I can't believe you broke my sword! I can't believe it! [...] I don't care! That doesn't matter! It's your fault! It's all your fault! The katana broke because you were weak! Otherwise, would my katana break?! I'm going to kill you!
 
Hotaru blaming Tanjiro for breaking his sword in The Nichirin Sword Returns

Hotaru Haganezuka (鋼鐵 (はがね) (づか) (ほたる) Haganezuka Hotaru?) is a supporting character of Demon Slayer: Kimetsu no Yaiba. He is a swordsmith affiliated with the Demon Slayer Corps.

Appearance[]

Hotaru wears a sunflower-patterned haori and has his head wrapped in a spotted head scarf. Like the rest of the swordsmiths, his face is concealed by a Hyottoko mask (wooden festival mask) to conceal his identity. When traveling he wears a large, woven hat with hanging floral wind chimes on top of the head scarf.

During the Swordsmith Village Arc, he is seen with a more muscular build compared to his initial appearance after he had been training in the mountains.[3]

Unmasked, Hotaru is revealed to have long, black hair coupled with sharp eyes and distinctly-shaped thick eyebrows.[4] However upon being attacked by Upper Rank Five, Gyokko, Hotaru now possesses several deep scars and cuts from the demon all over his body, including an X-shaped one on his face, and has now lost the use of his left eye.

Personality[]

Hotaru's hot-blooded and fiery personality.

Hotaru is a rather hot-blooded individual. He seems to show very little care, if any, about anything besides the swords he creates. His passion for swords is so strong that he would be able to speak about them for long periods of time, a trait unique even among other swordsmiths.

The same passion that gives him the enthusiasm and extreme dedication in creating swords is also the reason why he is easily enraged (usually in a comical fashion) towards swordsmen that break his creations, especially Tanjiro Kamado, no matter the circumstance.[5] When angry, he usually calms himself down by eating mitarashi dango. Bystanders can subdue him by either pinning him down or tickling his sides, as demonstrated by Kozo Kanamori, after which he will fall limp.[6]

As Hotaru is socially inept in dealing with people, he is still unmarried. His intense and asocial behavior also causes other swordsmen to hate him and he lost a lot of clients because of this. Although he won't be honest about it, he is actually happy that Tanjiro still trusts him in making his swords.[7]

His concentration on sword-making is so immense that it prevents him from paying any attention to his surroundings when forging a blade, even when a demon is attacking him and inflicting severe injuries on him.[8] When the process of forging or refining is interrupted by taking the sword away, he feels the need to restart the whole process from scratch again. As a perfectionist, any small scratch on a blade that is irremovable hurts him immensely.[9]

Despite his notorious asocial and volatile personality, he shows a more surprisingly pacified and rational side when a woman that Kozo, Tecchin, and Kotetsu attempted to matchmake with Hotaru degrades swords as antiquated and barbaric. Hotaru points out the perseverance that Demon Slayers display and the daily risks they face and proclaims that he is proud to forge swords for them, and frankly turns her down. This shows that despite his unruly personality, Hotaru does have a deep respect for the Demon Slayers. [2]

History[]

Hotaru was born from a long line of swordsmiths from the Haganezuka Clan.[10] When he was two years old, Hotaru was so horrible to deal with that his parents had a mental breakdown[2] and the village's chief, Tecchin Tecchikawahara, had to raise him.[11] The chief gave Hotaru his first name, which Hotaru does not like, because it sounds too cute and he would often badmouth the chief about it. According to the chief, he had been having a temper since he was a child, and would always throw tantrums right away and then go off somewhere.[10]

Learning the craftsmanship of sword making from the other swordsmiths, he also became a swordsmith that forges and polishes Nichirin Swords for the Demon Slayers. After Tanjiro successfully survived the Final Selection, Hotaru was assigned by the Corps to forge Tanjiro's sword.

Synopsis[]

Final Selection Arc[]

Hotaru meeting Tanjiro

Hotaru meets Tanjiro Kamado.

Hotaru first appears at Sakonji Urokodaki's house to deliver Tanjiro's Nichirin Sword after the latter passed the Final Selection.[12] Despite Tanjiro's frequent requests for him to enter the house, Hotaru ignores him and sits outside the door, describing the blade he forged.

