The anglerfish jumped forward and slashed his sword.

Kai took another look at the sword and realized it wasn't a normal sword. He further confirmed it by striking the sword with his Super Sonic Sword, which didn't even leave a single scratch.

"Hmm…" He narrowed his eyes and said, "I see. Someone's skin, huh."

The anglerfish didn't say anything, but that smug smile of his already told him pretty much the answer.

Before he released another sword, the clam charged at him with his shield in front. He planned to ram him so the anglerfish could slash him.

Kai took a deep breath, raised his sword and waited for the clam to arrive. This obviously grabbed their attention as they raised their vision, leaving a blind spot coming from below. It was at this time Kai raised his left foot and kicked the clam's shield or more likely its shell with all his might.

On his boot were two magic circles. The first magic circle was below his shoes, where it generated the power, while the other one was covering his shoes to direct the Sound Wave to go to a certain area he designated.

This was the result of his training in the Emulda Kalan. He named this magic as…

"Echo Thruster."

Despite his naming sense, the power was a real deal. The generated Sonic Boom released all its might straight to the shield.

A shock wave flew out of the clam's body as if the Sound Wave just went through his body. Even the clam couldn't help but scream when his hand felt the excruciating pain inflicted by the Sound Wave before he got launched several meters away.

"Guah!"

"Oi, Hatker!" The anglerfish's body shuddered as he turned around to see his teammate.

Unfortunately for him, an action like this wasn't something Kai would pass on. He used his second sword to strike the blade from above until the anglerfish's sword stuck on the ground.

"Not good." The anglerfish widened his eyes and saw Kai raise his other sword to strike him.

When the Kai struck his body, the blade only cracked a bit of the anglerfish's hard skin.

"I worried for nothing, huh." The anglerfish smirked, knowing Kai wouldn't be able to kill him in one stroke.

However, a magic circle appeared on Kai's handle as the sword vibrated once more, creating a loud ringing sound.

"Sonokinetic Blade."

Ding.

In that instant, Kai's sword continued on its path, sliding on the anglerfish's body before the anglerfish suddenly flew away.

"Guah!" Just like the clam, the anglerfish felt extreme pain on his chest before he saw his hard skin was cracked and some even started bleeding. At the same time, Kai's attack actually released a kind of crescent-shaped sword wave that launched him into the air.

He realized Kai managed to trap his own Sound Wave and formed this crescent-shaped energy that looked like it was surrounded by the wind.

But this sharp Sound Wave was none other than his Sonic Boom. He simply directed the Sonic Boom forward.

Trees upon trees fell down as the anglerfish's body destroyed their trunks on its way. He continued to fly for two seconds before falling down to the ground, rolling a few times until he stopped.

Kai smiled and looked at their conditions. If this were him from the past, he wouldn't be able to fight against these two at all. He would only be suppressed while searching for a way to escape. This would also lead Roselyn and Sofia into danger, so he was glad he managed to learn many things from Arba.

Kai smiled and took a deep breath, feeling a bit restless since he hadn't gotten used to controlling the direction of his Sound Wave. It took a toll on his mind, so he planned to end this fight quickly.

"What just happened?" The clam rose from the ground and looked at Kai, who seemed to be able to repel them. No, they were the ones who couldn't stand against him.

"You… What did you do?" The anglerfish, Yuba, stood up and roared, coming to him with a serious expression. Although the damage was only on his physical body, it was still shocking for Kai to defeat them in one exchange.

"After fighting you all for so long, don't you think it's time for me to step up my game and beat you this time? I can't afford to lose continuously or rely on my teammates when your ability is restricted on the land after all." Kai smirked and pointed his swords to them. "Now, let's see what you guys have to offer. I alone am enough to defeat you."

The anglerfish gritted his teeth and jumped forward since he thought he just underestimated Kai earlier. As long as he was careful, there was no way Kai would be able to defeat him.

"I will let you know our real strength!" Yuba ran to Kai with his sword in the front, planning to thrust him.

