Any action-packed series would be incomplete without the addition of an elite force of warriors (or sometimes a mentor) to guide the main character through their physical growth. Demon Slayer is no exception to this rule. The Hashira are the strongest rank of the Demon Slayers Corps, and for good reason: one of the conditions to become a Hashira is killing a member of the Twelve Kizuki, an elite group of demons that serve Muzan Kibutsuji.
Each Hashira has a special fighting style that makes them unique, and they're stalwartly dedicated to bringing down Muzan. Lots of other series also contain unique and powerful characters dedicated to a worthy cause, including Final Fantasy. While they might not use any Breath techniques, there are plenty of Final Fantasy characters who could be powerful Hashira.
10 Zack Fair's Upbeat Attitude Will Serve Him Well As A Hashira (Final Fantasy VII)
Being a Hashira is a tough and often heart-breaking job. Hashira know that they're the best-equipped to protect humans from demons, but they can't be everywhere at once, meaning there will be plenty of people they will not able to protect. Zack's optimism will motivate his fellow Hashira and his dedication will carry him through the casualties. By Final Fantasy VII's standards, Zack is a fairly powerful character, since he's a First Class SOLDIER. This will give him an upper hand during the brutal Hashira training courses.
9 Lightning's Commitment To Saving Others Will Motivate Her As A Hashira (Final Fantasy XIII)
Part of Lightning's growth in Final Fantasy XIII was to understand her role as a savior and to allow herself to get close to others. Demon Slayer's Hashira have all been traumatized by demons and understand the importance of making sure others are spared from the same fate. Lightning's experience makes her prepared to take on the same hardships that Hashira agree to bear. Furthermore, she's a Gunblade user, which is a weapon reserved for only the strongest soldiers.
8 Ramza Beoulve's Devotion To Justice Will Guide Him As A Hashira (Final Fantasy Tactics)
Ramza prides himself as someone who always does the right thing, regardless of the consequences. He goes as far as renouncing his own family name as he finds out that the Beoulves were complicit with unjust actions. Ramza's refusal to participate in political manipulation even got his name stricken from the history of Ivalice, even though he played a key role in defeating Ultima and saving Ivalice. Ramza is also a skilled swordsman with extensive training, so he'll be able to keep up with the other Hashira.
7 Terra Branford's Esper Powers Will Be A Boon To The Hashira (Final Fantasy VI)
Half-human and half-esper, Terra is an exceptionally powerful character. Despite this, Terra is known for being afraid of her power and is reluctant to use it in battle. Being a Hashira will offer Terra a meaningful outlet for her powers since the Twelve Kizuki, and Muzan by extension, are incredibly powerful demons.
Terra will also be motivated by the fact that she'll be protecting others from being murdered by demons. She's a very versatile fighter who's also handy with a blade.
6 Gladiolus Amicitia's Sense Of Responsibility Is Crucial For A Hashira (Final Fantasy XV)
Being a Hashira isn't for the faint of heart and only those truly dedicated to bringing down Muzan will be able to weather the struggle. Gladiolus is a man who isn't afraid to speak his mind and takes his missions seriously. He even argues with Noctis, the future king he's sworn to protect, whenever he sees Noctis showing weakness toward his goals. Gladiolus's honest and direct attitude will be welcome among the Hashira since these traits make him a trustworthy man. Gladiolus also comes from a military background, so he'll be able to withstand the severe Hashira training regimens.
5 Yuna's Spiritual Background Will Fortify Her Strength As A Hashira (Final Fantasy X)
Yuna was born and raised to be a Summoner, meaning she's very devout when it comes to her responsibilities. This is a trait also shown by the Stone Hashira, Gyomei Himejima, who grew up in a Buddhist temple. Yuna's faith drives her throughout the story of Final Fantasy X. She's kind and concerned about others, which is an attribute that's sure to carry her far as a Hashira. She might not be a sword wielder, but she's got powerful aeons to back her up.
4 Sephiroth's Raw Strength Will Make Him An Asset To The Hashira (Final Fantasy VII)
Before Sephiroth went insane, he was a well-put-together young man whose power was the envy of his comrades. Although Sephiroth's superhuman ability leads him to be a bit arrogant, he's still a dedicated First Class SOLDIER who puts in his best effort. It's easy to imagine him among the ranks of the Hashira considering his skills and swordsmanship. His strength is something that will instill confidence in his teammates and inspire them to give it their all, just as it inspired the likes of Zack.
3 Shantotto's Diligence Will Keep Her Focused As A Hashira (Final Fantasy XI)
Shantotto is a Final Fantasy XI fan-favorite NPC who eventually made her way into the Dissidia: Final Fantasy series. She's a powerful black mage who's driven by her goals and thirst for knowledge. Considering the Hashira have very little information on Muzan, it's likely that Shantotto would dedicate herself fully to finding out as much as possible about him.
She might be a Tarutaru, but her small size doesn't stop her from casting extremely powerful Black magicks, so she's more than prepared to defend herself against demons.
2 Auron's Sense Of Loyalty Will Drive Him Toward His Goals As A Hashira (Final Fantasy X)
Auron is already something of a samurai himself, meaning he'll fit in great among the other Hashira. Auron was so loyal to Braska that he couldn't accept the futility of Braska's death. His loyalty to Braska's cause resulted in his spirit being bound to the mortal realm, so he roams as an unsent until he gets the opportunity to guard Braska's daughter Yuna on her own pilgrimage. Auron is a man who will stand his ground and protect his comrades no matter what.
1 Y'shtola Rhul's Composure Will Provide Wisdom To The Hashira (Final Fantasy XIV)
Like Shantotto, Y'shtola has become a fan-favorite character who represents Final Fantasy XIV in Dissidia: Final Fantasy NT. She's a no-nonsense, level-headed Scion who's devoted to the pursuit of knowledge. Her wit and insight make her a dependable teammate and strategist, allowing her to be an advantage to the other Hashira as well. Furthermore, Y'shtola has proven herself an exceptionally patient woman, so she's sure to handle any disagreements or bickering with poise. She's also a skilled mage who can practice both Black and White magic.
