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.
The amount of Wisteria poison in Shinobu's body was originally stated to be seventy times the lethal amount to kill a demon in the magazine version, but it was later corrected by Koyoharu Gotoge to be seven hundred times in the volume edition.
She is the only one of them who does not slay demons by beheading them, instead, she injects a deadly poison into her foes using her blade.
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.
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.
In preparation against Doma, Shinobu willingly altered her own physiology so that every single cell of her flesh was coated in Wisteria Poison, with her body effectively becoming a undetectable, human poison capsule that would slowly destroy the body of even the highest Upper Ranks of the Twelve Kizuki with enough time ...
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.
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.
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.
Shinobu holds a strong resentment and hatred for Doma, due to him killing her older sister, Kanae.
In her inital appearance, Shinobu was completely mute, not speaking at all, except for a few occasions. Even so, she is normally very talkative, and could not stand being silent for more than a few months. She has a haughty and arrogant demeanor, being very prideful and overly confident in her own abilities.
Giyu points out that Shinobu can't stand cats, dogs, and pretty much any animal with fur, although she denies it. According to Shinobu, the first one among them to speak gets to greet the Master, Kagaya Ubuyashiki, so they all had butterflies in their stomachs until their Master arrived.
5/14 Fastest Hashira In Running
Despite his large and muscular build, Tengen Uzui is the fastest runner among the Hashira.
Unfortunately, Shinobu is fairly small with small arms, so it is physically impossible for her to behead a demon in a single strike. Not only that, the Flower Breathing technique itself is quite a physically demanding technique.
Absorption: Doma is able to completely absorb and devour an entire human body without eating them, having completely broken down and incorporated Shinobu Kocho's body into his own within only a few seconds after killing her.
Doma also displayed what arguably is his first true emotion, love, when he proclaimed his love for Shinobu after finding her cute.
8/13 Shinobu Kocho, The Insect Hashira

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 . ...
Shinobu appears to be of African-American descent with her hair styled into a white afro that has a flower decoration in it and wears a school uniform, though her classmates don't seem to wear a uniform. Her sword also seems to have trinkets similar to cell-phone charms on the scabbard.
