Toko Agatsuma

Toko Agatsuma is the great-granddaughter of Zenitsu Agatsuma and Nezuko Kamado. She is also the older sister of Yoshiteru Agatsuma.

Appearance
Toko bears a 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 an 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 loafers.

Personality
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.

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

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

Synopsis
When Yoshiteru was reading Zenitsu's memoir, Toko appeared from behind with a kick to his back, scolding him for reading Zenitsu's fabricated memoir. She then scolds Yoshiteru for his lack of studying, partly due to his recent low grades. Although Yoshiteru defended him selfby saying how his great-grandfather risked his life to fight, Toko pinched his ear and forced him to study properly so as not to dishonor his great-grandfather.

On the way to school, Yoshiteru, with an extremely annoyed attitude when he was scolded and beaten by his sister, thinks that Toko is different from all the women in the family because of her hot temper. Yoshiteru then asked Toko if she believed in reincarnation, but as someone who was not superstitious, Toko scolded Yoshiteru immediately. After apologizing to her, he expressed his thoughts that those who fell to fight the demons have now been reincarnated and will live happier lives than before. But then Toko immediately ignored it and opened her phone to see the notification, she was immediately noticed with the latest news about an athlete named Tenma Uzui, who won a gold medal in gymnastics. Despite being criticized by Yoshiteru as a thug and rude, Toko defended Tenma. Toko was then snatched by her brother to see a news item about a botanist named Hashibira Aoba. Seeing her younger brother praising Aoba as a beauty, Toko immediately called it a boy and mocked Yoshiteru for being lustful like their father. While crossing the street, Toko and his younger brother met a pair of twins who looked like Yuichiro Tokito and Muichiro Tokito, due to discovering his brother had evil intentions, Toko immediately told him disgusting. With that same displeasure, she continued to look at Yoshiteru as he watched two female students who looked like Kanae Kocho and Shinobu Kocho from Sekirei Academy.

At that moment, Toko spotted Kanata Kamado, her cousin, and said good morning with an extremely amused expression on her face. After receiving compliments from Kanata, Toko's personality changed, she became softer and seemed quite shy around Kanata. Later, Toko invited Kanata to go to a restaurant of a couple who looked quite similar to Mitsuri Kanroji and Obanai Iguro, but after hearing Kanata's story and discovered that his younger brother was who made Toko and Kanata unable to go to that restaurant, she turned around, with a very angry expression, and looked at Yoshiteru.
