"Thunder Prison!"
Relying on the Lightning Flame and Color of Observation Haki, Enel covered the ground with Lightning Flame and then sent it soaring into the sky, creating an area that resembled a prison. In this area, the enemy's movement would be predicted to a certain extent through Color of Observation Haki infused into the Lightning Flame.
This technique was actually very similar to the Sutra that he had developed using Rumble-Rumble Fruit's ability, except that it required Lightning Flame to cover a large area. It greatly enhanced his sensory abilities, but it also had a certain drawback: it was quite draining.
So, he had to quickly kill Opera and Counter. Otherwise, he'd run out of gas and fell prey to them!
Clear Rain Island, Ugetsu Dojo.
As Ugetsu Asari oversaw Kuina's training, he nodded and said, "Very good, you've become proficient in Eleven Form of Shigure Soen Ryu. Next, you should familiarize yourself with the Two-Sword Style. Although you've mastered them, the Twelfth From requires two swords. As for the ultimate technique, you'll need to master Dying Will Flame first. Once you've mastered all Shigure Soen Ryu, you can start creating your own Shigure Soen Ryu. However, that will be a long process, but I believe that with your talent, you can do it, Kuina."
Ugetsu acknowledged Kuina's talent in swordsmanship, and even though she still had ways to go compared to him, Kuina's talent in swordsmanship was already top-notch.
She still had the chance to become the greatest swordsman in the future even against Squalo and Mihawk, whom Ugetsu Asari had defeated before.
"This is all thanks to your guidance!" Kuina smiled.
"Shigure Soen Ryu depends entirely on individual talent. Without sufficient talent, one cannot become the successor of this style."
Ugetsu said as he stood up. He picked up Enma and Three Irregular Swords and said, "Kuina, continue your training. I have some matters to attend to."
Just now, he had sensed that someone with ill intentions had set foot on Clear Rain Island, and all the members Vongola Family on the island had been ordered by Ugetsu to protect the civilians.
So, he was on his own in the upcoming battle!
"Are you going to fight, Master? If so, please take me with you. Although I'm not powerful enough right now, I won't drag you down, Master!"
Kuina immediately saw through Ugetsu. As a member of Vongola Family, she also wanted to step up and did her part when the Family was in danger. She was also quite strong. With her Rain Flame, Shigure Soen Ryu, and her Wado Ichimonji, she was invincible among kids her age.
During their time in Green Bit earlier, she had also demonstrated how strong she was. Even high-bounty pirates couldn't withstand the blade in her hand!
"Stand down, Kuina! You shall not participate in this battle. Unless I fall, no one needs to get involved in this battle!"
Ugetsu's gaze instantly became sharp, and his tone became solemn. "I am the Rain Guardian of Vongola Family. If I'm guarding this island, that means no one is allowed to be harmed before I fall! This is my battle alone, and even Primo will agree with my idea. Do you understand?"
Along with these words, he also emitted a unique aura. While most people exuded a fierce and violent aura, Ugetsu was different...
Cold, quiet, but there was a storm beneath it. Just like the rain brewing in the sky, you'll only know how cold it was once it fell!
"I understand, Master!" Kuina nodded and stopped asking.
With a slight smile on her lips, she watched as Ugetsu walk outside.
After walking for about ten minutes, he found a suitable place for battle—a clear ground with a small river flowing down from the high mountains nearby. He stood there and waited in silence as he closed his eyes.
As time passed, a group of people with hundreds of wild beasts approached the area. These beasts were different from those attacking Blue Iron Island and White Stone Island. Each of them gave off a much stronger aura. Each of them was on par with Rear Admirals, and there were 10 of them. They were the A-Class Beasts!
The approaching people were also some of the most skilled people of the Charlotte Family!
Charlotte Cadenza, Charlotte Cabaletta, Charlotte Amande, and Charlotte Effilee...
Although their appearance was unsightly, their strength was the real deal. Especially Charlotte Amande, the third daughter of the Charlotte Family, was a formidable female swordsman. She wielded the famous sword "Shirauo", with a hilt shaped like fish scales and a hilt shaped like a pure white fish.
She was the one in charge of attacking Clear Rain Island, but it was unclear why Big Mom and Shiki had not sent the stronger combatants to attack an island guarded by Ugetsu Asari.
"If you leave now, I will spare you."
At this moment, Ugetsu reopened his eyes, and his gaze slowly swept over all the enemies.
"Vongola Family Rain Guardian, Ugetsu Asari..."
Amande had already locked onto her opponent. "You are well aware that we won't withdraw because the victor of this battle will be Big Mom Pirates. Besides, I also want to test the strength of the world's greatest swordsman!"
