On the outside, she is a cute and outgoing girl who is playful with her friends, especially [Keiki](https://anilist.co/character/135801/Keiki-Kiryuu). She can sometimes be childish and jealous when Keiki is around other girls, especially [Sayuki](https://anilist.co/character/135802/Sayuki-Tokihara). She does not get along with Sayuki and is always picking on her and the same goes both ways.
~! However, on the inside, Yuika is actually a huge Sadist/Femdom. She wants to dominate Keiki and wishes for him to become her slave, the polar opposite of Sayuki. !~
