Sakonji Urokodaki is one of the playable characters in Demon Slayer: The Hinokami Chronicles. A former member of the Demon Slayer Corps, Urokodaki is Tanjiro's master and he was also the master of Sabito and Makomo before they died.
Giyu Tomioka is the stoic swordsman that fights using his "Water Breathing", and the Water Hashira that led Tanjiro towards joining the Demon Slayer Corps. The man in the tengu mask. He's a cultivator of prospective Demon Slayers, who lives at the foot of Mount Sagiri, and the one that trained Tanjiro.
Giyu was the first Hashira to be introduced in the series, making his debut in the very first episode. After rescuing Tanjiro from the newly transformed demon Nezuko, Giyu prepares to execute her as he would any other demon.
Sakonji Urokodaki ( 鱗 うろこ 瀧 だき 左 さ 近 こん 次 じ , Urokodaki Sakonji?) is a retired member of the Demon Slayer Corps, having held the position of the previous Water Hashira ( 水 みず 柱 ばしら , Mizu Bashira?).
Thus, Tanjiro became one of the first Demon Slayers to ever kill an Upper Rank, a feat that hasn't been accomplished for the last century.
No, they are not related. Tanjiro, by PURE COINCIDENCE, heavily resembles Yoriichi Tsugikuni, the creator of Breath swordsmanship, the only other person to use Sun Breathing, and the only person Muzan ever feared.
Zenitsu Agatsuma
She apparently views Zenitsu as a "weird dandelion" and did not initially seem to reciprocate his feelings. Although the two are rarely seen interacting together, Zenitsu treats her with affection and care.
Kazuhirō Sasaki, Darkness Hashira.
With his growing fondness for them, Tengen Uzui proudly claimed Tanjiro, Zenitsu, and Inosuke as his Tsuguko when they entered the fight.
He is one of the show "top protagonists", standing effortlessly over his fellow Hashira. He is extremely muscular and powerfully built. He has black spiky hair, and a prominent scar that runs across his forehead horizontally. He has been blind with no irises nor pupils.
He does not think of himself as a true Hashira, despite mastering Water Breathing as he considered his fellow apprentice Sabito, who died saving other Demon Slayers-in-training, more suited for the role.
When it comes to pure strength, Shinobu Kocho is the weakest Hashira in Demon Slayer. She doesn't even have enough strength to decapitate a demon's head and she makes up for it by injecting poison into the demons.
Mitsuri is a curvaceous young woman of average height and muscular build with a slightly pale complexion and round, pale green eyes with long eyelashes, a small beauty mark beneath each of them. She has long, light pink hair that fades into a lime green color at the halfway point, which she wears in three thick braids.
He is a former member of the Demon Slayer Corps, as well as the previous Water Hashira. He is also the teacher of Tanjiro Kamado, Giyu Tomioka, Sabito, and Makomo.
Master Swordsmith: Hotaru is a skilled swordsmith, able to forge the Nichirin Sword and repaired it multiple times each time it broke against the Lower and Upper Ranks. After Tanjiro chipped his sword in his battle against Upper Rank Six, Gyutaro and Daki, Hotaru trained more to make a stronger sword.
That being said, Tanjiro's rank is unknown, and his rank was last revealed in the Entertainment District arc. In that arc, they were at Kanoe, which is fourth from the bottom. Since Kiriya Ubuyashiki announced the disbanding of the organization, Tanjiro doesn't get the chance to become a Hashira.
Sound Hashira
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 fact built his inferiority complex that made him feel unsuitable for a position as a Hashira, persuading him that Sabito would've likely received the mark rather than himself. Giyu's memories of Sabito.
2) Sanemi Shinazugawa
His fast movement, combined with his excellent swordsmanship, makes him a remarkable demon slayer. Most of his attacks are purely offensive due to his breathing style. Being a user of wind breathing, he is undoubtedly fast.
Yukire Hanazawa ( 花沢 はなざわ 雪 ゆき れ, Hanazawa Yukire?) is a Demon Slayer and the Ice Hashira ( 氷 こおり 柱 ばしら , Kōri Bashira?) of the Demon Slayer Corps.
Muichiro Tokito (時透 無一郎) was a major supporting character in the 2016 fantasy horror manga and anime series Demon Slayer: Kimetsu no Yaiba. He was one of the nine Hashira, a group of the nine greatest Demon Slayers in the Demon Slayer Corps.
Nezuko Kamado
Zenitsu also protects Nezuko multiple times when she is in danger, evident during Zenitsu's first meeting with Inosuke Hashibira and the battle against Enmu in the train. Eventually Zenitsu and Nezuko would marry and start a family as evidenced by their descendants.
Zenitsu's debt is estimated to be around 600,000 yen in modern currency. This massive amount of debt likely came from his 7 ex-girlfriends.
