While I am working on the chapter for FIREBRAND, I decided to write a little bit of a crossover between Naruto Namikaze (Universe-333) and Naruto Uzumaki (Universe-458). This also spoils some things for the future, mainly what happens in this scene. Just remember, this is several arcs away, and it can be considered both canon and non-canon.
Also, Happy Birthday Ayane!
Comparison
Naruto Namikaze (Firebrand): Flame Manipulation (Master), Regeneration that's stronger if he's exposed to the Sun, Pain Tolerance, Inferno Install, Advanced Intelligence, Magic Manipulation (Fire Elements Only), Portal Magic, Weapons Master, Flame Immunity, Rook Empowerment, Energy Burning, Horrible Cooking
Weakness: He has yet to reach 100% of Infernus' power (Can only bring out 20%). Separating the omnipotent demon from him will weaken him.
Naruto Uzumaki: Same abilities as canon, Power of Nothingness (Yet to fully master)(Mastery of it will turn his hair blue and make his eyes shine a brighter color), Ki Manipulation, Magic Manipulation (Limited to an extent), Advanced Intelligence, Culinary Intuition
Weakness: Over-exceeding his power's limits will render him unable to use them for random amounts of time, due to still being young. However, they become stronger than before once he regains his abilities, similar to a Saiyan's Zenkai boost. This will eventually stop once he's fully mastered the Power of Nothingness, or when his body finally adjusts to the power.
Plot
Universes Collide!
After failing to stop Shalba from using a powerful relic from the Hidden Gap, Naruto Namikaze wakes up the next morning and finds himself in an alternate universe, inhabiting a body that's his, but a year older. What's more, his parents are alive, he doesn't go to school, Moka's hair is pink, and Xenovia is not his girlfriend. In the FIREBRANDverse, Naruto Uzumaki finds himself a year younger and attending Kuoh Academy. As the two Narutos learn more about the others' world, they try to figure out what happened that caused the switch, unaware that the barriers keeping the two universes separate are breaking, the Hidden Gap opening on both worlds.
Universe-458
Morning
Naruto's House
Sainan Town
Waking up, a half-sleepy Naruto stretched his arms as he lets out a huge yawn. After rubbing his eyes, he observed his surroundings, noticing right away that it wasn't his. Or was it. Did Seekvaira remodel the whole house without his permission? Checking his closet, he notes how he doesn't remember buying the clothes he was looking at., nor did he remember throwing some away.
"Exiting the room, he noticed a young, teenage girl he was unfamiliar with come out of her room and say good morning to him. She had short, straight, brown hair, brown eyes, and wore a hairband decorated with two four-leaf clovers.
"Do I know you?" he asked her.
"Do you know me? I'm Hinami (Tokyo Ghoul), Big Brother Naruto," she told him, a smile on her face as she points to herself. "I've been living with you for over a year now. Did you get up on the wrong side of your bed?"
"Big...Brother?"
"You must've been hit really hard last night while you were out with Kirigiri and Issei." Naruto's eyes widened when she mentioned both their names. Issei had never met Kirigiri, and he didn't recall working with her last night.
"Perhaps you should stay home for today."
"I'm fine...Hinami. I'm just a bit off my game. Where's Xenovia, Kotomi, and the others? Did they head out for school already?" Hinami tells him they should be on their way to school before asking him why he wanted to know. "It's just strange how they left without me."
"Without you? You don't go to Kuoh Academy."
"...Come again?"
"Naruto! Hinami! Breakfast is almost done!" Naruto's eyes widened when he heard someone's voice call for them.
"Coming!" yelled a happy Hinami, rushing down the stairs to go to the kitchen. "Hurry up and get ready okay?" Heading down as fast as he could, he entered the kitchen and saw someone he thought he'd never see again. He could never forget that face. It was the first face he saw when he was born.
"Mo-...Mom..." Turning to face Naruto, Kushina says good morning to him before asking him why he hasn't changed yet. The blond couldn't bring himself to say anything as he stared at her. It was like seeing a ghost, except that ghost was flesh and blood.
"Naruto?" Kushina and Hinami looked surprised when Naruto started to tear up. "Naruto? Are you okay?"
"You're...You're here..."
"Of course I'm here," said Kushina, a smile on her face. "Don't you remember me coming over with Hinami to visit last night? A shame your father couldn't come. You know how he is when he's off working with Kakashi. I'm sure he'll be here for dinner before we-"
"Dad...Dad is alive too?" Naruto tearfully asked her.
"Did you have a bad dream last night and came down here worried about your dear ole Mom, Naruto?" Without saying anything, the blond rushed over to his mother and hugged her, surprising her and making her happy at the same time as Hinami watched them.
"I did, but now..."
"If you missed me this much, perhaps I should come here twice a week instead of just one."
Breakfast
Now dressed, Naruto couldn't keep his eyes off his mother as he ate her cooking. Savoring the taste, he never thought he'd ever get to taste it again. How he missed her cooking. At the same time, he started wondering what was going on. The house was smaller, there was a girl named Hinami who was his adoptive sister, his parents were alive, and he didn't need to go to school. Taking notice, Kushina asked him if there was something on her face.
