Demon Slayer.

As a youkai herself, Koneko couldn't imagine those existing to be fair. This was her honest to goodness, first time hearing about them. She was a youkai born and raised in the underworld, she didn't know a lot about Japan other than some small cultural things she learned while attending school. So hearing that her species had a natural enemy, Naruto did admit to being a Demon Slayer and she was a monster, was a little shocking. It explained why Naruto's smell put her a little on guard, but she had always just assumed it was because they were always fighting each other.

"Fuck... one day into learning this stuff, and I get attacked... just my luck... come on powers, why are you so fucking useless?" Naruto asked as he looked down at his hands. The wind he had brought out had barely been enough to do more than blow her hair. "Shrimp, you get out of here, I'm going to distract her." Naruto stated as he gripped his hands into fists. He brought Koneko here for selfish reasons, and he wasn't going to get her killed because of somebody after his life. At the moment, the two of them were hiding inside of the snack bar, while Shizuku looked around for them.

Koneko was tempted to take that offer.

'He's going to die if I leave.'

"... Now run." Naruto stood up and grabbed the closest thing to a weapon he could grab without looking, and started to make a run towards Shizuku as her back was turned. Not a very brave thing to do, but a sneak attack was his best bet. Naruto glanced behind him, and saw Koneko running for it faster than he had seen her moving before now. Grinning, he jumped over Shizuku as she turned to look at him. "Other side, now take this!" Naruto shouted as he raised high his weapon, and brought it down on top of her head.

His mighty plastic spoon, collided with the top of her skull, with enough force... to break the plastic spoon.

Shizuku just took a moment to turn around and fully face Naruto, looking at the snapped spoon that was in his hand and on the ground. Naruto was looking at the weapon that he had grabbed, before he looked at her.

"For a Demon Slayer, you're-"

"Pocket salt!" Naruto reached into his pocket and pulled out a pocketful of salt he had nicked from the snack bar, and threw it into Shizuku's face. She got a complete face full of the salt, and started to hiss as she rubbed her eyes viciously. Naruto grinned and pulled his fist back, seeing his chance to launch a way better attack, and this time when he punched her across the cheek, his hand went right through her body. "Eh?" Naruto paused mid-punch to see his fist going through a completely transparent Shizuku, her body now completely made of water that splashed against the ground and wrapped around his ankle.

The water picked him up, and threw him a good 20 feet away, back into the snack bar, busting the door of the fridge wide open.

Shizuku looked visibly annoyed with him.

"That was a dirty trick... I'm going to kill you, have the decency to face me like a man ya know." Shizuku could hardly believe that this boy was a Demon Slayer by the complete lack of dignity towards battle he possessed. Demon Slayers 100... even 200 years ago would have attacked her face first. They wouldn't have launched any of that surprise attack foolishness he just did. They were far too prideful, because a sneak attack was something you only did against an enemy you understood had a chance to beat you. No Demon Slayer viewed an ayakashi as their equal, it was just the way of the world.

Naruto staggered to his feet.

"Fuck!" Naruto shouted as he grabbed something that was sticking out of his shoulder, and ripped it out. "Now I get the knife... FUCK... of course I did a sneak attack dumbass. I'm only bait so that the Shrimp could get away safely." Naruto jumped over the counter and rolled out of the way as a thin stream of water sliced the building he had been inside of. Naruto looked at it slide, before the roof of the building collapse and crush the inside of the small building.

So water could cut things... that was awesome, bad for him, but still awesome.

"Water is one of the most dangerous elements, and in this water park, you will breath your last ya know." Shizuku pointed a finger at him, and water floated behind her, turned into ice shards, and flew at his face. Naruto's hand reached up by instinct and caught the ice shard, before he rolled across the ground and dodged the others as they stabbed the concrete. Once they were stabbed into the ground, or in his hand, they stopped moving, and Shizuku made no effort to regain control of them either. "... I almost forgot your kind were good at martial arts... but as you've noticed, they don't work on me." Shizuku raised both hands up and formed a large sphere of water.

Naruto's face went blank.

He had a plastic knife in one hand, and an ice shard in the other... against an enemy that used water and could turn into water. Overall, his chances were not amazing, or good, and he couldn't control his powers very well, so maybe his chances were looking a little bleak. Still, Naruto got up and ran up the wrecked building, just as the water flooded the spot he had been. Tentacles of water moved towards him, and he jumped down from the top of the wreckage, back to the other side. Quickly ducking down so that Shizuku couldn't see him, the tentacles rushed towards where he would have been if he had chosen to run away.

'Okay, so she isn't all knowing... when she can't see me with her eyes, she can only guess where to attack with water... awesome... that doesn't change anything...' Naruto stuck the bloody knife into the water as it pulled up, and part of the water became visibly red. Shizuku lost control of the part of the water that his blood was in, and as it raised over the building, the tainted water splashed the ground. "She can't control bloody water either... now that is useful." Naruto grinned, since he had just planned on making the water bloody to make her think she stabbed him, then sneak away.

Now though, he could work with this.