However, Hatker shouted in shock because he could see it from his position. "Yuba. Watch out!"

Yuba widened his eyes and turned to the left, finding Roselyn coming to him. She swung her sword at Yuba's sword to stop him.

Yuba obviously didn't care about her since her attack would probably be lighter than Kai. And yes, he was right. Her power couldn't be compared to Kai, but it was different when eight metal spider legs emerged from the small machinery on her back.

Four of the legs stabbed the ground while the other four grabbed Yuba's body. When their swords clashed, the four legs on the ground stabilized and pulled to gather more power from the ground to stop him while the other legs tried to launch him backward.

This way, Roselyn managed to stop Yuba's momentum in one move.

Suddenly, another presence emerged behind his back. It was none other than Sofia.

She placed her hand on Yuba's back and summoned a Magic Circle.

"Circulation Ice Magic, Splash."

Ice crystals emerged from his chest and he got pushed forward again.

After stopping him, Roselyn had gained a bit of distance from him, so she ran forward and struck his body as she passed him.

"Authority Blade."

The wind that covered her blade burst out and tried to open the crack Kai left behind and some spots even started to bleed.

However, Roselyn dropped to her knees as she spat a mouthful of blood.

"Gah."

"Haha, I am someone from the deepest part of the sea. Do you think your ice is cold enough for me?" He laughed before turning around and spinning his elbow to hit Sofia on the face.

Seeing this, Sofia raised her hand and activated her exoskeleton to repel that arm. Unfortunately for her, Yuba's power was too strong for her to handle and she ended up getting launched to a nearby tree.

Still, as one would expect from the stronger Sofia and Roselyn, Yuba needed to fall to the ground too, because of their damage.

"Kh… What is this wound?" He thought Roselyn's attack didn't connect, but when he saw blood coming out of his body, He had another perspective.

To wipe the blood, he used his hand to cover the wound first, but he soon realized his hand felt numb before finding another ice crystal.

"!!!" He just realized what the two women were doing and thought, 'Did she purposely let me hit her to attack me with this kind of technique?'

After observing the development, Kai leaped to Yuba to deal with him, but Hatker quickly appeared before him.

"You're not going anywhere," shouted Hatker while raising his two shields. Before Kai did anything, the clam changed its color.

'Magic?' Kai narrowed his eyes.

The clam turned his body as well as the shield into a glistening surface. The color was black with some white that seemed to be light that reflected on the metallic black surface.

"Pearl!" Kai immediately realized that clams produce pearls. Although it was only for a few species, it was enough for him to understand where his power came from.

Hatker smirked and ran forward, trying to ram Kai with that huge shield. "I am far stronger right now. Let's see whether you can destroy my defense…"

"You talk too much." Kai snorted and struck the shield with both swords. "Sonokinetic Blade."

The swords vibrated at the same time and created a cross crescent-shaped Sound Wave that pushed Hatker several meters back.

Hatker was still showing his smirk as he tried to fight this violent power that knew no bounds. He said, "No wonder you can launch Yuba that far. Unfortunately for you, this is not enough to destroy me."

Hatker pushed the Sound Wave back until it dispersed.

"It's—" Hatker wanted to say something after destroying Kai's attack, but Kai himself had appeared in front of him and sent another kick to him, using the same magic.

"Sound Amplification." Kai used all his strength into this kick and launched him far away. He simply couldn't contain that kick since he barely destroyed Kai's Sound Wave.

"Kh!" Hatker gritted his teeth, landed on the ground safely, and looked at Kai with a hateful expression. He seemed to be angry that Kai stopped him earlier since he had bragged about his good defense.

At the same time, Yuba couldn't do anything since Sofia and Roselyn locked him in that position, not allowing him to escape or help Hatker.

"You are still far weaker than that turtle I have seen." Kai shook his head in disappointment and pointed his blade at Hatker. "I may be enough to kill both of you, but I by no means plan to do it. So, I hope you can fight me for a bit longer."
