Suzume's friend and classmate. She has an unrequited love for Mamura. Initially, she believes Suzume likes Mamura so Yuyuka tries to get close to him using Suzume. Her plan falls through when Suzume confronts and reprimands her for her actions; shortly after they become friends.
Yuyuka's true personality is very blunt and unforgiving which she believes causes friction with people, which is why she hides behind a "cute" exterior that is friendly and outgoing in order to make friends. Suzume is the first friend she makes who knows her true personality.
