Immediately the word left his mouth an enormous yellow spiraling orb appeared on his palm causing a vacuum of air around him. The enormous orb blocked out the sky and brightened up the entire area. It was like a mini sun in the sky.
"How?" Dante stared appalled at the spiraling Yellow orb in the sky.
"What is that? Answer me?!" Mundus demanded in rage. He could no longer understand what was going on anymore. How dare them come into his world and try to humiliate him. Him? The great demon king Mundus.
Dante also couldn't comprehend what was going on. He felt like he was just getting to know Naruto for the first time. He could feel the power behind that enormous orb in Naruto's hand.
"YOUR DEFEAT!" Naruto roared before bringing the rasengan down on Mundus. Mundus threw caution to the wind when he saw the attack coming down on him. He started attacking the glowing orb with all he had but it didn't slow down
"THIS IS FOR EVERYTHING!" Naruto roared before the rasengan connected with Mundus causing him to roar out in pain. The rasengan grind him into the lava pit before exploding creating a giant crater with Mundus nowhere to be seen.
Immediately Mundus disappeared the space they were in shattered returning them back to the pale white room.
Naruto form also reverted back to normal as he fell to his knees, exhausted. His breathing became labored as if he had the weight of the world on his shoulders.
'What is this? Why do I feel out of breath?'
'It's probably because it was your first time using that much chakra.' The nine tails voice rang in his head surprising him.
'Kyubi? But how?'
'Don't be so surprised. With the seal gone, you and I can communicate through our thoughts. Moreover, you won't be able to take that form for a while since you have completely exhausted your chakra reserves.'
'But that shouldn't be possible. From my parents memories the uzumaki clan have a very large chakra reserve' Naruto frowned.
'That was in the elemental nation where the world operates based on chakra. This worlds concept is different' The kyubi understood how the kid was feeling. But after watching his fight with the demon king he came to a conclusion. Which was the fact that this world doesn't operate in chakra. And since chakra doesn't exist in this world the consumption of chakra was very high.
"Naruto, are you okay?" Dante asked Naruto when he saw him unmoving. He could see the exhaustion on his face. That attack must have taken a huge toll on him.
"I'm fine" Naruto said as he stood back up to his feet. His gaze wandered the room before landing on the form of Trish lying on the ground a few feet in front of them.
When Dante saw where Naruto was looking he said. "I owe her an apology. I shouldn't have said those bad things to her. If it wasn't for her we wouldn't have been able to defeat Mundus. She protected me just like my mother did. She was more human than I ever thought"
By the time he finished speaking he had already reached her side. He took off his pendant and place in on her chest before stabbing Sparda in the ground beside her.
"Thank you Trish. If we ever meet again. I promise to show you around the human world" Naruto said even though he thought it might never happen.
After Naruto said his goodbyes he turned around only to see Dante staring at him with a contemplating look on his face.
"What?"
"What exactly happened back there? I thought you were dead" Dante asked the question that had been rolling around his mind ever since he saw Naruto return from the land of the dead.
"I thought so too. But somehow I ended up somewhere else and met my parents."
"Your parents? As in the real deal?" Dante asked surprised. He has heard of Naruto's story on multiple occasions. So he was certain of the fact that Naruto didn't know his real parents. It was something that used to sadden him back then, but thanks to his and lady's effort he was able to overcome it.
So how wouldn't he be surprised now that he was suddenly being told that Naruto met his parents out of the blue.
"Were they the one who saved you?"
"No" Naruto shook his head. Then with a complicated expression said. " The nine tailed fox saved me."
"The fox?!" Now that was another surprise. When they heard first found out that Naruto could harness a bit of the fox power they had tried to no avail to come into contact with the fox. It was as if it was avoiding them.
After trying for three years straight they had given up on contacting the infamous nine tailed fox.
"Yes. The power I used before was his. This was also a present from him" Naruto said as he held out purgatory for Dante to see.
Dante whistled as he examined the demonic looking sword. "Now that's a sword worthy of it name. But I don't think Lady is going to be happy with what you did to her birthday present" Dante added as an after thought
However before he could question Naruto some more the whole place started to quake violently.
