Demon Slayer is a smash-hit shonen action series that makes good use of the "monster hunter" formula like D.Gray-Man, Fire Force and Bleach, among other titles. In Taisho-era Japan, flesh-eating demons stalk the night, and only sword-slinging demon slayers stand a chance against them in mortal combat. This is not an easy job, even for the elite Hashira.
Kaguya Ubuyashiki, the head of the demon slayer corps, is ready to expand his recruitment efforts and train new demon slayers from other anime series, and that includes hit fantasy titles like Fairy Tail. True, not many of Fairy Tail's characters are trained with the sword, but they still have what it takes to make it as a slayer and defeat the Upper Moons.
10 Erza Scarlet Is The Mighty Swordswoman
A few of Fairy Tail's best characters are already used to wielding weapons in battle, and that includes the notorious Erza Scarlet, an S-ranked wizard in the Fairy Tail guild. Erza's magic allows her to reach across the dimensions to access her many suits of weapons and armor, making her highly versatile in battle.
With or without that magic, Erza has the strength, durability, and technique needed to fight the Twelve Demon Moons, and she's got an indomitable warrior's spirit to match. Erza could easily make it as a Hashira and take the fight to Muzan's hordes as a newly minted demon slayer.
9 Kagura Mikazuchi Is Erza's Best Rival
The most powerful wizard of the all-female Mermaid Heel guild is Kagura Mikazuchi, and in most regards, she is Erza's true equal and rival. As she proved in the Grand Magic Games tournament, Kagura can match Erza blow for blow with the sword, and she has unique magic to offer.
Kagura can use her gravity magic to crush any foe put before her, and that, combined with her swordplay, means she could rival any Hashira if she ended up in the Demon Slayer world. Kaguya Ubuyashiki urgently needs her to take on the Twelve Demon Moons as a uniformed demon slayer.
8 Gajeel Redfox Fears No Enemy

The iron dragon slayer Gajeel Redfox is a redeemed villain who once belonged to the Phantom Lord guild along with the water wizard Juvia Lockser. Now they both fight for Fairy Tail, and they're not afraid to take on the strongest dark wizards or monsters out there. Or demons, for that matter.
Gajeel is a brute-force fighter who can conjure large iron rods to demolish his foes, but now it's time to trade his iron magic for nichirin blades. It'll take some getting used to, but Gajeel could learn to fight demons with a sword, and his iron skin will protect him from even Akaza's fists.
7 Lisanna Strauss Is Quick & Agile
It's true that Lisanna Strauss ranks among the weaker Fairy Tail wizards, but that guild's standards are quite high, which works in Lisanna's favor. She is also comfortable fighting powerful foes in close-range combat, which is essential for any demon slayer.
Lisanna could combine her cat form's agility with her newfound swordsmanship to become an agile, fleet-footed demon slayer who emphasizes mobility and trickery over brute force, and that should serve her well against a wide variety of ordinary demons. She might remind Tanjiro of his sister Nezuko, in fact.
6 Bisca Connell Could Snipe Demons With Ease
Most demon slayers are expected to fight Muzan's minions up close with the sword, including all nine of the Hashira. But it's still possible to use anti-demon materials to build ranged weapons, even shotguns. That's what the sniper wizard Bisca Connell needed to hear.
Any demon slayer who needs fire support can rely on Bisca Connell, who could threaten even the Twelve Demon Moons with specialized bullets forged from sun-soaked ores. Other slayers can lure the demon into the open, then Bisca can put a few rounds through their heads to incapacitate them. She will need some bodyguards during such a battle, though.
5 Bacchus Groh Could Use Nichirin Knives In Battle
If Kaguya Ubuyashiki hires new demon slayers from other anime, he and his subordinates will have to get creative with the weapons those new recruits will use. Not everyone shines when using a sword, so new demon slayers like Bacchus Groh can use knives instead.
Bacchus is a martial arts master who works best with his bare hands, but he'll need nichirin material to slay demons. So, he can use two knives and incorporate them into his fighting style, which would make him a threat even to the Upper Moons. He could become the demon slayer corps' own Akaza.
4 Laxus Dreyar Can Endure Any Demonic Attack
The lightning dragon slayer, Laxus Dreyar, is another S-rank wizard in the Fairy Tail guild who can defeat almost any foe in single combat. He can even narrowly defeat Erza if he really pushes himself, meaning he should do fine against most of the Twelve Demon Moons as well.
Laxus rarely uses weapons, but he wouldn't mind training with a sword to take on demons and show them what an S-rank wizard can do. Like Erza, Laxus has enormous strength and durability as a close-range fighter, which is his way of matching a typical demon's regenerative abilities.
3 Mirajane Strauss Is A Battle Demon
Another melee powerhouse in the Fairy Tail guild is Mirajane Strauss, the oldest and strongest of the three Strausses. While her little sister Lisanna relies on agility and animal traits to fight, Mirajane uses downright demonic powers to demolish her foes, and in Fairy Tail's setting, Mirajane is fighting fire with fire.
Mirajane would gladly train with nichirin swords if it means protecting innocent people from the wrath of demons, and she would soon be seen as Hashira level and then some. If Mirajane had been there when Kyojuro Rengoku fought Akaza, things might have turned out differently.
2 Ultear Milkovich Can Handle Any Foe Up Close
The redeemed villain Ultear Milkovich is at her strongest when she uses specialized magic, such as time-based spells or ice-make magic like Gray's, but she's not helpless in close-quarters combat. Ultear has formidable physical strength and excellent martial arts skills, and she can even use a sword.
Ultear is determined to prove her worth by fighting the forces of evil to defend the innocent, and Kaguya Ubuyashiki will give her that chance. He would gladly hire her as a new demon slayer and ask her to defend the people from the wrath of the Twelve Demon Moons. Now, this is a worthy challenge.
1 Minerva Orland Rivals Erza's Strength
Minerva Orland is yet another wizard who works best at close range, meaning she would be perfectly comfortable switching careers to being a demon slayer instead of fighting for the Sabertooth guild. Minerva is a master martial artist, like Ultear and Bacchus, and she can even stand up to Erza and Kagura.
Minerva would confidently take on any Twelve Demon Moon with her bare sword alone, and her reckless bravery would inspire all the other demon slayers fighting by her side, too. Minerva will show Tanjiro's squad the fearsome fighting spirit of Sabertooth.
