"What should we do? Well, it depends on you guys. The only time-space Ninjutsu I know is the Flying Thunder God, but it can't teleport us from one dimension to another." Nagasawa shrugged.
Kamui was an absurdly strong ability, allowing teleportation between the real world and the Kamui dimension. However, Kaguya's Amenominaka was even crazier.
Apart from the main space, there were five other Dimensions: Lava, Ice, Supergravity, Sand, and Acid.
Nagasawa's spatial ability was only Flying Thunder God Technique. In this situation, he found himself powerless.
Fortunately, perhaps since Kaguya didn't see Kakashi as a threat and Obito being in critical condition, Kaguya ignored them, leaving them along with Nagasawa in the Lava Dimension.
Kakashi or Obito would be useless on their own because it required both of their Sharingan to synchronise with Kaguya's Amenominaka and travel to the other Kaguya's dimensions.
"Us?" Kakashi was puzzled for a moment. He didn't understand why Nagasawa said that. Setting Obito aside, he didn't have the ability to travel into other people's dimensions.
"Kakashi, take out my eyes and use it." Obito was now exceptionally clear-headed that he immediately understood what Nagasawa meant in an instant.
"Cough, the Mangekyō Sharingan's true power can only be harnessed with both eyes. My Mangekyō Sharingan's ability is also a time-space ability. Maybe it can synchronise with this dimension." Obito explained softly as he coughed a couple of times.
If he had the strength, Obito would have gouged out his own eyes to save time.
"That's right, that's what I mean. Time is running out; we must quickly find Naruto and Sasuke." Nagasawa quickly stated.
Looking at Obito's exhausted face, Kakashi hesitated for a moment. Then, he swiftly gouge out Obito's Mangekyō Sharingan and pressed it onto his own eye.
The moment the Mangekyō Sharingan was transplanted, immense power immediately coursed from the eyes throughout Kakashi's body. He had never felt this much power before.
However, he quickly noticed that Obito became even weaker, as if he would die at any moment.
"Obito, you..." Kakashi's expression became complicated.
Although Kakashi had never possessed a complete Mangekyō Sharingan, he was certain that even a complete Mangekyō Sharingan wouldn't grant this much power. He had seen people with complete Mangekyō Sharingan, and they didn't exhibit such strength.
The truth was that Obito also stored his remaining Six Paths power in the Mangekyō Sharingan he gave to Kakashi as well.
"Don't waste any more time. The Kakashi I know is an outstanding Shinobi who doesn't hesitate in crucial moments," Obito said softly.
It wasn't that Obito deliberately spoke softly; he simply had no strength left to speak.
Being severely injured from Nagasawa's attack, Obito also used Samsara of Heavenly Life Technique in his weakened state. Moreover, his Rinnegan and the Ten-Tails within him were taken away, so his body had long given up.
If Obito didn't attain Six Paths Sage Mode before and received a crazy amount of Six Paths Chakra, he would have died long ago due to the overwhelming injuries.
It was thanks to the Six Paths Chakra that Obito barely held on until now. And now, he passed the Six Paths Chakra to Kakashi. Without this Chakra, the result was clear.
Kakashi began to recall their days in the Academy.
However, Kakashi knew that now wasn't the time to get all nostalgic and sentimental. They had to quickly find Naruto and Sasuke to stop Kaguya's plan.
"Rin, I'm coming! Let's meet again in another world. Kakashi is too annoying, so we don't want him around anytime soon." Obito thought deep down. Remembering Rin's cheerful and energetic smile left a smile on his lips as well. Then, he closed his eyes.
This time, he should be able to barely win against Kakashi.
"Obito, this time, we will fight side by side! I will use your power to bring us victory!" Kakashi shouted upon seeing Obito slowly close his eyes.
Kakashi took a deep breath and placed Naruto's body in Kamui dimension.
"Can you do it?" Nagasawa asked Kakashi.
"No problem. I sensed it. There are a total of five, no, six!"
"Can you specifically sense where Naruto and Sasuke are?" Nagasawa continued to ask.
Kakashi shook his head and said, "No, I can only sense those dimensions. Moreover, opening those dimensions requires a massive amount of Chakra. If it's just me, I'd say that three is my limit."
