, he smiled and said in a relaxed manner, "Oh, you look so powerful now." 

"SHUT UP, BRAT! DO YOU THINK YOU CAN LOOK DOWN ON ME NOW?!" 

Unlike before, Moria had become stronger, returning to the past, his peak when he fought Kaido in the past, but even so, he knew as he had been down for so long, his body was no longer at a peak, but it wasn't a problem. 

Yet, at the same time, Moria was even more furious at this young man, who thought that he could beat him so easily. 

'Moreover, that aura!' 

Moria almost exploded, thinking at how Masa looked down on him by stopping his Supreme King Haki before it completely overwhelmed him, bringing him down as if Masa had given him the mercy of the strong! 

'I'm going to make you pay for looking down on me!' 

"Go on." 

Masa folded his arms and gave Moria a chance to grow stronger so his fight wouldn't be boring. "You are going to make me regret it, right? Then, show me." 

"...." 

"I WILL KILL YOU, BRAAAAT!!!" 

Moria burst his aura once again as he used his Kage Kage no Mi to the limit! 

"SHADOW'S ASGARD!" 

As his voice fell, a powerful aura once again swept everyone, and at the same time, all the shadows on the zombies disappeared and all moved into Moria's body! 

Yes, Moria's body absorbed all the shadows and gathered all of them within his body, strengthening his body further towards its peak when he fought Kaido or even more! 

His desperation, fear, and wish to protect his living comrades brought his strength even further to the limit, something that Moria had never felt before, something that made him above many and even became the king of this world! 

As he grew stronger, his body also grew larger, so large that it towered toward the sky like an ancient giant that he had kept within his ship. 

Still, if Moria knew that Masa had devoured that giant, there was no doubt that he would become even stronger due to his anger! 

 "Kishishishishi!" 

His voice was so loud that it could make anyone deaf and shook the ground like an earthquake, yet, compared to his voice, his body had become a powerful monster that could destroy everything. 

"You will pay for your arrogance, boy! Do you think that you can do whatever you want just because you are a Logia? This sea isn't so simple! Your arrogance will make you regret it now!" 

Moria raised his hands high, and at the same time, something dark started to clad his fists like black gloves. 

"Oh, you can use a Haki?" 

"ARE YOU SURPRISED? DON'T LOOK DOWN ON ME! THIS TIME I WILL DEFEAT YOU! 

Yet, facing Moria, who was about to smash him with his giant fists that were covered in Armament Haki, Masa was as calm as ever. His mind was clear, yet instead of using his Pika Pika no Mi, he held the Shushui on his side, holding it in the way of a battojutsu or sword-drawing technique, also known as Iaijutsu. 

"I will get a little serious, then." 

Blue Beast. 

This was Masa's nickname from Mahouka, yet he got this nickname because of the new magic that he created, known as "Coulomb's Sword." 

Yet, Masa needed CAD (Casting Assistance Device) to use this magic, so he couldn't use it. 

Still, with that magic name, it was clear that Masa from Mahouka was a swordsman. 

Yes, while the world of Mahouka was the world of magic and science, the magic swordsman also existed, and Masa was one of them. Moreover, he was also one of the strongest due to being known as the fastest. 

Yet, even if he couldn't use that magic known as the "Coulomb's Sword" due to how complicated it was and the need to use CAD, as Masa had devoured the Mink-Tribe, he gained better control over his bio-electricity and used his other sword technique, which made him known as the fastest swordsman in the world. 

More importantly, due to the improvement of his physical ability and after devouring Ryoma, his sword technique became even stronger and more refined than before. 

Unlike in the world of Mahouka, the swordsman in the world of One Piece had a special existence; using only their physical ability, technique, and will, they could grow into a feared existence that even reached one of the strongest. 

At the same time, similar to Moria, Masa's sword was covered in a dark color, yet with a slightly crimson color Haki. Yes, Masa used his Armament Haki to increase his attack power further. 

However, unlike Moria, Masa's sword, arms, and hands were also covered in lightning. 

As Moria used everything he had, Masa also decided to respect Moria and used everything he had. 

"Let me show you my fastest sword." 

Charging his sheathed blade with lightning, Masa created a magnetic field around both the blade and sheath, creating an ultra-electromagnetic battojutsu, the fastest sword technique in the world, and its name was—

"Raikiri." 

As Moria smashed his fists, Masa unleashed his blade.

Slash!

'I lose again...' 

As Moria thought within his heart, an intense light overwhelmed him, and all of a sudden, Masa was already behind him, standing calmly as the sound of his sheathed blade sounded. 

At that moment, a sonic boom exploded, and everything was cut down. 

BOOOOOOOOOOOOOOOOOOOOOOOOOMMMMMM!!!!

Whether it was Carina, Brook, or those who remained conscious, they could only open their mouths and eyes wide as they saw the dark fog that covered the Florian Triangle in darkness split into half, causing the light from the outside to enter and basked his presence as Moria was defeated.