After suddenly looking up at Tanjiro, he comments on his red hair and eyes, stating it was good fortune. Excited, Hotaru enters the house while remarking how Nichirin swords would change color and that his sword could turn a bright red, however, after seeing the blade turn jet black, Hotaru shows evident disappointment and gets angry at Tanjiro.[1]

Mount Natagumo Arc[]

During his fight against Lower Rank Five, Rui, Tanjiro breaks his blade and an enraged Hotaru is briefly seen in Tanjiro's thoughts as he internally apologizes to Hotaru and Urokodaki.[13]

Rehabilitation Training Arc[]

After Tanjiro heals at the Butterfly Mansion, he and Inosuke Hashibira greet their swordsmiths but are met with an angry Hotaru charging at Tanjiro with a knife, furious about his broken blade.[14] After chasing him and then calming down, Hotaru and Kozo give the swordsmen their repaired blades.

Mugen Train Arc[]

Hotaru appears when Tanjiro comes back from the Rengoku house, enraged over the loss of another sword and chases Tanjiro again.[15]

Swordsmith Village Arc[]

Hotaru's letters

The angry letters Hotaru writes to Tanjiro.

After Tanjiro wakes up from his coma after the battle against Upper Rank Six, Daki and Gyutaro, and enquires about his new sword, Kiyo Terauchi shows him the fierce letters Hotaru sent after his sword got chipped. In the letters he expressed angrily that he will not make a new sword for Tanjiro. Kiyo suggests that Tanjiro should meet Hotaru in person to discuss it.[16] Tanjiro then travels to the Swordsmith Village, but the village chief Tecchin Tecchikawahara informs him that Hotaru is missing and they are trying to locate him.[10]

When Tanjiro was arguing with Muichiro about the latter's treatment of Kotetsu, Tanjiro expresses loudly that a swordsmith’s job is extremely important and crucial. He praises swordsmiths for possessing amazing skills that are different from swordsmen, and exclaims that swordsmen and swordsmiths cannot exist without each other, fighting the same fight every day in their own way. Hotaru is hiding behind a tree listening to Tanjiro's speech and is very moved by it. After Tanjiro became unconscious from being hit by Muichiro, Hotaru appears in front of Kotetsu and offers to carry Tanjiro back down, but when Tanjiro started to come by, he immediately runs away. Tanjiro wonders if he is imagining hearing Hotaru talking.[17]

After Tanjiro trained with Yoriichi Type Zero for some time, he manages to behead it and discovers a hidden sword from 300 years ago, Hotaru suddenly appears topless and completely buffed, shocking both Tanjiro and Kotetsu. He tries to take the sword away, and the two struggle with him until he is tickled by Kozo, after which he falls limp. Kozo reveals that Hotaru had been training in the mountains to make an extremely strong sword for Tanjiro and Tanjiro is moved by it. After Hotaru wakes up he explains he will refine the rusted blade. It will take him three days and three nights to finish, and Tanjiro is worried about Hotaru's health as there are swordsmen dying from using Hotaru's method.[18]

During this period the village is attacked by two Upper Rank Demons. Upper Moon Five, Gyokko, enters the shed where Hotaru is working on the blade and slashes Kozo who desperately shields Hotaru from the demon. Unaware of their presence, Hotaru continues to fixate himself on refining the blade. When Gyokko calls out to him, Hotaru does not respond and continues muttering about the eccentricity of the blade, a level of concentration that astonishes Gyokko. Jealous of Hotaru's fixation for his craft, Gyokko slashes him multiple times, causing Hotaru's mask to fall off his face from the attack and revealing his face.

Kozo tries to snap Hotaru out of his trance, with Gyokko summoning fish demons and continue to attack Hotaru, the swordsmith still did not break his continuous persistence and keeps sharpening the blade silently.[19] This greatly infuriates Gyokko, who continues to inflict numerous severe injuries on Hotaru, including the loss of an eye. Muichiro arrives and attacks Gyokko, who then destroys the shed with his Blood Demon Art. Hotaru is knocked outside from the attack, but pays no mind to it as he returns to sharpening the blade. His stubborn persistence puzzles the demon who believes Hotaru is not sane. Gyokko tells himself he will finish the swordsmith after taking out the Hashira first.[20]

Hotaru continues sharpening the blade after being forced out of the shed

Hotaru continues to polish the blade, ignoring being thrown by Gyokko's attack.

