The Soviet Union
The United States of America
China
India

Finally, Naruto found Japan, which actually used the same written language as him. With his chakra he could kind of understand what was in people's hearts and negate the need for language, but the fact was that chakra didn't give him the magical ability to understand written language as well as spoken language. That was why he needed to find a place with a written language that was as close to his own as possible, to help him transfer his own language into the current one.

Japan used Kanji too, so he found himself a home.

He spent 1 day resting and recovering from his injuries, before getting a bite to each and searching the world for a place to stay.

"A devil! There is a devil in the center of the mall!"

'A devil... hmmmm... if the spoken language is exactly the same, then that isn't something good.' Naruto hummed to himself. He didn't know what the hell a mall was, but it had to be big enough for something to be at the center of it. Naruto saw people running away from something in one direction, so he started to walk quickly in that direction.

He had seen something demonic looking in the frozen forests of the Soviet Union, so maybe this was something related to that. He hadn't bothered picking a fight with it, since he was used to weird animals from his home world.

"Gahahahahaaaaa! Tasty, tasty humans!"

"Eeeeeew." Naruto recoiled in digust when he saw a creature that was made up a ton of electric eels. It was close to 20 feet tall, and it's body was super slippery looking. It had a long neck that had a bulge in it, and with a human leg sticking out of it's mouth, Naruto knew instantly that it wasn't a good guy.

The fact Naruto didn't run away from it, meant that he became the creature's next target without even provoking it. The leech demon got down on flipper hands and feet, and charged at Naruto with it's mouth opening up wide, and revealing a second set of jaws inside of it's jaws.

It was slow.

It moved at such a slow speed, to Naruto once the creature got close enough, it went practically in super slow motion. His reaction times were far beyond the speed the creature had. Naruto leaned to the side, and he punched the back of the monster's head. There was a squishy thud, a crack, and the creature fell face forward, completely dead. Naruto didn't need to feel bad about killing a man eating monster, so he didn't even blink at it.

So this was a mall?

A lot of stores, currently abandoned.

-10 Minutes Later-

"Looking sharp." Naruto looked at himself in the store mirror. He had been wearing his war torn clothes since he came to this world, and they just weren't in a condition to keep wearing. So he found himself a plain white shirt, unlike the clothes from his world where he could get a spiral this had no spiral on it. He felt naked without a jacket though, so he found himself a brown leather jacket. Finally, he was wearing blue jeans and flip flops for shoes, since he couldn't find any combat sandles like from his world.

No orange clothes in this store.

Naruto still appreciated how good he looked in the outfit, and there was nobody around to make him pay for the clothes. Considering how many lives he just saved from being killed by the monster, it was just a good trade if he got an outfit out of it. Naruto started to walk out of the store, before he saw a speck of orange. He backed up, and looked to see a watch with an orange strap. He smiled to himself and took the watch for himself, attaching it to his wrist.

He found orange.

"Eel! Eel my friend, say it isn't so!"

Another demon.

"Eeeeeew." Naruto looked and saw a monster make completely of teeth, and not just white teeth, but yellowed, blackened, broken, and decayed teeth. The tooth creature turned when Naruto made his disguted sound, and went into attack mode instantly. It raised both of it's arms, before it swung them down.

It sent a barrage of hundreds of fangs at him, a wide range and high speed attack.

"You killed my friend... huh?" The tooth monster was confused when the human vanished, and all of the teeth he launched at him hit the glass behind him, shattered it, and peppered the walls like a shotgun blast. It looked around, and saw Naruto next to him, but before it could get another attack ready, Naruto knocked it upside the head with the back of his fist. He blasted the creature's skull into fragments with his backhand.

It's toothy body shattered and fell to the ground in pieces, with fleshy bits underneath the teeth. It was made of teeth and tooth roots. Naruto shoot his hand and got some stray teeth off of his new clothes.

"I feel dirty... I feel actually dirty just being around these two." Naruto started to walk away. There was a TV in one of the store windows.

"Currently, at the Shibuya mall, there are two confirmed Devils, the Eel Devil and Tooth Devil, please do not approach the mall. As of right now, 7 out of 20 deaths in Japan are caused by devils. If you're on your way to-"

Naruto tuned out.

"These things cause 7 out of 20 deaths... things as weak as this are a leading cause of death in this world?" Naruto couldn't see it. These things moved and attacked so dreadfully slow that he couldn't even imagine himself as a fresh Genin having much trouble with them. Even the loser samurai from his first C-rank mission hired by Gato could have taken down enemies of this level, and he took down those wannabe samurai with one blow each.