Nagasawa frowned slightly. There were a total of six dimensions, excluding the Lava Dimension they were in. If Kakashi could only open three, that meant there was a risk that they wouldn't encounter any of them.
"Moreover, this is because the Mangekyō Sharingan that Obito gave me just now contains Six Paths Chakra. Under normal circumstances, opening one dimension should be my limit," Kakashi added.
After a moment of thought, Nagasawa said, "Alright, here's the plan. I'll transfer my Chakra to you so you can open those dimensions."
"But won't you be at a disadvantage during the fight later?" Kakashi asked.
Although the Chakra Obito gave him was potent, Kakashi believed it probably still couldn't match Nagasawa's strength. After all, Obito was defeated by Nagasawa, and this was just a portion of Obito's Chakra.
If Nagasawa's strength was compromised to help Kakashi, it would be like putting a cart before the horse.
"You don't need to worry about that. I've taken it into account, and it shouldn't affect me," Nagasawa assured.
After some consideration, Nagasawa decided to activate Supernova Mode during the battle against Kaguya. Kaguya was the final obstacle, and even if he died immediately after defeating her, it wouldn't matter. So, sacrificing himself was an acceptable strategy.
However, using Supernova Mode was a painful experience, as it burned away his life force. But he was willing to take that risk to face Kaguya.
Seeing Nagasawa's determination, Kakashi nodded and focused on synchronising Kamui with Kaguya's Dimensions.
Nagasawa placed his hand on Kakashi's shoulder, transferring his Chakra to him.
Kakashi's Mangekyō Sharingan shook violently, and the space in front of them began to distort. Soon, the two disappeared from the Lava Dimension.
Pa-ta!
As soon as Nagasawa and Kakashi landed, a towering yellow-green wave was about to hit them.
Nagasawa dished out a flaming compressed air blade aura that evaporated the massive wave. Then, he carried Kakashi to a nearby rock using Geppo.
Kakashi tossed his kunai into the yellow-green sea.
bzz, bzz, bzz!
Instantly, Kakashi's kunai was corroded.
"That's one dangerous acid," Kakashi remarked, looking somewhat surprised at how fast his carefully crafted Kunai corroded. Falling into this liquid was no better than falling into the lava in the previous dimension.
"Can you do it again right away? Naruto and Sasuke are not here." Nagasawa scanned the surroundings with his sensory abilities and realized that there was no one else in this dimension apart from them.
Kakashi nodded. Although this was taxing for him, there was no time to rest. They had to quickly catch up with Naruto and Sasuke.
Once again, Nagasawa placed his hand on Kakashi's shoulder and the portal to another dimension was opened.
This world differed from the previous two; it stretched endlessly with nothing but sand dunes and desert as far as they could see.
However, as Nagasawa scanned the surrounding, he felt relieved.
This time, luck was on their side as they encountered signs of life.
In the midst of the desert, Nagasawa sensed Sasuke's presence.
After awakening Rinnegan, Sasuke also possessed sensory abilities and quickly sensed Nagasawa and Kakashi's presence, so he rushed towards them.
"How did you guys get here? Is it Kaguya's doing?" Sasuke asked in confusion.
Ever since being teleported to the Desert Dimension, he had been wandering for a while, unable to find a way out.
Nagasawa shook his head and replied, "We came here on our own. Obito's Mangekyō Sharingan can synchronise with Kaguya's worlds, allowing us to travel between them."
Hearing this, Sasuke's face displayed both surprise and joy.
"Then let's hurry and meet up with Naruto. Since neither of us has encountered Kaguya, she must be currently fighting Naruto," Sasuke quickly suggested.
Nagasawa nodded and once again transferred his Chakra into Kakashi.
He had to admit that traveling from one Kaguya's Dimension to another consumed a significant amount of Chakra. Even for Nagasawa, it felt a bit overwhelming. Doing it four times would likely deplete all of his Chakra. The system didn't pass him the Chakra from his Yin Seal. Otherwise, it would have made a significant difference.
This time, the trio arrived in a world with extremely strong gravity. Being caught off guard, Kakashi and Sasuke were immediately overwhelmed by the immense gravity, while only Nagasawa remained standing.
