I just caught up in the anime, and one thing is really bothering me. Having a phobia of sharp objects probably makes it hard to use a sword, no?
Shinobu also probably has Domaphobia (fear of Doma)
Personality. Shinobu always has a pleasant expression on her face and is first thought to be laid back and friendly, wanting to establish some peace between humans and Demons. It is later revealed that she hates Demons with a burning passion after a Demons killed her parents and her older sister.
Shinobu can't stand any kinds of furry creatures, according to Giyu Tomioka.
Although Giyu maintains a cold and distant stance, among all the pillars, Shinobu is the one who understands him the most and has the best relationship with him. Shinobu says that Giyuu is hated by other people, which can seem mean, but in reality she actually supports him.
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.
Shinobu holds a strong resentment and hatred for Doma, due to him killing her older sister, Kanae.
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.
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.
Makomo's being Lesbian, Shinobu's being Bisexual and Mitsuri's being Bisexual or Pansexual.
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.
Giyu points out that Shinobu can't stand cats, dogs, and pretty much any animal with fur, although she denies it.
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.
Shinobu dons the standard Demon Slayer uniform that consists of a dark purple straight-lined jacket, and hakama pants tucked into butterfly patterned fabric around her lower legs that match her haori.
Shinobu is defeated and absorbed by Doma.
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.
Demon Slayer's Tengen Uzui is considered to be one of the weakest Hashira due to almost losing this fight, but the fact is that Tengen only looks weak when compared to the most overpowered Hashira.
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 wears a black midriff with a purple jacket, gloves, and wears shorts with long sandals with magenta knee armor and wears nail polish on her fingers and toes. She also have a tattoo on her backside.
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.
Tl;dr: While Shinobu does tease Giyuu quite a bit, she doesn't enjoy bullying him - instead she taunts him as a way of letting her frustrations out while carrying on Kanae's memory/wishes.
Shinobu opened her mouth and Giyuu did so as well, deepening the kiss. Giyuu was huffing little puffs of breath between kisses, while Shinobu's lips were quirked in mirth at how affected Giyuu already was.
