Disclaimer: First Chapter
Spoilers Ahead: As I was writing this chapter, the newest chapter of Chainsaw Man absolutely fucked with what I had planned. Thankfully, I thought of a way to salvage the story with some minor edits on Chapter 27, and change the conversation during this chapter.
Story Start!

"So... I managed to find a suitable host to the War devil, a girl who recently lost her mother. She said she would be willing to share her body, as long as she could get revenge on the devil that caused her mother's death."

"... You are telling me this... why... I'm locked up by Control, Makima as you know her." Fami stated as she tilted her head in a way that reminded Naruto a LOT of a hanged person, a person who had a noose around their neck. She glanced towards Naruto as he sat across from her in the interrogation room that she was in. "Do you just want to get to know me?"

"Control, Death, Famine, and War. The 4 of you make up the Horsemen, right... well... Makima can't see people's faces well, and after capturing War, I've noticed that she is horrible at remembering faces as well. So..." Naruto leaned forward and gave Fami a chance to memorize his face. He memorized her face as well, including every mole on her face, all 5 of them. She had a very pretty face, but it was very pale. "... take your shirt off." Naruto stated to her.

"Huh?" Fami asked.

Naruto leaned forward even more.

"Take. Your. Shirt. Off." Naruto told her, so she stood up and she unbuttoned her blouse, before she started to follow his orders. She revealed the bra that she was wearing underneath her shirt, and she finished removing her shirt.

She had a normal, but very attractive, body.

Filled out nicely.

"Why did I take my shirt off?" Fami asked Naruto.

"Makima almost always has her hair in a neat and orderly braid, and she always keeps her uniform nice and clean. When we have sex, she always makes sure to change the sheets right after we do it, and her apartment is spotless. Makima is always in control of her body and surroundings that way." Naruto explained as he looked at Fami's chest.

Not her chest, but her ribs.

"Yes?" Fami asked as she spun around slowly to show Naruto her mostly naked torso.

"I only talked to War for about 2 minutes after capturing her, but she's kind of stupid and chaotic. When given the offer to get a human body, she wanted one that was maimed first. The girl agreed to let herself be killed, and when she was revived by War taking over 30% of her brain, the scars of her death showed up whenever War was in control." Naruto explained, since while Makima had been keeping track of Famine and explaining the situation to her, he had been capturing War and getting her to agree to an alliance.

So, he visited all of Reze's victims and tried to see if any of them would agree to allow a devil to become part of their bodies, and one of the victims agreed so long as she could take her revenge against Reze as payment.

"Yes, War was always the dumbest of us." Fami stated as her head tilted even more.

She had a long beautiful neck without a single flaw to it.

"Makima can't remember faces, only scents. Well, after smelling you, Makima, and War... I noted something. All of you have the exact same scent." Naruto stated as he pointed out something he had noted the second that War had gotten a Fiend body instead of a pure devil one. Naruto looked at Fami's plush thighs, and her wide hips. "Also... tell me what your name is again?" Naruto asked her.

His body lit up like it was on golden flames.

"It's Famine, you can call me Fami." Fami stated.

"... No malice or any ill intent when you said that, but there was a hint of fear. You felt fear when you told me your name." Naruto stated as he powered down, and he stood up. "It was just a little though." Naruto stated as he got ready for a fight for a moment.

She didn't fight.

"I can't defeat you, so I'm not going to try and fight you either. I saw what you were able to do to the Bomb girl, and that nightmare scares me too much. I would rather not become a statue for eternity." Fami didn't make any motions at all to fight Naruto, even though it was obvious that by instinct she had almost tried to do it. She had felt a strong self-preservation instinct kick in that told her to run or fight, but she was wise enough to not do so. "... and I can remember your face well enough. Blond hair, blue eyes, whisker marks on each cheek. Three of them to be precise." Fami explained to Naruto.

"You've never died." Naruto stated to her.

"Huh?" Fami asked.

"You've never died. Most devils don't seem to bother remembering human faces, and devils like Makima struggle to even remember devil faces. When a devil dies, they lose all their memories and reincarnate... They have no reason to try and remember a person's face, because once they die, they become a new person." Naruto pointed out to Fami.

"... All I did was remember your face." Fami pointed out to him.

It wasn't that impressive.

He had a very distinctive face.

Naruto took a piece of paper out of his pocket, and he passed it to Fami. She took it, unfolded it, and saw a very crude drawing of Naruto.

It was wrong though.

It had 4 whisker marks on each cheek, the hair was a mix between very light brown, almost blond, and at some parts it was just red. The eyes were way off though, one of the eyes was purple, and the other was blue, but it was the wrong shade of blue.

"Makima drew that when I asked, and even though she has TRIED to remember what my face looks like, she actually struggles to draw any of my features correctly from memory. I've had sex with her, I live with her, and she can barely remember my face right." Naruto pointed out with a smug smile.

"So?" Fami asked him.

"So you've never died! You've never experience death, and thus, you've never had to experience was it is like to reincarnate and forget your past life. You can remember people's faces very easily!" Naruto looked smug, as if he had solved some great riddle.

"Okay, so I've never died... your point?" Fami didn't understand why he wanted to talk to her about this.

"Only the Primal Fears have never experienced death. Even Makima isn't the first Control devil, she's only the current reincarnation of the Control devil. So, you can't be War or Famine... which makes you the Death Devil, not the Famine Devil!" Naruto pointed at her.

