Yoriko Kuroiwa

Yoriko Kosaka (小坂 依子, Kosaka Yoriko) is a human and was Touka's best friend when they attended Kiyomi High School together. She loves to cook and hopes to become a chef someday.

She is now working as a waitress in a bakery, and is an acquaintance of Takeomi Kuroiwa.

Appearance
She has short hazelnut hair in a bob-cut and blunt bangs. She has a very kind and pleasant demeanor, always seen wearing her school uniform and a warm smile.

After the time skip, she seems to have shortened her hair now barely passing her ears as it's being held back by a bandanna.

Personality
A friendly, sweet and caring girl who is Touka's classmate and only human friend. Yoriko strives to become a cook. However, as ghouls cannot eat human food, her refined cooking tastes, normally tasty to humans, tastes even more horrible to ghouls than standard food. She cares deeply for Touka and worries over her. In return, Touka holds her in high regards and surprisingly cares deeply for her too; much like Kaneki with Hide.

Doves' Emergence
When Touka got sick, Yoriko delivered food to Touka's residence, and discovers Kaneki at her place, mistaking him for Touka's boyfriend.

Owl Suppression Operation
Yoriko and Touka make plans to visit the zoo during summer break. After the Anteiku Raid, Yoriko goes to the zoo alone to wait for Touka.

Root A (Anime)
In the Root A Anime Yoriko spends most of her time helping Touka prepare for her university entrance exams.

Rose Extermination
As Shirazu and Takeomi go to a bakery (on Saiko's pleading because she was hungry and said there was a delicious bakery nearby), Yoriko is seen holding a tray of baked rolls, calling out Takeomi. She adds quietly to herself; "That figures" when Shirazu asks Takeomi if he knows her he simply calls her by her last name.

Powers and Abilities
Yoriko is an ordinary human, living a peaceful life. Her only notable skill is her exceptional cooking.

Touka Kirishima
Yoriko has been close to Touka for a long time and she seems to support Touka in the same way Hide does with Kaneki. Touka also cares deeply for her friend and defended her against some classmates who tried to bully her. Yoriko is not aware that Touka is a ghoul, however, and often brings her food or tries to get Touka to eat with her at lunch.

Since the destruction of Anteiku, it is unknown whether she knows what became of Touka or realizes her true nature.

Takeomi Kuroiwa
Takeomi was Yoriko's classmate in elementary school for several years, although he often transferred because of his father's duty. Both of them still remember each other. She noted that he never talked much but had a strong presence and was incredibly athletic.
