Yoriko Kosaka

Finding Out About Her Transformation
Going into the ladies' restroom, Yoriko pukes out the food she ate. Upon washing her face, she saw her right eye becoming ghoul-like. Knowing fully well she'll be killed if anyone saw that, she covered it with her hand when Touka. She retreats to the nurse's office to place a medical eyepatch over it.

Suspecting of her best friend becoming a half-ghoul, Touka asked her about it, causing Yoriko to cry believing she's going to report her to the CCG. Lucky for her, she has no intention of doing this. She reveals to her of being a ghoul to make it even. Yoriko cried, realizing that she's unknowingly hurting her with the food she made her eat. Touka tells her that she ate her food because she loves her. The two then shared a hug.
