"In Sage Mode, my overall combat power soared by ten to twenty times. You are no match for me. Originally, I planned to use this move when fighting Ryoha, but I didn't expect you to force me to use it. However, it doesn't matter because the battle will end in an instant."
After entering Sage Mode, Naruto's ninjutsu and physical abilities are enhanced several dozen times. It can be said that among all the ninjutsu techniques that rapidly boost strength in the ninja world, this is the one with the highest increase. In just five minutes, Naruto, who was originally at the Elite Jonin level, possesses the combat power of a Kage-level powerhouse. His ninjutsu got a massive power-up in a short amount of time.
"Natsuhi, don't absorb his Sage Mode chakra." Ryoha warned Natsuhi. He didn't want her to turn into stone, so he made sure to tell her in advance, lest she had the opportunity to absorb Naruto's chakra in Sage Mode.
"What?" Natsuhi was a bit puzzled, but it was not the time for questions. Naruto had already made his move. His speed suddenly increased several dozen times, and he used the Body Flicker jutsu to instantly appear in front of Natsuhi. He threw a direct, simple, yet highly effective punch.
"Bang!"
In a critical moment, Natsuhi used the Mysterious Peacock Method to transform her chakra into a fan and blocked the punch from Naruto. However, Naruto's attack was not just a simple punch. He also used the Sage Art: Frog Kumite, a technique that mobilizes the surrounding natural energy as part of the user's attack.
"Bang!"
Naruto's taijutsus were noticeably stronger by several dozen times, and his power was greater. One punch shattered Natsuhi's purple chakra and, at the same time, he used the Frog Kumite, directly striking Natsuhi's face with natural energy, sending her flying.
"It's over, Sage Art: Odama Rasengan." At the same time, a Shadow Clone that also entered Sage Mode appeared above Natsuhi, and a three-meter-wide Odama Rasengan directly blasted her to the ground, causing a deep crater about two meters deep and more than ten meters in diameter to appear.
"He was amazing. In the original story, he used Sage Mode, unleashed the Eight-Tails, and had the help of the Toad Clan to face Pain in Konoha. He was barely defeated even though Pain had used the Shinra Tensei, a jutsu that consumes a massive amount of chakra. Now, he is even stronger than he was at that time. He's so powerful on his own. If he continues to develop, when Pain attacks Konoha, Naruto will probably be even stronger."
Ryoha calmly watched as Natsuhi was destroyed by the Odama Rasengan, not showing any emotion or even making a move. This change made Kakashi and the others extremely worried. Had Ryoha become heartless to the point of not caring about the people around him? Or perhaps Natsuhi was completely unharmed? Whichever it was, Kakashi couldn't help but feel concerned.
"I told you to be careful. Sage Mode is one of the most powerful technique I've seen among all the techniques that rapidly boost one's strength in a short amount of time. It's a technique that can challenge opponents of a higher level." Ryoha suddenly broke the silence, but he felt that something was not quite right before he could finish his sentence. "I almost forgot to bring you out."
The space in front of Ryoha suddenly distorted, and a person emerged from it. It was Natsuhi, who had just been attacked by the Odama Rasengan. At the critical moment, Ryoha used Space-Time Ninjutsu to send her to another dimension, a space similar to the one where Karin and Sasuke were transported by Tobi. It was a safe dimension without any danger, so Ryoha could confidently send Natsuhi there.
"Did you teleport her to another place?" Kakashi thought of his Kamui, but Kamui was different from ordinary space-time transfer. Kamui was a technique used for killing, not for safely transferring someone. On the contrary, if someone was transferred by Kamui, it meant certain death. One was for spatial transfer (safely moving someone away), and the other was for space distortion and consumption, able to twist and remove any part of a person's body, including their head. It could be said to be a killer Mangekyo Sharingan technique. Therefore, Kakashi didn't dare to use Kamui to transfer his comrades away because anyone transferred by Kamui had never survived.
"You could say that, but I just moved her to a different dimension. How was today's battle? What did you gain?" Ryoha's main concern was not victory or defeat but the gains after each battle.
"It's not bad. I have gained a new understanding of the practical application of jutsu," Natsuhi smiled, looking slightly disheveled from the impact of the explosion and the smoke, but in reality, she was not injured.
"Mystical Palm." Ryoha reached out and tapped Natsuhi's cheek, which had been struck by natural energy moments ago. The slightly swollen cheek completely recovered in the blink of an eye, returning to its previous state as if it had never been hit.
"He even learned the Mystical Palm? What kind of jutsu does he not know?" Yamato exclaimed in astonishment, stunned. After all, Mystical Palm was an advanced medical ninjutsu. Even in Konohagakure, which had the highest level of medical ninjutsu among the Five Great Countries, there were very few medical ninjas who had mastered this technique. Yet, Ryoha, who was proficient in so many different types of jutsu, had managed to cultivate medical ninjutsu to such a level.
"Natsuhi, is there anything else you need to do?" Ryoha originally intended to personally test the extent of his newly fused Mangekyo Sharingan, but by observing the battle with his eyes, he had already roughly discovered the significant improvements in his insight and amplification of genjutsu.
If we were to make a comparison, Ryoha's newly-fused Mangekyo Sharingan was several times stronger compared to the previous Inverted Cross Mangekyo.
This was only referring to the abilities of insight, genjutsu amplification, and similar capabilities. There were still some special abilities of the eyes that hadn't been taken into account.
"It seems like there's nothing else. Didn't you say you wanted to test your eyes? Why don't you just go?" Natsuhi stared at Ryoha's eyes, which had returned to their white background with black irises, with a hint of confusion in her voice.
"There's no need. I already got a general idea of it when I used them to watch your battle," Ryoha smiled and was about to leave, but Naruto called out to him.
"Ryoha, this is the power I cultivated after losing the Nine Tails. This is the power I possess! Let's have a fight. I might not necessarily lose to you now."
It was unclear whether Naruto felt somewhat arrogant after winning against Natsuhi or if he believed that he was invincible after activating Sage Mode.