"No, I just...I mean..." Naruto responds.
"You're not overworking yourself again, are you?" Kushina asked.
"I'm not. You don't have to worry about me, Mom."
"True, but when it comes to dangers bigger than what you can usually handle, I can't help but worry about you." Naruto tells his mother if she wants, he could take some time off. This was a nice time to catch up with his mother and find out what was going on with his surroundings.
"Big Brother Naruto, is Ayane going to be here for dinner?" asked Hinami.
"Ayane?"
"Your girlfriend," Kushina adds. "The one you've been dating for a few months now." Though he didn't know who Ayane was, he figured he'd play along.
"I'm so glad you found someone in Ayane, especially someone who's so much like me! Though...maybe too much like me. I do like Moka too...Perhaps..."
"Perhaps?" Naruto was about to ask something before his phone rang. Taking it out, Naruto finds the video call coming from Moka, picking it up and answering. Naruto was speechless when he saw her. This wasn't Moka. Moka had silver and pink hair, and eyes. This one had pink hair and green eyes.
"Moka?"
"Hey Naruto, is it okay if we hang out today? Things have been a bit hectic over at Yokai Academy, so I plan to ditch class with my friends to go hang out with Rias and her peerage today. Figured I ask you if you have time to hang out as well."
"Sure...I don't mind. Is Xenovia going to be there?"
"Yeah, I asked her already. Shirou is also going to be coming." Taking a sip of juice from his glass, Naruto spits it out abruptly when she calls Shirou Xenovia's boyfriend.
"Boyfriend!?" Something was definitely wrong with this picture. He was Xenovia's boyfriend, not this Shirou person. What happened while he was asleep?
Universe-333
Namikaze Residence
Waking up, Naruto noticed right away that something was wrong as soon as he found a naked and happily sleeping Xenovia in his bed. As Xenovia opened her eyes, the bluenette, in a tired manner, says good morning to him.
"Good morning to you as well, Xenovia." Getting up, Xenovia kissed him before telling him they should get ready for school.
"Of course, I'll meet you for breakfast," he told her, Xenovia nodding before leaving to use the bathroom. "There's no doubt about it. I'm in an alternate universe. There's no other explanation than that," he told himself, sounding serious.
"What's with the serious face Naruto?" asked a yawning Infernus, the blond not responding to it. "Naruto?"
"This body of mine, it's part Devil, and the demon inside me is not Kurama. In fact, he may be equal to or stronger than him..." Naruto thought as he got up to use the bathroom.
"What's up his ass?" Infernus wondered. Figuring he'd read his host's mind to find out, to his shock, he found out that his memories were different from the memories he's seen. Naruto's parents were alive, he was a ninja, the world knew who he was, and he had a sexy purple-haired kunoichi as a girlfriend. Before Naruto could enter the bathroom, he found himself unable to move.
"Who the fucking hell are you?" Infernus asked in a rude and confrontational manner.
"Naruto Uzumaki, you must be the demon inside me."
"Uzumaki?" Infernus lets go of Naruto before introducing himself to the blond.
"I take it our surnames are different in this universe."
"This universe?"
"It's best if I explain things to everyone this universe's Naruto knows."
Kitchen
Everyone's eyes were wide open as they focused on Naruto, who was cooking, without burning the whole place to the ground!
"Did we miss something?" asked Maki, unable to stop staring at how masterful the blond was with his cooking. Aware of all the eyes on him, Naruto wondered how horrible of a cook this universe's Naruto was.
Regarding Kushina and Minato, they're alive. They were dead, but in a future 458th Universe story involving Rosario Vampire and High School DxD, a certain fight with a villain with reality overwriting powers caused ripples that altered reality in the 458th Universe. However, they had some amnesia before coming to Naruto and having a heartful reunion with them. They then adopt Hinami Fueguchi, making Naruto and Hinami brother and sister, and so Naruto has his own space though they do visit from time to time.
For work, Kushina and Minato work closely with Kirigiri as members of the Future Foundation, and they do a lot of traveling, Naruto paying for their tickets. Naruto also bought them a house, and Kushina decides to rebuild the Hidden Whirlpool Village and make it the main headquarters for the Shinobi Alliance, putting Tsunade in charge of it.
Regarding Naruto of the 458th Universe, he has more experience with having a demon in his body than Firebrand. This also allows Naruto Uzumaki to use more of Infernus' power.
One last thing, Chelsea is alive in the 458th Universe, it's just that Kurama, before he turned good, used his power to make her disappear when she (Chelsea) was only a baby. He was a huge dick back then. Kushina will try to go look for her.
Akame is in the 458h Universe, though she hasn't met Naruto or anyone else yet. This crossover will have Naruto of the 458th Universe decide to go visit the Empire right after, beginning a crossover with Naruto and Akame ga KILL!
