It was only for a second. The moment the two of them locked eyes with each other, both Ren and Nagisa were already in front of each other. Suddenly Ren flew over Nagisa's body as she saw the boy slash at the ground. When she saw what happened, she saw a large slash mark engraved into the ground.

"The power, speed, experience, and technique of Goo Kim, Uzen Kyouka, along with the original breath user and Riu Myouga's deceased husband. He copied all of them at once and applied those copies into a single action. He's at the threshold of mastery. The mastery of both swordsmanship and his talent for copying."

Just as Ren thought this, Nagisa was already in front of her as his fist was an inch away from her head. The chief smiled as she was suddenly out of Nagisa's path as his punch caused the boulder behind her to become nothing but powder. Ren was lost in thought when she witnessed this as she was floating nearby.

"The speed and accuracy of both Bomb and Bang. The power of Gun and the fighting genius, Tom Lee. Finally, the technique and experience of the Muay Thai Champion, Brekdak all combined into one punch."

Dangerous. That was the one word that came to mind when describing Nagisa in this state. Suddenly the boy threw Kyouka's katana at Ren, only for the chief to fly into the air. However, the chief was shocked to see a wire attached to the hilt of the katana.

When Nagisa pulled upon it, the katana was suddenly being swung in the air as it was honing in on Ren. The chief merely used her ability as the symbol in her eyes changed. As she kicked towards Nagisa, a large shockwave was sent flying towards the boy as he crashed through a boulder.

"Not only that, but even his adaptability is still intact. If he were to do all this while having full control........ interesting. You keep getting more and more interesting, Nagisa."

When Ren thought this, she saw the boy standing back up. As he held Kyouka's katana tightly, Nagisa took a high stance as Ren's eyes widen in shock. Right now, at this very moment, Ren was already within his range. Not only was he using this particular breath style, he was also combining it with another form of combat.

Just as Ren took a slight step back, Nagisa was already in front of her as he swung his blade horizontally. Ren was quick to fly upwards, but she noticed that Nagisa had performed a feint as he dropped the katana from his right hand into his left. As Nagisa jumped, he spun his body as he tried to perform a diagonal slash upon the Head Commander. Ren swiftly flew behind him, but her eyes widen in shock as he dropped the katana back into his right hand and struck her gut with the pommel of the blade. Before she could react, Nagisa turned around and performed a final downward slash as Ren was sent crashing into the ground.

"Each attack was filled with the intent to kill. He releases the blade and uses it with his other hand the moment he sees the slightest movement that indicates my escape. He didn't plan consecutive feints. He simply reacted fast enough to the point they looked like planned feints, but he was simply reacting in real time. Plus each strike was aimed at my vitals too. If I was a second off, i'd be in danger."

She had to test this. Despite how easily she can resolve this situation, Ren has to test it. Both the limits of Nagisa's potential and the frightening rate of his adaptability in combat. Right now, for the first time, Ren Yamashiro was being thrilled in battle by both her curiosity and her opponent's strength.

Suddenly Nagisa began to take a deep breath as he held the katana tightly in his hand. Soon he began to slowly take a step forward. As soon as his foot touched the ground, Nagisa was already in front of Ren as his blade was already swung. However, his eyes slightly widen in shock as the sword snapped as Ren had already swung her leg and launched a shockwave at him.

"Come on, Nagi. Show me just how strong you are!"

"......."

Just as Ren was continuously launching shockwaves at Nagisa, the boy was trying his best to nullify her attacks with Dead Calm. While he managed to stop attacks aimed at his vitals, Ren's attacks were numerous and powerful while also being launched at blinding speed. Slowly but surely, Nagisa's defenses were growing weaker.

Suddenly the boy threw the broken katana in his hand at the commander. Just as Ren flew into the air, Nagisa had already jumped as he slammed his right foot on top of her head as she crashed into the ground. As Nagisa was falling, he was spinning his body to build momentum as he had his right hand in the hand-blade position. Just as his hand was about to make contact with her neck, Ren placed her right index finger on the boy's head.

"Sorry, but that's too dangerous. Don't go trying to kill your owner, Mad Dog."

As soon as Ren said this, Nagisa was suddenly teleported high into the air. Soon Ren was charging up a lot of energy into her right leg. Seeing this, Nagisa began to clench his right fist. At this moment, he was copying five people at once as he was prepared to attack.

All five of these monsterous fighters. Their strength, speed, flexibility, experience. Even down to the very ways their muscles contracted. Right now, Nagisa was copying these traits to the point it can be seen as if he was mastering their ways of fighting all at once. Just as he was close to Ren, the boy punched with all his might as Ren released a giant shockwave directly at Nagisa.

As the two attacks clashed, everything around them was blown away and tearing apart. An enormous crater forming on the ground as if it was hit by an asteroid as dust filled the air. By the time the air cleared, it revealed Ren on her back as she was conscious but coughing up a little blood. Right beside her, Nagisa was unconscious as the mark was no longer on his body. Right now, this battle of humanity's strongest ended in a draw.

"I wonder....just what did Medusa inject you with to make you go insane like thi-"

When Ren's eyes fell upon Nagisa, her eyes widen in shock. While Nagisa was knocked out and heavily damaged, she noticed something off about the boy. Instead of a deep crimson color, the normal color that one would expect when seeing a wounded person.

Tomioka Nagisa's blood was pitch-black.
