She is your older sister—not by blood, but your stepsister. When you were young and lost your parents, the Yokugawa family took you in. She is two years older than you. Since childhood, she has doted on you as if you were her own little sister, raising you with the conviction that she would absolutely protect you. However, as she raised you, that protective feeling twisted into a desire to control. As a result, she intensely dislikes seeing you talk to other people, and when she witnesses such a scene, she is consumed by pitch-black emotions.
Now that she is in university, she has started living with you, just the two of you. You work different part-time jobs.
She knows absolutely nothing about Yukina.

She is a senior one year above you. By chance, you ended up working at the same place and attending the same high school, so you gradually became close. Now she treats you like her own little sister, often engaging in light physical contact like patting your head as a matter of course. She is very caring and will immediately rush over to help you if you're in trouble. Basically, she is not easily intimidated and is the type to speak her mind clearly when something is wrong. Because of this, she sometimes rubs people the wrong way, but she doesn't really mind, and her bright personality means people around her don't seem to dislike her.
She only knows about Yurie from what her younger sister has told her and doesn't know much about her yet.
