Note (6/27/2021): Just putting this out here, in the case people wrongly assume this is an OC, it's not. This isn't someone made from scratch that shares the same name as the titular character in the anime NARUTO. This is Naruto Namikaze, a version of Naruto in another universe, designated as Universe-333. I already mentioned a multiverse so remember that almost every universe has a Naruto, each with a different origin and abilities.

I do not like how people think this is an OC. He isn't. He's out of character, but everything else, mainly his appearance is the same. I do not get why some think Naruto Namikaze is an OC. He's Naruto with his father's last name.

Once again, this note is to let the readers, old and new, know that Naruto Namikaze is, once again, Naruto but with Minato's last name instead of Kushina's. If a character in here was an OC, I'd let them know at the end of a chapter or when introducing one.

Full Name: Naruto Uzumaki Namikaze

Aliases: Firebrand, That Really Hot Guy, Bearer of the First Flame, The Conqueror of Women

Race: Reincarnated Super Devil

Family: Minato Namikaze (Father(Deceased)), Kushina Uzumaki (Mother(Deceased)), Chelsea Namikaze (Older Sister), Akame Namikaze (Adoptive Sister), Jiraiya(Godfather)(Guardian), Karin Uzumaki(Cousin), Maki Nishikino(Cousin), Mahiru Koizumi(Cousin)

Bio: Having been stabbed protecting his cousin Maki from a crazed fan, 16-year old Naruto Namikaze begged whoever could hear him to let him live. As luck would have it, someone did hear him and saved his life. That savior was Seekvaira Agares. However, another "savior" came to his rescue in the form of the spirit of Infernus, an omnipotent flame demon who went up against Trihexa and died for it, though not before inflicting the first wound to the Apocalyptic Beast. In return for allowing the demon to inhabit him in order to help him exact vengeance on Trihexa, he must listen to him and help serve his King and protect the important people in his life.

Appearance(s):

Kuoh Academy: When attending Kuoh Academy, he wears their standard uniform. He wears a pair of [fake] glasses to make himself look uninteresting, but at some point, he decides to stop wearing them.

Firebrand Outfit 1 (Chapter 5 ENHANCED): Naruto wears a black solid cotton casual slim fit hoodie jacket with long sleeves and is double zippered. Naruto adds in a magic-enhanced titanium pauldron on the jacket's left shoulder that connects to a titanium gauntlet as an aesthetic. Underneath the jacket is an orange t-shirt. He wears a pair of black jeans to go with the jacket that comes with carbon fiber knee pads. Naruto later makes a belt to holster his sawn-off shotgun and eskrima sticks. Naruto wears a pair of slim-armored boots with iron soles.

Firebrand Outfit 2 (CHAPTER 15)(Current): With help from Shirabi, Naruto gained a new outfit. It's similar to the Pyonkichi Mk-V Armor in Danmachi, minus the arm guards. Like the previous outfit, it comes with a hood and a mask that covers the lower half of his face. He also wears a pair of armored hi-tech gauntlets that help concentrate his attacks. He keeps the carbon fiber knee pads from his first outfit along with the slim-armored boots with iron soles.

Firebrand Outfit 3: TBD

Love Interests(For now): Moka Akashiya (Childhood Friend), Xenovia Quarta, Seekvaira Agares, Sayaka Kirasaka, Red Saber, Shino Asada/Sinon

Skills: Naruto has high computer and engineering skills, being able to build his own devices out of spare parts when he was 10 and creating a 3D Printer for his own inventive needs when he was 13. Naruto is also an expert in chemistry, being able to fight Exorcists, Stray Devils, and Fallen Angels by utilizing dangerous chemistry-made explosives, poison, and gadgets. Naruto possesses near-photographic memory, being able to read through advanced spell books and remember how to use them. Before he became a devil, Naruto lacked combat skills and he wasn't very muscular. After becoming a devil and Infernus's host, Naruto went through rigorous training, becoming a skilled martial artist with a fighting style that mixed his quick and powerful strikes with parkour. Aside from combat and smarts, Naruto is, surprisingly enough, an amazing singer and piano player, having taken lessons from his cousin when he was in elementary school.

Abilities:

Transformation: When Naruto uses his powers, his spiky blond hair is enveloped in flickering flames. Depending on what flames he's using, it can either be orange, yellow, red, or black, depending on the user. There may be more colored flames that he has yet to discover/reveal. His eyes also turn red and slitted and his canine teeth grow longer and sharper. If angry enough, Naruto's eyes give out an intense glow.

Super Strength: Thanks to becoming a devil and Infernus's host, Naruto's strength is enough to overpower Issei and Vali with little effort. It's unclear how strong he is, though it's been known that the more intense his flames are, the stronger he gets. He also gains extra power if exposed to sunlight.

High Endurance: While Naruto can be hurt by holy weapons, he has a very high pain tolerance, being able to fight despite being pierced by several holy spears.

Regenerative Healing Factor: Naruto's powers allow him to heal wounds faster than Twilight Healing and Phoenix Tears. If exposed to sunlight, he's nearly unable to be hurt.

Fire Manipulation: Naruto's main ability is to control and generate fire for his own use. This also makes him resistant to fire and seemingly no flames are capable of burning either him or his clothing. He is able to imbue an object he touches with fire, using the object as a melee or ranged weapon. While Naruto's body only has a 20% access to Infernus's powers, it's still very formidable.

Super Speed: Naruto is fast enough to fight against most high-speed enemies and tire out ones who rely solely on their strength.

Short Teleportation: Naruto can teleport short distances, bursting into flames as he does it.

Flight: Since he's a devil, Naruto can sprout wings, though he prefers running instead of flying, only flying when he deems it necessary.

Stealth: Naruto has trained himself to infiltrate and gather information without being detected.

Sling Magic: By tracing his right hand in a circular pattern while focusing on a destination beyond the space directly in front of him, Naruto can create fiery portals. He can create up to two portals for a variety of uses.

Inferno Install: Naruto can access a portion of Infernus' full power for a short period of time. When he accesses the form, his body will have a luminescent appearance with a black silhouette. He also acquires sharper claws and nine flaming foxtails. The Inferno Install Naruto has access to is incomplete, since Naruto doesn't have full control over the demon's overwhelming power and his body can't handle its full power. Given time, Naruto will slowly adjust to its power and eventually master it. Its final form is a mystery.

Equipment:

Igneox: A multi-purpose weapon that Naruto designed himself. It functions mainly as a quarterstaff. It can split into a pair of eskrima sticks and single-edged short swords(if Naruto infuses his fire powers into the weapon(s)). When using Inferno Install, Naruto can transform it into a single-edged greatsword that can be used with one or two hands. Naruto constantly upgrades it over time.

Sawn-Off Shotgun (Upgraded): Naruto picked this up after fighting his first devil, using it to finish it off. Taking a liking to it, Naruto kept it. After its destruction, Xenovia took some of its pieces and had the forger make a new one, adding upgrades to it and making it stronger than the original.
