Rengoku- Agoraphobia the fear of situations in which escape is difficult. Obanai- thanatophobia the fear of someone they love dies (broskie wants to make sure Mitsuri is immortal and frankly so do I :( )
Tengen Uzui
He is the fastest Hashira, and the second physically strongest. Obviously, then, Tengen Uzui is rather proud. He is demanding, fussy, boastful, and prone to selfishness. But he is also ultimately kind and caring, with great love for his three wives as well as the other Hashira.
This is certainly surprising that a character as strong as Arataki Itto is scared of Kuki Shinobu. In his story quest, it was evident that Itto takes on every challenge without fear, but from the looks of it, even he wouldn't like to face an angry Shinobu.
He was also the youngest of the Hashira at only 14 years old, being considered a prodigy of the Corps who became a Hashira only two months after joining the Demon Slayers. Muichiro, like the other Hashira, was involved in the raid on Muzan Kibutsuji's headquarters - the Dimensional Infinity Fortress.
To Fulfill The Promise to His Mother. Another big reason why Kyojuro is so determined on becoming the Flame Hashira was because of his promise to his late mother, Ruka Rengoku. Ruka was a woman who had a very strong sense of justice.
Shizuka is seen often teasing Sanemi and making him annoyed, nevertheless, the two had still created a strong bond and relationship with each other. Eventually, after knowing each other for a while, Shizuka finally ended up having the courage and confessed, leading to them getting married after awhile.
Demon Slayer has peculiar characters with incredible strength, skill, and presence. But, among this group of eccentric people, Kyojuro Rengoku still stands out from his colleagues due to his upright and exceptional bright personality. Yet, his fiery hair is also one of the biggest reasons he stands out.
12 Tengen Uzui
The Sound Hashira is the second oldest out of the main Demon Slayer cast. Tengen's uniqueness shows in both his appearance and personality, but he can still hold his own as a Hashira.
Overall Abilities: As a Hashira of the Demon Slayer Corps, Gyomei is a very powerful and skilled combatant. He is stated by both Tanjiro and Inosuke to be the strongest Demon Slayer in the entire Demon Slayer Corps. As stated by Tengen Uzui, Gyomei gained the rank of a Hashira in a mere two months.
Rengoku- Agoraphobia the fear of situations in which escape is difficult.
In fanon they usually portray Douma being comically in love with Shinobu while she despises him, or they both falling in love with each other and developing a romantic relationship despite Shinobu's initial reluctance.
Apart from her strongest feats, she is loved for her easygoing smile, which she continues to maintain even if the situation is not in her favor. However, later in the series, it was revealed that Shinobu's smile is nothing but a facade.
Rengoku's fight in the Mugen Train arc showed his incredible speed and reflexes. He was able to match Akaza's speed, and his movements were so fast that it was almost impossible for the naked eye to keep up. Tengen, meanwhile, is the fastest runner out of all the Hashira.
Shinobu Kocho is a capable Demon Slayer whose worthy of being the Insect Hashira. That being said, she's arguably the weakest Hashira when it comes to pure strength.
1. Gyomei Himejima. Gyomei Himejima, the Stone Hashira, is the strongest Hashira in the Demon Slayer corps in terms of strength and swordsmanship. He is the only person who uses spiked flails and an axe instead of standard swords to kill demons.
Rengoku died at the end of the Mugen Train arc. He succumbed to his wounds after realizing that he didn't stand a chance against Akaza, who shamelessly fled the scene as soon as the sun came up. Rengoku died smiling, but not before giving Tanjiro some words of encouragement.
The Water Hashira, Giyu, survived the "Infinity Castle" arc after fighting beside Tanjiro against Akaza and Muzan.
Being a demon, Muzan is capable of living for many, many years. However, unlike other demons that have aged over hundreds of years. Muzan is well over 1000 years old.
Tanjiro's Age as Demon Slayer's Shonen Protagonist
When Demon Slayer's story begins in Chapter/Episode 1, Tanjiro Kamado is 13 years old, which is younger than usual for many shonen heroes.
While stuck physically at age 12 because of the whole demon thing, Nezuko is 14 chronologically. Can Nezuko change her age? Due to her demon abilities, Nezuko can change her size/age and appear “mature” in a slightly older form or can even make herself look younger and smaller than a 12-year-old.
However, due to her condition, Nezuko doesn't age physically. So her body retains the semi-demon, semi-human appearance it developed when she was transformed. So while Nezuko maintains her 12-year-old body, she has lived for 14 years.
1 Kyojuro 'Flame Pillar' Rengoku
And finally, let's get to the number one saddest death in the franchise, and of course, that's the death of the brightly burning Flame-Breathing user that is Kyojuro Rengoku.
The fact is, Kyojuro Rengoku is just a really good guy. He's the type of character who is easy to relate to. His strength of will and determination despite his trials, his firm belief in his ideals, alongside his strength.
Rengoku's Unwavering Will Was His Greatest Weakness
Since he believes it is his responsibility as someone strong to protect those weaker than him, he will make sure he does just that. Rengoku sees any mission through to the very end, even at the cost of his life.
