Shinobu's name, Shinobu (しのぶ,Shinobu?) is a Japanese verb meaning "recall" (偲ぶ, "recall"?) or "stealth/endure" (忍ぶ,"stealth/endure"?).Her name is spelled with three hiragana characters, which differs from the way Kanae's and Kanao's names are written.The engravings on Shinobu's sword read "evil demon" (悪鬼, akki?)[22] on the right side of the blade, and "destroy/kill" (滅殺, messatsu?) on the left side of the blade.[2]Shinobu's surname means "butterfly"(胡こち蝶ょう, kochō?).Shinobu was ranked 6th place in the first character popularity poll with 1,813 votes.Both of Shinobu's voice actors, Saori Hayami and Erika Harlacher, also share the roles of Emi Igawa from Your Lie in April, Yumeko Jabami from Kakeguruiand Therese Alexanderite from The Rising of the Shield Hero.Her 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 of the uniform instead.[23]Shinobu and Mitsuri get along quite well due to them having been the only two female Hashira after Kanae's death. Mitsuri also teaches her western cooking.[24]Her parents worked in compounding medicine, a reason why Shinobu is also very talented with medicines.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 Gotōgeto be seven hundred times in the volume edition.[21]Shinobu's blade was designed and created by the chief of the Swordsmith Village, Tecchin Tecchikawahara.[25]There was some tension during the cooperative research time between Shinobu and Yushiro. Shinobu held some distrust towards Tamayo due to her being a Demon, and Yushiro wished to kill Shinobu as a result of it.[21]
