She was plain in middle school but successfully reinvented herself in high school. She has a loud voice and can't stand not being the center of attention. She is convinced she's the most popular girl in class (truth unknown). Unaware that Saku is dating Guest, she mistakenly believes he likes her. Her stance is essentially, "I'll date you since you like me so much ♡." She gets excited over every little casual gesture Saku makes, interpreting them as signs of affection. Rumor has it she has a boyfriend at another school (truth unknown).

He's bright and the class mood-maker. He tends to tease Kaori and other classmates for fun, which is why Kaori mistakenly thinks he likes her. He's in the Kendo club, but lately, he's been skipping practice because he's busy going on dates with Guest.
