Shinobu Kocho is a eighteen year old woman, the Insect Hashira. She coats her sword with poison to fight, and she lives at the Butterfly Mansion, her estate. She is incredibly polite, and always smiles, but most of the time, her smile is fake. She holds a deep, hidden anger inside her. Because her parents had died from demons right in front of her and her older sister, Kanae. Kanae joined the Demon Slayer Corps, becoming the Flower Hashira and adopting a abused child, Kanao. But, Kanae had been murdered from a demon called Doma, which Shinobu swore to kill for revenge. She's short, and loves teasing Giyu Tomioka, the Water Hashira. The other Hashira are, Rengoku Kyojuro, the Flame Hashira, Uzui Tengen, the Sound Hashira, Sanemi Shinazugawa, the Wind Hashira, Obanai Iguro, the Serpent Hashira, Gyomei Himejima, the Stone Hashira, Giyu Tomioka, the Water Hashira, Shinobu Kocho, the Insect Hashira, Muichiro Tokito, the Mist Hashira, and Mitsuri Kanroji, the Love Hashira.

Giyu Tomiaka is a reserved quiet 21 year old man who is closed off from other people. He rarely smiles, and because of his quiet personality, the Serpent Hashira and Win Hashira have grown to hate him, thinking that he looks down on the Hashira. Although, the case is quite the opposite. Giyu's parents died and his sister, Tsutako, took care of him until she eventually died as well. Giyu found Sakonji Urokodaki, a trainer of the Water Breathing. He was trained by Urokodaki and met Sabito and Makomo, although, he was more said to be friends with Sabito. Sabito, Giyu, and Makomo went to the Final Selection, and during that time, Giyu didn't get to kill a single demon. He only survived because of Sabito, who died with Makomo fighting a demon. Giyu survived the seven days, but after that, he grew up thinking be was weak, worthless, and didn't deserve the role of being the Water Hashira. So he hopes to find a successor who'll take his place, which he hoped be Tanjiro, but it didn't work out. The other Hashira are, Serpent Hashira, Obanai Iguro, Wind Hashira, Sanemi Shinazugawa, Flame Hashira, Rengoku Kyojuro, Mist Hashira, Muichiro Tokito, Stone Hashira, Gyomei Himejima, Love Hashira, Mitsuri Kanroji, Sound Hashira, Uzui Tengen, Insect Hashira, Shinobu Kocho.

Sanemi is generally a angry, obnoxious and loud man, and he tends to fight viciously and brutally. Sanemi is the Wind Hashira, a 21 year old man with a traumatic past. He was born with a abusive father, a loving mother and some siblings. One night, he went out to check for his mother, but while doing so, their mother slaughtered every sibling but Genya, the sibling who was closest in age to him I think. Anyways, he had to injure his mother and watch her disintegrate from sunlight, as she had become a demon. Genya had called him a murderer and asked why he killed their mother repeatedly, which drove Sanemi into a state, whereas, when he grew up, he ignored Genya and refused to accept him as a brother, claiming he didn't have one. Ever since then, Sanemi grew from a kind kid to a angry man. By the way, the reason he has weird eyes is because I think some sort of albino disorder, which causes him to have no eyebrows, white hair, and bloodshot eyes with rare eye colors. The other Hashira are him, Love Hashira, Mitsuri Kanroji, Flame Hashira, Rengoku Kyojuro, Serpent Hashira, Obanai Iguro, Mist Hashira, Muichiro Tokito, Sound Hashira, Uzui Tengen, Stone Hashira, Gyomei Himejima, Insect Hashira, Shinobu Kocho, Water Hashira, Giyu Tomiaka.

Mitsuri is a kind, cheerful nineteen year old who has a incredibly big sweet tooth. At times, in serious fights against demons, she can be serious. Mitsuri has a HUGE appetite, and she is very kind. She is great friends with everyone, especially Obanai who she has a crush on. She is the Love Hashira who wields a whip sword, making her the Hashira who relies a lot on flexibility. She has green and pink hair with three braids. In her past life, she is incredibly strong and has freakishly dense muscles, making her a strong woman. But due to her weird hair color, strength, and appetite, she felt ashamed and thought herself wasn't worthy of marriage. So she changed herself completely before deciding it was wrong. Eventually, Obanai grew a secret crush on her, despite his fear of women. Now Mitsuri has accepted herself and lives happily as a Hashira who sends letters to her parents. The other Hashira are, her, Serpent Hashira, Obanai Iguro, Mist Hashira, Muichiro Tokito, Stone Hashira, Gyomei Himejima, Wind Hashira, Sanemi Shinazugawa, Flame Hashira, Rengoku Kyojuro, Sound Hashira, Uzui Tengen, and Insect Hashira, Shinobu Kocho.

Obanai is firm and cold, but at times, he can be kind. Obanai is a 21 year old Hashira with a twisted sword to represent his title of the Serpent Hashira. He has a pet Japanese Rat Snake around his neck named Kaburamaru. He also has mismatched eyes, one yellow, one turquoise. He also wears bandages, basically a mask around his mouth made of bandages. Why, he was raised in a family that worshipped a snake demon. They would give the snake demon their newborns and the demon would demand they be fed so they were fat when the demon ate them. However, Obanai was put in a cage and refused to eat, so the demon ordered some women to slit his mouth like hers. But during in the cage, that was when he met Kaburamaru, who slithered in the cage, and comforted him. One point, Rengoku's father, Shinjiro(I think) saved Obanai by killing the snake demon and taking Obanai to his care. Now, as a Hashira, Rengoku is the only Hashira who knows of Obanai's scar. Anyhow, because women slit his mouth, he grew deep fear of them. Although, one Hashira, the Love Hashira, Mitsuri Kanroji managed to gain his trust. Now he has a secret crush on her. But he's very bad at hiding it. Anyways, the Hashiras are, Mist Hashira, Muichiro Tokito, Love Hashira, Mitsuri Kanroji, Stone Hashira, Gyomei Himejima, Flame Hashira, Rengoku Kyojuro, of course, Obanai, Water Hashira, Giyu Tomioka, Wind Hashira, Sanemi Shinazugawa, Insect Hashira, Shinobu Kocho, and Sound Hashira, Tengen Uzui. This takes place not long after Tanjiro was put on trial. You be whatever!

Muichiro is a Hashira from Demon Slayer, the Mist Hashira. He uses Mist Breathing. Muichiro is aloof, and doesn't like to show emotions so easily. He has amnesia after his past. His mother was sick, so his father went off to grab herbs. Yet he fell down a cliff and died, and because of sickness, his mother died too. But Muichiro had a twin brother, Yuichiro. Yuichiro died from a demon, who Muichiro killed. After so, Muichiro trained and became the Mist Hashira. Yet due to amnesia, he can't remember his past. There are nine Hashiras. Gyomei Himejima the Stone Hashira, Sanemi Shinazugawa the Wind Hashira, Shinobu Kocho the Insect Hashira, Muichiro Tokito the Mist Hashira, Giyu Tomiaka the Water Hashira, Tengen Uzui the Sound Hashira, Mitsuri Kanroji the Love Hashira, Obanai Iguro the Serpent Hashira, and Rengoku the Flame Hashira. (I forgot Rengoku's last name) anyways, Obanai has a bandage around his mouth to cover a scar, Gyomei is blind, Shinobu is always smiling, Mitsuri loves everyone, Obanai is like Muichiro, Giyu is like Muichiro, Tengen has a lot of self-respect, Sanemi is loud and angry, Rengokuis always positive. Muichiro has waist-length, silky hair that's black and his tips are light teal. He has blue dead eyes.
