Yuzuki Hazama - 間柚希

She has been [Futami's](https://anilist.co/character/298294/Nana-Futami) best friend since their school days, and although she works in a different industry, she is a good friend of hers. She is [Mizuki's](https://anilist.co/character/356304/Mizuki-Hazama) older sister, and Futami calls her "Ha-san" just like her younger sister.