"Did you really thing I would be that dumb ya know... I won't fall for anymore tricks." Shizuku hopped over the wreckage and in front of him. Just because she saw bloody water, did not mean she was going to let herself be tricked this time.

Naruto grinned.

"You fell for that first one pretty easily... guess you have to be pretty dumb." Naruto taunted her, and she put her foot right on his chest, forming a blade of water around her hand. Naruto drew a cut into his leg with the ice shard, that she seemed unable to control after her first attack with it. She said nothing as she swung her blade down at his neck, and he just raised the ice shard and blocked the water with the blood covered tip. Shizuku was a little surprised when she lost control of the water, and it splashed Naruto harmlessly, no longer a thin water blade. "Don't underestimate Naruto Uzumaki!" Naruto shouted as he punched Shizuku in the face.

The water that her body turned into splashed around him, before she reformed as he was standing up.

Right, she could do that too.

She swung her finger, and shot a thin stream of water at him. Naruto wiped his hands across his bleeding shoulder and leg, before he blocked the water with bloody hands. Both of his hands were cut open a little, enough that his blood splattered on Shizuku's face, but his idea worked well enough to save his neck from her attack. So, Shizuku knowing her attack did little to him, made to kick him in the ribs. She opened her blood covered eyes when she felt Naruto grab her leg, only moving back a little from the surprising amount of force behind her leg.

"Better, now I won't feel any guilt for killing you ya know." Shizuku still had full faith in her ability to kill him.

There was no chance that he could do anything against her.

"Then I don't feel any guilt over THIS!" Naruto slugged her in the face, full force, and she turned into water. The exact moment she returned to physical form though, Naruto's fist slammed into her face again, only this time she was knocked away by it. Getting blasted right off of her feet, quick reflexes let her catch herself and land on upright, but she still felt the impact of that attack rumble through her body. "... That worked... looks like you can only turn into water, when you see the attack coming after all. Right when you reform, you're not able to turn into water again for a split second. Holy crap, I am considering that a win! Finally, one of my plans worked, and my bad luck didn't mess me up!" Naruto raised his arms up.

She glared at him for not taking this as seriously as she thought he would have, and she wordlessly made an entire pool of water lift up into the water, and float above them. Naruto looked up, and she took a dark satisfaction when his smile faded away.

No dodging this one.

"Nobody will recognize your corpse ya know." Shizuku's words fell on deaf ears as the water dropped down on both of them, capturing Naruto in the water, before floating back up into the air. She was going to drown him to death, like she had originally planned... and then crush the corpse for good measure. "Time to... what?" Shizuku saw as a yo-yo was tossed into the water right into Naruto's open hand.

She turned her head, and saw Koneko was standing there, having thrown the yo-yo.

This youkai came back to save a Demon Slayer?

"Idiot, do something stupid!" Koneko shouted at him, and in the water Naruto sent her a thumbs up. Grinning, Naruto threw the yo-yo out of the water and allowed it to wrap around Koneko's hand. Koneko grabbed the wire, and yanked Naruto right out of the water, so that he landed on the ground next to her. Sliding, Naruto raised his arms up, and grinned down at her.

"You came back... didn't know you cared about me... lets knock her out cold and get out of here." Naruto watched as Koneko got ready for a fight as well.

Koneko didn't comment.

'... I shouldn't mention that there was a barrier keeping me from leaving... but all the same...' Koneko glanced at Naruto, and gave him a quick nod. 'I won't be satisfied with him sacrificing himself to save me.' Koneko didn't mention that either, she just got ready to fight against Shizuku.

Said girl just looked at them.

"... This is... strange... are you not disgusted to have her fight with you ya know?" Shizuku pointed at Koneko, and looked at Naruto for an answer.

"Of course not, this girl might be a shrimp who can't keep her damn mouth shut, a flat chested loli with a bad attitude, and... well, Koneko is one of the few people in this world who has my respect." Naruto could feel Koneko's glare on his skin, and he knew if he pushed it, then he might have two murderous lolis to fight. Koneko nodded her head, and she glanced at Naruto.

"... I'm going to kick your ass tomorrow."

"Oh, you sure about that?"

Shizuku just watched that exchange, before she made all the water go back into the pool. Koneko watched as the destroyed building started to fix itself, as the barrier that had been placed over the park fell away. Shizuku just turned into water and sank into the pool, leaving the fight without saying another word. With the park fixed up, she left a confused Naruto and Koneko to wonder what had just happened.

"... Knock her out? Shouldn't you have been trying to kill her?" Koneko pointed out as she dropped her fists. Making a barrier like the one this girl made took time, and dropping it was a pretty big indicator that the girl was going to stop fighting.

Naruto rubbed the back of his head.

"Well... I mean... I might be a Demon Slayer, but I don't really hate them... I just learned all of this yesterday. If I killed her, then her opinion of me would never change, and I would have more of her kind after me. Killing somebody should be saved for a last resort, not the first option. Doesn't everyone deserve a second chance ya know?" Naruto asked Koneko with a wide grin.

...

"Also, you and that girl both have the same verbal tic."

Naruto would be lying if he said that was not a factor.
