Shinobu's Demon Slayer uniform's jacket is originally designed to leave the center of the chest area open, similar to Mitsuri Kanroji's, but, as Shinobu disliked this aspect of its design, she burned the original uniform right in front of the Kakushi who had just given it to her and requested a fully buttoned version ...
It is revealed in an omake that her current uniform is made by a Kakushi member; who also initially gave the same design to Shinobu, Kanao, and Aoi. Although unlike the others who burned their uniforms, Mitsuri opted to keep wearing it, as she couldn't manage to burn her uniform as well.
On the back of the shirt is a large kanji character in white, ”滅” (metsu, meaning extermination), representing the "metsu" in the Demon Slayer Corps name in Japanese which is kimetsutai (鬼滅隊 ). The hakama pants are also a simple all black color.
Shinobu has two outfits in Bakemonogatari, though they're really two versions of the same outfit. In this part of the series, she wears a pink dress with white frills on the chest area and a red ribbon around the waist. The skirt of the dress also has a white inner lining.
The socks were given as a present because Mitsuri was very embarrassed and fidgety about using her uniform.
He is partially blind as he can barely see out of his right eye. Obanai's mouth is also unusual in that, when he was twelve, it was cut from its corners to his ears to make it appear more like that of a snake, leaving a large wound that he keeps hidden under the bandage he wears over his lower face.
Tanjiro is glad to see him, but is quickly horrified when he realises Obanai's face is mutilated. Obanai explains that the earlier attack by Muzan's leg whips was the one that injured him.
Keen Intellect: Shinobu possesses vast knowledge in using poison in combat. She has one of the best IQ in the Corps, having an IQ of over 200 making her a genius.
Shinobu holds a strong resentment and hatred for Doma, due to him killing her older sister, Kanae.
However, her playful attitude is revealed to be fake—in reality, Shinobu holds a deep, intense hatred for demons due to almost all of her loved ones (her sister, her parents, and almost all of her tsuguko) being killed by them, so much so that she is in a near-constant state of anger.
Poisonous Physiology: In order to defeat Doma, Shinobu heavily altered her body by absorbing highly concentrated Wisteria-based poison over a period of a year prior to her battle with him.
Poisonous Body: In order to defeat Upper Moon Two, Doma who killed her sister, Shinobu heavily transformed her body by absorbing and altering her body's physiology with highly concentrated wisteria based poison.
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.
Mitsuri is a voluptuous young woman with a kind face. She has pale green eyes with small moles under each eye. Her most defining feature would be her long hair usually tied in three braids which is pink and fades into neon green halfway through.
Mitsuri's Breathing Style is Love Breathing, a bit odd-sounding next to Styles that draw on nature such as Water Breathing and Thunder Breathing.
Appearance. Mitsuri Kanroji is a young woman with bright green eyes, with long eyelashes and a small mole. She has long pink hair mixed with neon-green paint, wearing three thick braids and five shorter clumps falling over her nose like bangs.
Doma also displayed what arguably is his first true emotion, love, when he proclaimed his love for Shinobu after finding her cute.
When Shutaro Mendo arrives at their school, Shinobu, like all the other girls in class, develops a crush on him at first sight. This causes her to question her feelings for Ataru, and turns the love triangle of her, Ataru and Lum, into a four-way entanglement.
When Giyu later hears about Shinobu's death, he suddenly recalls her smiling face while being visibly shocked and upset by the news. This contrasts to his reaction to death of his other fellow Demon Slayers such as Kyojuro Rengoku, Muichiro Tokito and Genya Shinazugawa, whom he didn't react to as emotionally.
As the self-proclaimed weakest Hashira of the Demon Slayers Corps, Shinobu Kocho makes no attempt to appear stronger than she actually is. Instead, like many weak anime heroes, Shinobu balances out her weakness with cleverness and skill.
When he was 12 years old, Obanai was taken outside to be presented to the Demon and was forced to have his mouth cut by his family to look similar to the snake Demon.
He has sharp pointed eyes with unusual eye colors due to him having heterochromia. His right eye is yellow and his left eye is turquoise. Obanai's lower half of his face is covered in bandages to hide his mouth which was cut from the corners of his lips to his ears to appear snake-like.