In the ensuing fight between Gyokko and Muichiro, Hotaru and Kozo gets blasted away, but Hotaru continues sharpening the blade while lying on the ground. After Muichiro successfully defeated Gyokko, Muichiro falls down foaming and Kozo screams at Hotaru to help. Hotaru ignores him and continues working on the blade, with Kozo cursing him for not helping him earlier as well when he was almost killed by Gyokko in the shed.[21]

Hotaru's hard work proved instrumental in defeating Upper Moon Four, Hantengu. Muichiro had grabbed the sword Hotaru was sharpening and threw it towards Tanjiro, who used it to successfully decapitate the demon just in time before the sun rises. All this time, Hotaru had been screaming his objections about the sword still being unfinished and wants it back, while Kozo and Kotetsu attempt to hold him back.[22]

Hashira Training Arc[]

After Tanjiro has been resting for days after the fight in the Swordsmith Village, Hotaru arrives at the Butterfly Mansion to deliver Tanjiro his sword. The swordsmith is huffing and puffing behind his mask with visible sweat coming off the mask. He passive-aggressively urges Tanjiro to unsheathe the blade. Tanjiro is in awe by the blade. Hotaru says that it is made from high quality steel and it must have been used previously by a very strong swordsman. He theorizes that the Demon Slayer hierarchy must have been established after this blade was forged.

When Tanjiro says that he didn't remember seeing the now-visible character on the sword when he used it, Hotaru angrily explains that they took it while there was still rust covering the blade as he only finished the first stage of the process. He also claims that Tanjiro has put irremovable damage on it and therefore wants to kill him. He leaves after Tanjiro promises to bring him Mitarashi Dango until the day he dies. Tanjiro believes he treated him relatively mildly this time, because he looked like he was in pain.[9]

Abilities[]

Overall Abilities: Being a swordsmith, Hotaru initially did not appear to have any kind of superhuman abilities similar to Demon Slayers. However, after Tanjiro broke his Nichirin Sword multiple times against members of the Lower and Upper Ranks, he underwent a special solitary training regimen in the mountains so he could forge a stronger blade for Tanjiro. As such, his physique was greatly enhanced with prominent musculature, enough to even overpower Tanjiro when he pulled away a blade from his hands.[23] Additionally, Hotaru survived an onslaught of attacks by Gyokko, the Upper Rank Five, even confusing the demon with his unrelenting commitment to polishing his blade and ignoring his many injuries.

Hotaru ignores being slashed by Gyokko.

Enhanced Stamina: Mostly used as comic relief, Haganezuka has absurd amounts of stamina, evidenced by relentlessly pursuing Tanjiro for hours from evening to morning, and even made another attempt the following day. In both instances Tanjiro was left exhausted. Hotaru also survived being attacked by Gyokko's sharp tendrils of water.

Enhanced Strength: After training in the mountains, his increased strength apparently exceeded that of even Tanjiro, able to pull the ancient sword from his grasp and even shoving him to the ground.

Master Swordsmith: Hotaru is a master swordsmith, able to forge Nichirin Swords and repair it multiple times each time it broke in battles against demons. After Tanjiro chipped his sword in his battle against Upper Rank Six, Hotaru trained himself more to make a stronger sword. Hotaru demonstrated his professionalism and expertise when he polished and sharpened the 300-year-old blade left in Yoriichi Type Zero while completely ignoring the wounds he received from Gyokko.[19] The polishing techniques he used has been passed down the Haganezuka line for many generations.[2] His method is so severe that other swordsmiths have died from them.[23]

Fighting Style[]

Tantōjutsu: Hotaru is an expert in using a Tantō, though he practices the combat style with his razor-sharp knives. He usually shows his skills by attacking Tanjiro after he damages his swords.

Equipment[]

Kitchen knives: Hotary is usually armed with a pair of kitchen knives. He usually use them in anger whenever Tanjiro breaks his Nichrin Sword. According to Kotetsu, the knives are of his own make and are extremely sharp, so much so that Hotaru is afraid to use them in the kitchen.

  • (To a woman)"Those swords [...] The weapons that you call barbaric. There are men and women who pick them up to protect strangers at the cost of their own lives. [...] Even battered and beaten, they push forward, never backing down, their spirits unbroken. I'm proud to forge the swords they wield. I'm proud to be a swordsmith."[2]
