Clash of Odama Rasengans

"Lion's Roar."

While Kakashi and the others were talking, the battle inside the arena had already changed. Natsuhi, who was engaged in taijutsu contest with Naruto, suddenly let out a low roar. The purple chakra that had disappeared behind her burst out again, transforming into a predatory lion that lunged directly at Naruto.

"Don't underestimate me, Rasengan!" Naruto had already learned the one-handed Rasengan over a year ago. He didn't need to enter Sage Mode to effortlessly use the jutsu, just like Jiraiya and the Fourth Hokage. In an instant, a Rasengan formed in his hand, smashing the lion. But soon, he was astonished.

It was because while Naruto was dealing with the lion, Natsuhi had already used Body Flicker Jutsu to appear behind him. She also had a Rasengan in her hand, which struck his back, sending him flying.

"That's a Rasengan!" Ino exclaimed. By now, she knew that it was a technique developed by the Fourth Hokage. How could such a difficult and high-level ninjutsu be mastered by almost everyone around Ryoha?

"It's nothing surprising. I learned that jutsu over two years ago," Natsuhi said, not even bothering to look at Naruto, who was sent flying by the Rasengan. Instead, she looked towards the other side.

Sure enough, at the spot Natsuhi was looking at, with a soft popping sound and a puff of smoke, another Naruto walked out. To determine whether the Shadow Clone Jutsu used by Naruto was the real body or a clone, the most effective way was to rely on intuition and experience. Even Ryoha's Eternal Mangekyo Sharingan would find it difficult to distinguish between the real one and the fake. Otherwise, he wouldn't have deceived Kakuzu.

Now Natsuhi had to rely on her combat experience and intuition to judge. It made her realize that the Naruto who was just attacked was just a Shadow Clone; he had been replaced at some point.

"How did you learn it?" Naruto couldn't help but curse himself for asking such a foolish question. It was needless to say that Ryoha taught her. Naruto clearly remembered that scene when Ryoha fought Jiraiya for the first time, and he "learned" the Rasengan just by glancing at Jiraiya's.

"Of course, it was the one over there who taught me. And not only this technique, but I also know the Odama Rasengan," Natsuhi said. Unlike the Naruto in the original work, she didn't use any tricks. She practiced the Rasengan step by step. Using the Rasengan with one hand was no problem, and the Odama Rasengan with one hand was also feasible for her.

"Does that mean she knows everything Naruto knows?" Shikamaru felt that Naruto was in danger now. It seemed like the opponent knew all the Rasengan attacks that Naruto excelled in, and her proficiency surpassed Naruto's.

Naruto could use the Rasengan with one hand without entering Sage Mode, but the Odama Rasengan required assistance from another person. On the other hand, Natsuhi could use the Odama Rasengan with just one person. It was evident that Natsuhi had put in more effort in this aspect compared to Naruto.

"Sakura, if Naruto can't handle it, you and Ino should quickly use medical ninjutsu on him," Shikamaru analyzed the situation and said to Sakura and Ino.

Sakura and Ino didn't want to directly confront Ryoha, nor could they do it. But if it was to heal their current teammate and comrade, Naruto, they would be more than willing. After all, they were still members of Konoha, and as medical ninjas, it was their duty and responsibility to heal their comrades.

"I understand," Ino and Sakura nodded in agreement.

"Odama Rasengan!" Uzumaki Naruto was not willing to back down either. Although he couldn't create it alone, summoning a shadow clone was not a difficult task for him. At most, it was just a bit troublesome. Two massive Odama Rasengan collided and clashed in mid-air.

"Bang!"

A force kept expanding until a gigantic semicircular sphere with a diameter close to a hundred meters emerged. However, if one considered the other half of the light sphere continuously pressing down, it formed a huge spherical shape rather than a semicircle.

"What a battle between monsters." Shikamaru couldn't help but sigh. If someone taught him this technique, he could learn it without any problem due to his intelligence. However, it would be useless to try to execute it.

Because this jutsu was powerful, but it also depended on the user. Just relying on Shikamaru's Shadow Imitation Jutsu, which consumed so much chakra, and his limited chakra reserves, using a chakra-consuming technique like Rasengan, was simply courting death. Such scenario was tasteless and a waste for Shikamaru.

"No way, Shikamaru, it's because you didn't take chakra refining seriously before. Besides, for the Nara clan, it's normal to have a moderate amount of chakra, not too much and not too little. Their body are not suitable for using this jutsu."

Kakashi nodded. Jutsus also had their users. Many people might be able to learn Rasengan, but among those who learned it, very few could actually use it in combat. Rasengan had tremendous power and potential, but it also consumed a significant amount of chakra.

If it weren't for Natsuhi's training in the gravity chamber, coupled with the nutrient she drank, which was created jointly by Tsunade and Bulma, her physical and spiritual energy would have directly increased, and the extracted chakra quality would continuously improve. Moreover, she currently had no side effects from the Star training.

If Natsuhi hadn't completely absorbed the energy of the star that would give her a massive amount of chakra reserve, she wouldn't use this jutsu. Even Ryoha wouldn't teach her this technique because using this jutsu with little chakra in battle would be suicidal.

Ryoha realized that Natsuhi's training in the gravity chamber and complete absorption of the star's energy had resulted in an astonishing amount of chakra within her body. Additionally, both Natsuhi and Naruto possessed Wind Nature Transformation, which is why he entrusted Rasengan to her. Otherwise, he would have chosen another jutsu for her instead of Rasengan.

"She's so formidable. How did she become so much stronger compared to over two years ago?" Naruto was well aware that his current self was much stronger than himself from over two years ago. Back then, he had defeated Natsuhi quite easily. But today, even though he had become much stronger, he couldn't defeat her. He had even used the Odama Rasengan, and they were still evenly matched. It was no wonder he was so astonished.
