Toko Agatsuma ( (あが) (つま) (とう) () Agatsuma Tōko?) is the great-granddaughter of Zenitsu Agatsuma and Nezuko Kamado and the older sister of Yoshiteru Agatsuma.


Toko bears great resemblance to her ancestor, Nezuko Kamado, having the same waist-length black hair parted to the left side of her forehead, though her hair tips are much darker than her ancestor's and are closer to actual red color than Nezuko's orange. She has round, pink eyes with prominent eyelashes and thin eyebrows.

Toko wears her school's standard uniform, consisting of a light blue long-sleeved shirt, black skirt, black ribbon necktie, and white vest. She also sports her uniform's black knee-socks and brown student shoes.


Towards her brother, Toko shows great aggravation and animosity, often berating him for his antics and telling him off for not studying. At times, she resorts to physically attacking Yoshiteru, such as kicking his back or tugging on his ear.[2]

However, when Toko is with Kanata Kamado, she instantly loses her angry demeanor and instead becomes much more jubilant, especially if Kanata compliments her.[3] She is still easily annoyed by her brother if he interrupts her and Kanata's activities.[4]

Toko's personality shows that she doesn't believe in "superstitious" things, such as Zenitsu's journal about their journey to fight back the demons.



Yoshiteru Agatsuma

As an older sister, Toko is always telling off him to focus on his study, especially when Yoshiteru was reading Zenitsu's book. Although she was always angry at him, both Yoshiteru and Toko care for each other, showing they have a good relationship.

Kanata Kamado

Kanata is Toko's third cousin. When around him, she often switches to a happier personality instead of her angry demeanor, and they often compliment each other. Toko appears to enjoy holding his hand.

Abilities and Powers

As an ordinary human, Toko does not hold any special abilities or powers.


  • Her first name contains the kanji for "lamp" (燈 tou) and (子 ko) which is a "word that comes after a woman's name, child". Her surname means "my wife" (我妻 agatsuma?).