"What is going on?"
"The whole place must be coming down, now that Mundus is no longer here to sustain it. We should get going before it is too late"
"But what about Trish? We can't just leave her here."
"She is gone Naruto. There is nothing more we can do for her. Now let's go!" Dante shouted when he saw Naruto unmoving.
'Damn it' Naruto felt bitter in his heart. Steeling his heart he cast one last look at Trish before running out of the room with Dante.
The two of them retraced their steps back to the large room with the heart to get to the room all the to the area where the Living Cave started. Like before there is a single Frost in this room which Naruto dealt with using purgatory. Afterwards, the two of them made their way out through the white membrane on the other end, which led them back to the room where they defeated the Nightmare.
The quaking never stopped. It was almost as if the whole place was going to come down on their heads at anytime.
Naruto and Dante continued to make their way through the underworld killing every demon they came into contact with. The more they fought the more Naruto began to understand just how powerful the new version of purgatory was.
It wasn't an exaggeration to call it overpowered. He could now better channel the kyubi chakra through the blade since it contains a part of his soul. He now had access to it nine tailed cloak form but it consumed a lot of stamina. So the kyubi warned him to only use up to six tails of it chakra worth for now to get accustomed to it.
They stepped into a red magic circle on the floor and returned back to the mirror world cathedral. After moving down a corridor they reached the area with the gateway to the underworld. By the side of it was the eyeball platform which they used to return back to the normal cathedral.
Immediately they appeared inside the cathedral they were attacked by the Marionettes in the Cathedral which they quickly destroyed before proceeding out the door to the long hallway.
In the long hallway they fought a pair of Blades. Once they were defeated, they proceeded through a door into a workshop with the biplane.
"That's the plane from before" Naruto exclaimed when he saw the biplane. "Do you think it still works?"
"Only one way to find out" Dante replied as they moved towards the biplane.
However when they walked halfway into the room the floor sudden collapsed underneath them dumping them into a sewer.
"Gross" Naruto shouted in disgust after he picked himself up from the dirty water. "Now I smell like piss and shit"
"The island won't last much longer as it is" Dante said as he looked up the hole they fell down.
"You don't have to worry since you won't be leaving this island." A dark voice echoed around them prompting them too turn towards the end of the room where a white portal had mysteriously appeared.
Mundus burst out of the portal with a deafening roar. The whole place shook as his huge form hit the ground. He no longer had that majestic look to him. He crawled forward with his hands as the statue's majestic exterior gradually fell apart the revealing the chaotic mass of flesh underneath.
"The gate has been opened. The two of you will not be getting away. This is where you will die"
"Mundus? How are you still alive?! Naruto couldn't believe his eyes when he saw the king of the underworld standing before them. He had been the one that dealt the last blow to Munda, so he knew for certain that he should be dead.
"You!" Mundus eyes narrowed when he saw Naruto standing beside Dante. "Child, I owe you for what you done to me. I will make sure to repay you by extinguishing your soul from existence!" Mundus said before shooting a green beam at Naruto.
"As if" Naruto shouted as he deflected the beam with purgatory and sent it crashing into a wall far away.
"Such insolence!" Mundus roared when he saw how his attack was easily deflected.
Naruto ignored mundus rant as he turned to Dante and said. "Let's end this once and for all, Dante"
"You took the words right out of my mouth" Dante smiled as he summoned Alastor. He then pointed it at Mundus and said. "Prepare to receive a proper burial Mundus"
"Die!"
Mundus fired multiple green beams at them only for them to vanish on the spot leaving afterimages behind.
The two of them attacked Mundus with all faster than he could react. But after a while they noticed that they weren't doing any damage to him.
"What's the matter? Here your powers are weak" Although deformed Mundus still ridiculed their futile attempt to kill him.
'Kyubi, how about now?' Naruto urged the nine tails as their normal attacks were no longer doing damage to him.
'I still haven't gathered enough chakra yet, kid. Be patient'
'I don't have enough time to be patient!'
Dante was already out of breathe and options when he heard a voice reaching out to him. "Dante you can do it. You'll be okay"
"What?!...mo…mother"
