"So you made it back to South Korea?"

"Yeah, but that bastard Gun said he forgot something and left me on the plane alone!!! Since he's not here, my work practically doubled!!!!"

As he was sitting inside of his dojo, Bang was on the phone with Goo. After checking to see if the weapon genius made it back safely, Bang was prepared to hang up the phone. However, Goo had something on his mind he needed to discuss.

"Fist of Exploding Heart, Liberation. During one of the days we trained, Nagisa used that move against me. That was your original fighting style that you wanted to bury along with your past self. Why did you teach it to Nagisa?"

"I didn't teach him."

".......are you serious?"

"After he told me about how he experienced using the Demon Slayer Mark, which he inherited from his mother's genes, we tried to help him awaken it again. However, one day, he noticed how fast his heart was beating and timed the impact of his attacks with his heart. Soon he shifted his training from using the mark again to turning the discovery he made into a weapon in his arsenal of hand-to-hand combat techniques."

"In your attempts to bury your past and help him awaken the mark, Nagisa accidentally invented a new form of martial arts for himself from his perspective. With his ability to copy, plus that other form he has on top of his training with you, that would mean....."

"I don't know if it'll happen in his normal state, but if it were Ultra Instinct, then i'm sure of it. He'll copy my power back when I was in my prime. With his potential, if given the opportunity to use it with his life on the line, i'm sure he might even surpass me in my prime."

~In Yokohama~
"It's really you, Tomioka Nagisa!"

Kuusetsu screamed in joy as she flew towards Nagisa with her claws out. After he escaped her, she promised herself that she would make sure to keep the boy to herself and mate with him as intended. However, while she was mid flight, she noticed Nagisa was already in front of her as his attack was already set in motion.

Kuusetsu began to cough up blood as she felt Nagisa's fist striking her chest with such extreme force, it almost felt like her heart would explode from the impact. When she looked at Nagisa, she saw how the boy's heart was explosively pulsing in time with the impact of his attack.

"Dammit. You think you can beat.....a god....."

"I don't need to think about it."

Those were the first words Nagisa spoke ever since his fight with Daniel. Suddenly, Kuusetsu found herself trapped in a torrent of punches as Nagisa kept punching her in the gut relentlessly. His bones and limbs broken, his flesh feeling like it was getting torn the more he forced himself to keep fighting. It would be hell for anyone else. But if it's only dealing with pain, if it's only a matter of powering through, then Tomioka Nagisa can keep moving. The moment he landed that last attack and felt his heart beat explosively, Nagisa was already out of the Ultra Instinct state. Right now, Nagisa was moving through sheer willpower alone.

"Naon....."

"Koko........"

"And this last one is for Mira!"

He was beginning to reach his limit. No, it was more accurate to say he already reached it a long time ago. It took Nagisa everything he had to not pass out on the spot. However, when he glanced behind him, he looked at Kyouka and Yuuki who were concentrating on their own attack.

Soon Yuuki disappeared into the sword as Nagisa and Kyouka glanced at each other. The two of them nodded as if coming to an agreement as Nagisa kicked Kuusetsu towards Kyouka's direction as the chief took a stance with her grip on her sword growing tighter. As Kuusetsu saw where she was heading, she spun her body as she sharpened her claws, ready to rip Kyouka apart.

"It's time to submit."

Soon Kuusetsu began to bleed profusely as she felt her strength dropping at a drastic rate. While this happened, she slowly turned around as she heard the sound of footsteps getting closer and closer to her. By the time she turned around she saw Nagisa walking towards her. The god of thunder tried to run away from him as fast as she could, but without Naon and Koko absorbed, she soon returned to her original form.

"Kuusetsu.........it's time for your divine punishment."

This was all the strength he had left that he could muster. Nagisa knew that this copy would be the final attack he would make in this fight. Right now, he was copying someone so strong, he accidentally killed his opponent in a Muay Thai match. Nagisa placed both of his hands on the ground as he got into a running position, putting all of his strength into his legs as Kuusetsu ran.

"Brekdak Forbidden Technique Number Five......"

"....... ORGAN PIERCER!!!!!"

Before Kuusetsu realized it, Nagisa's knee had went through her back as her internal organs were destroyed. Soon, Kuusetsu's body began to disintegrate until nothing more was left of her. The God of Thunder known as Kuusetsu was finally slain as her body was merely reduced to smoke.

Before the smoke cleared, Aoba grabbed Naon and Koko and escaped through a nearby sewer drain. Seeing this, Tenka purposely missed her attacks to make it seem like Aoba dodged it and got away from the group so the rest of the corps wouldn't arouse suspicion.

"Looks like you took down the god!!!!!"

When Yuuki realized this and slightly relaxed, he noticed how his consciousness was fading away. Soon Yuuki was lying on the ground as he was knocked out. Seeing this, Kyouka rushed over to Yuuki's side. Meanwhile, Tenka walked over to Nagisa as the boy was standing still.

"You did great Nagisa. You really have grown."

".........."

Tenka was met with no answer. As Tobera walked over to Nagisa, she was surprised to see Nagisa's body. Some of his flesh torn, his limbs and bones broken. The boy killed almost every shuuki that was released in Yokohama, managed to fight a monster with strength that was unparalleled, and landed the final blow onto Kuusetsu. The man who did all this, the man who took the most damage, didn't take a knee even when he was unconscious.