"Darn it, what is this place?" Sasuke didn't seem pleased, not because he was embarrassed after he fell, but because he realized the horror of the Gravitational Dimension.
In this space, let alone dodging attacks, even standing was a difficult task.
If Kaguya was immune to the gravity in this dimension, then this dimension would undoubtedly be a nightmare for them.
Kakashi was in an even worse state than Sasuke. Repetitive use of Mangekyō Sharingan imposed placed immense strain on his body. On top of that the gravity force in this dimension was so high that it made things worse for him.
Fortunately, Nagasawa could use a little bit of Medical Ninjutsu and immediately used Mystical Palm Technique to provide some healing to Kakashi.
"Haa!" Kakashi panted heavily, his gaze was firm, enduring the pain to once again activate the Mangekyō Sharingan.
He had witnessed Obito being crushed by boulders, and Rin's body pierced by his Chidori. Even if others thought he was an outstanding Shinobi, Kakashi felt like a useless person, who wallowed in despair all the time.
But this time, Kakashi really didn't want to be useless.
Even someone like him should have a moment of glory.
Space twisted for a moment, and the three disappeared within the Gravity Dimension.
Boom!
As soon as they entered the new world, a loud explosion reached their ears.
Nagasawa looked towards the direction of the explosion, where hundreds of Naruto were floating in the air, fending off Kaguya.
This was the Ice Dimension, with nothing but ice as far as the eye could see.
Kaguya gathered powerful Chakra on both palms and unleashed sequence of countless fists, instantly annihilating dozens of Naruto.
However, for the hundreds of Naruto present, losing a few dozen was just a fraction.
One Naruto after another began to condense Rasengan and rushed towards Kaguya.
Facing so many Rasengans, even Kaguya didn't want to take them head-on. She teleported away using Yomotsu Hirasaka to avoid their attacks.
Seeing Kaguya disappear, Naruto initially planned to go after and see if he could enter Kaguya's portal. However, upon sensing Nagasawa and Sasuke's presence, he quickly headed towards them.
"Hmph, you're doing pretty well, Naruto. I was afraid you wouldn't last long," Sasuke casually turned a compliment into a sarcastic remark.
"Don't be ridiculous. Right now, I'm super strong," Naruto said with an upset look on his face.
"Be careful and don't let your guard down. Kaguya could show up at any moment," Nagasawa reminded them.
Upon learning that they had reunited, Kaguya would certainly make her move.
As soon as Nagasawa finished speaking, a black portal appeared, and Kaguya appeared next to Naruto.
Crack! Crack!
Using the ice from that dimension, Kaguya instantly created a hundred-meter-high ice block, freezing herself and Nagasawa and others together.
However, Kaguya was, after all, the master of the dimension. She could easily use the Yomotsu Hirasaka to escape from the ice.
The ice in Kaguya's Dimension was clearly colder and more potent. As strong as Naruto was, he could only slowly break the ice by grinding it with the Truth-Seeking Balls.
But Kaguya wouldn't just watch quietly. She raised her hand, and the Black Zetsu hidden in her sleeve lunged towards Naruto and Sasuke.
However, Kaguya had miscalculated this time. Ice was something Nagasawa feared the least as his Sun Breathing was constantly active!
Hoo! Hoo!
Powerful golden flames erupted from Nagasawa, instantly thawing the ice.
Sensing the overwhelming golden flames, Black Zetsu decisively retreated into Kaguya's sleeve.
"Mother, I think you should isolate that fire user from them." Black Zetsu quickly suggested.
Just as Kaguya was about to use Yomotsu Hirasaka to take Nagasawa away, she suddenly felt a stinging pain in her abdomen.
Boom!
Kaguya was sent flying and slammed into an iceberg.
She looked at Nagasawa in disbelief. This shouldn't be possible. How did that person suddenly become so fast? He was so fast that she couldn't even react in time.
"Kaguya, from now on, your opponent is me, Fourth Hokage Fujiawara Nagasawa. I'll give you a taste of humanity's power. Get ready to be purged by the Will of Fire." Nagasawa pointed a sword made of golden flames at Kaguya.