She raised an eyebrow.

"What makes you think that. Famine might not be a primal fear, but maybe I've only ever died once, while Makima has died many times." Fami pointed out.

Naruto grinned.

"Because, you aren't skinny like a person who has a body of famine should be. Your hips are wide and have some fat on them, your legs are thick, and I can barely even see your ribs. You eat a lot, you eat a TON... but if you were the Famine devil... wouldn't that mean you eat as little as possible, and savor every meal... instead, I've seen you shovel food in your mouth like an animal. You act like a hungry person, but you don't act like the incarnation of Famine, and your body doesn't look the part. You're way too well developed... your butt is too big to be the Famine devil." Naruto stated, crossed arms and looking extremely proud of himself.

"... Have you told Makima?"

"Why would I do that, if she hasn't figured out who you are, why the hell would I tell her? She thinks your Famine, and I think it's hilarious to watch her make schemes around it. She's been trying to manipulate assassins to attack me and distract me long enough for Denji's heart to be-"

"Denji who?" Fami asked.

"Chainsaw hybrid, his heart is the devil part that lets him transform. Makima wants to get her hands on his heart, revive the Chainsaw Devil completely... though she can't use it to erase her sisters like she planned. She is a greedy, selfish woman... and I've made it my mission to make her plans fail whenever I see her plotting." Naruto stated with a wide and playful smile.

Fami looked very confused.

"Why though... if you can turn Makima into a stone toad-"

"I can't, she has a contract that transfers stuff to random people in Japan. There is a small chance that if I turn Makima to stone, then thousands of random people will start turning to stone instead of her. Makima and I have a bit of a stalemate... I'm too strong for her to do anything, and she's too tricky for me to risk putting her down." Naruto explained the frustrating part, because yeah, he did have possible tricks to taking down Makima for good if he needed to, but the death count for innocent people would just be way too high to risk it.

"I would take that chance."

"I'm not a devil, I'm a human, and I could not live with myself if my actions caused countless of innocent people to die." Naruto snapped at her for the statement, and she wisely shut her mouth. "Which is why..." Naruto stated as he walked towards Fami.

She stepped back.

Naruto grabbed her chin and brought their faces closer together.

"I'm going to gather War, Famine, Death, and Control all together, and I'll be your prison for all eternity. My arms will be your prison bars, my blood will bind you all." Naruto stated with his grin growing even wider.

Fami was confused.

"How will you do that?" Fami asked.

Naruto transformed as his hair turned red, his eyes turned gold, and a halo of guts appeared over his head.

"I'm the Control Hybrid, and I can take control of people who I see as lesser than me... and you're a person who lied about who she was to her sister's face. I know I'm stronger than you, because you admitted it to me... and now... make a contract with me." Naruto demanded as he formed a knife hand and stabbed himself in the chest with it.

"What contract?"

"Simple... I get one of your lungs, and in exchange, you can't leave Japan. You're stuck here, with me, where I can always keep my eye on you." Naruto stated as he shoved his lung into Fami's body, and while his hand was still in her chest, he ripped out one of her lungs and shoved it inside of his own body. He replaced the missing lung with her lung.

"It's a deal." Fami stated.

Before she broke the control that Naruto had over her, the second he made a contract with her, he saw her as an equal and thus could no longer control her. Still, once the contract was made, the lung inside of her body became a part of her. Her lung inside of his body became a part of him as well, and his wound healed up due to his own healing ability, while hers did the same thing.

"You... forced me to make a contract with you." Fami stated with her eyes narrowing slightly.

"Yep, and now you can't escape. No matter where you go in Japan, I can keep my eye on you. You may have Makima fooled, and you may be able to fool War-"

"... What about the actual Famine devil... and if War is a Fiend, what will you take from her?" Fami interrupted Naruto.

He paused.

"Oh... right... you're not actually Fami... I'm going to keep calling you Fami anyway until I find the real Famine Devil, and I'll keep your real identity a secret from Makima, as for War... well she's already bound to a human girl now, and I made sure she only took 30% of the girl's mind. So all in all, I think 3 of the 4 Horsemen have been neutralized." Naruto clapped his hands at a job well done.

"Makima is still plotting and scheming though... what will you do to take her out?"

"Nah, I don't need to. Makima is becoming more obsessed with dominating me in sex, meaning that I can control her by refusing to have sex with her eventually. Her desire to dominate me, will give me the ability to keep her on a short leash."

"You're weaponizing... submission... to become dominant..." Fami was very confused.

Naruto snapped and points at her.

"Yep. I'm weaponizing my stupidity, and the fact I'm a bottom during sex with her, to dominate her and keep her controlled. The way I see it, the more Makima enjoys taking control during sex, the more and more I can take control outside of sex... I just have to allow Makima to think it was her idea." Naruto grinned.

"You're a devil."

"I'm a human, and we're some tricky sons of bitches." Naruto grinned in total confidence.

Still, after this he needed to go and talk to the War Fiend and her human host, just to make sure that he was able to find some way to control them as well, to keep them on a tight leash like he now had on Death and Control.

A ninja's work was never done.

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

Originally, in this chapter Naruto was going to confront "Famine" and force her to reveal what the Death Devil looked like so he could track her down, but considering the reveal in the newest chapter of Chainsaw Man, had to change this last minute.
Still, I was able to find a goofy way that Naruto may have figured out Famine wasn't Famine, that she might be Death.
