Indomitable Will: Shinobu possesses an undaunted spirit and incredible willpower, mostly due to her unquenchable hatred for demons. Even with her inferiority complex brought about by her small size and weak physical strength, and despite losing so much blood to the point she couldn't stand and not being able to breathe. After remembering her promise to Kanao and hearing Kanae's words, Shinobu remained steadfast and stood up, a feat that surprised even Doma. 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. [28]

Shinobu's younger self had a more brash, blunt and uncomplicated demeanor as seen when she and her sister rescued Kanao Tsuyuri, who she had a pointedly negative attitude towards raising. After the death of Kanae, however, Shinobu began to outwardly behave more like her sister and eventually developed her positive attitude and mannerisms to match while internally holding in her rage, which she later clarifies is fueled by her desire to continuously display the smile that her sister favored. Though never shown onscreen, Shinobu has a notable temper, namely in the way that makes even Inosuke Hashibira take notice. To Tanjiro Kamado) " How can you feel sorry for something that's killed humans? I've never heard of anything so absurd. But if that was how my sister truly felt, then I must carry it on. If there's a way not to kill these pitiful demons, I have to keep trying to come up with it. Without ever extinguishing the smile my sister said she loved..." [32] Shinobu shares her Japanese and English voice actresses as Emi Igawa from Your Lie in April, Yumeko Jabami from Kakegurui, and Therese Alexanderite from The Rising of the Shield Hero. To herself, recollecting her childhood life) " I once believed that the road of happiness continued forever and ever into the distance. When it was destroyed, I realized for the first time that it lies upon a thin sheet of glass. And just as we were saved, there were those whose happiness that haven't yet been destroyed. So I wanted to get stronger and protect them. That's what we promised each other. Even if we're weak and can't cut off demon heads, if we defeat one demon, we can save dozens of people. And if we can defeat an Upper Rank Kizuki, we can save hundreds. It isn't about whether we can or cannot do. There are things we have to do." [33] During her battle against Doma, Shinobu reveals that she also suffers from an inferiority complex due to her inferior physical abilities compared to her fellow Hashira, having been jealous of them for possessing taller or more muscular bodies than her and cursing her own body for not developing further to make her more effective in combat.

The names she came up with for Kanao Tsuyuri were so bizarre that upon seeing them, Kanae broke down into such an "EH?!" expression that even Aoi Kanzaki wasn't able to smoothen things out. [31]It is later revealed that her outwardly calm and tranquil disposition is worn as a mask, as Shinobu holds an intense hatred for demons due to the loss of her sister, Kanae Kocho, at a young age, along with the deaths of her parents, almost all of her Tsuguko, and the families of her apprentices at the Butterfly Mansion. This hatred is so strong that she is in a near-constant state of extreme anger, [8] which is sensed by Tanjiro Kamado when the two individuals hold a conversation. Her desire for revenge rendered her unable to live the normal life her sister had wished upon her, instead devoting the entirety of her energy to defeating demons.
