Daki/Relationships

Gyutaro
Gyutaro is Daki's brother, and Daki is seen taking advantage of his power and overprotectiveness of her in order to attempt to defeat the Demon Slayers. She often acts bratty around him, crying to him when things don't work out and expecting him to finish jobs for her, and she'll even ridicule him when he's unable to do this. Despite this, however, she's been shown to genuinely reciprocate his feelings of love towards her. Even in death, she refuses to leave Gyutaro alone and stubbornly insists on following him even to hell. She believes that they're at their strongest when together, and that no matter how many times she dies and is reborn, she will always be his little sister.

Muzan Kibutsuji
Daki is faultlessly loyal to Muzan to the point at which it's almost obsessive. She drops her usual prideful demeanor around him and will act very meek when talking to him, seemingly transfixed by his prescience.

Muzan himself never thought highly of Daki and didn't reciprocate her devotion whatsoever, only ever talking to her to sweetly manipulate her into defeating Demon Slayers on his behalf.

Tanjiro Kamado
Daki was enraged by Tanjiro when he told her to let Koinatsu go. Although she considered Tanjiro to be ugly, she complimented him a few times, most notably when she said that he had nice eyes.

Zenitsu Agatsuma
When Zenitsu attempted to stop Daki from hurting a child, she was disgusted by him. Immediately after the children thank Zenitsu for saving them from Daki, she uses her sashes to trap Zenitsu in her belt.

Inosuke Hashibira
Daki views Inosuke as an annoyance, due to him breaking into her foodlocker and releasing the stored humans she intended to eat. Never the less, she acknowledges that he has a very beautiful face and intended to capture him alive for later consumption, due to her penchant for only eating people that she views as exceptionally beautiful.