Naruto saw a few men and women in fancy black suits going into the mall just as he was leaving it. If they were going into the mall, and had weapons on them, then Naruto was sure they might be the protectors of the people.

'Well, I guess I should hold back as much of my strength when I deal with the normal people.' Naruto raised an eyebrow when he saw red hair. It was a beautiful woman, but she had an aura that felt off. "... well that woman triggers my sixth sense." Naruto deadpanned under his breath.

The woman stopped.

"Sixth Sense..." The red haired woman heard that, and she turned her head to look at the back of the blond's head that she just passed. She took a deep smell of the air, and she got his scent. She raised an eyebrow when she smelled a strange scent coming off of him that was unlike anything she had smelled before. "Nobody but me should... he wasn't a devil, his scent wasn't that... Well, isn't that interesting. Sir, can I have a-" The red haired woman had taken her eyes off of the blond for a mere second.

He was gone.

His scent didn't vanish, instead his scent trailed off far away to the top of a nearby building. He had crossed a 400 meter distance in less than the time it took for her to glance away. That was an immensely impressive speed, but the most important part was that he mentioned having a 6th Sense.

That shouldn't exist.

The very concept of a 6th Sense was erased.

'So... how does he have a 6th sense, when nobody should have one. Very interesting, I should put effort into finding that man.' The red haired woman smiled a very clever smile. She looked to where she smelled his scent had gone, and though he was out of sight, she wouldn't forget his scent. 'The Chainsaw ate the Sixth Sense Devil, meaning that other than myself and select few other devils, the very concept of having a sixth sense was erased... for me to trigger his 6th sense, would mean that he wasn't affected by the Chainsaw eating that concept.'

"Makima-san, the Tooth Devil and Eel Devils are confirmed to be deceased. One were defeated by a head to the head."

"Very interesting... the Eel devil is a rather strong devil for a human to handle." Makima, the red head in question, stated. She knew the blond from before would have been the one who defeated those two devils. She followed the scent in the mall, until she got to a clothes store, and found discarded clothes on the ground that had the same scent as the man from before. She picked up a torn shirt, and brought it to her nose.

"Makima-san?"

"This shop doesn't sell these clothes, and they aren't covered in fresh blood. So the person who killed these devils was wearing these clothes." Makima took a deep breath through her nose. She analyzed the scent that she got.

Male.
Teenager.
Human?
Powerful, extremely powerful.

She was able to identify the scent of strength, and a very male musk. She would guess by the scent that he was a teenage boy between the ages of 14 and 18, hard to say an exact age by scent alone. Since she passed by him earlier though, she would guess by his height compared to herself that he was between 164 and 168 cm tall. He was as tall as her, or slightly shorter. She wasn't as good with the visual details, since she hadn't gotten a good look at his face, just the back of his head.

Strange though.

She couldn't get a good gauge of his strength by his scent alone, as if there was far more strength that a mere scent couldn't display. He clearly had knowledge that he shouldn't have though, she clearly heard him mention an erased concept. That implied that he was somebody who had knowledge of erased concepts, but the concept of an erased concept didn't apply to him.

'His scent isn't like a human scent, but it isn't a devil scent at all. It's entirely unique to him. I smell something that doesn't exist.' Makima could smell something that just wasn't there. It was almost spiritual in what she was smelling. It existed, but at the same time it existed in an almost energy way. It was like she was smelling a conceptual scent, but a concept for something that did not exist, and thus could not be identified by scent.

Something was dangerously off about this scent.

If you smelled a flower, you knew you were smelling a flower.
If somebody burped in your face, no matter what that burp smelled like, you could identify it as a burp.

This scent had a smell, but not a scent that could be explained or identified as related to something. It was like trying to explain what sunshine smelled like, after leaving your futon out on the window to dry. You could smell the sunshine, even though sunshine itself didn't have a scent. It was a conceptual scent that couldn't be explained.

"Interesting, that is very interesting." Makima folded the shirt, the pants, and even the underwear that were on the floor. She picked up the weird sandles off the ground. She would take the clothes to her apartment later. It would be good for her to try and pinpoint all of the details of this scent, that way she could track it down.

She had a lot of planning to do with this interesting element.

Chapter End!
Please Leave Me Lots of Nice Long Reviews, But No Flames Please!

Remember: Naruto isn't from the Chainsaw Man universe, so anything that the Chainsawman has erased doesn't apply to Naruto. The concept of hair can be erased, and Naruto would still have his hair, because his body doesn't play by Chainsawman rules.
