Mizuki Haruka

The most popular teacher in the school just loves playing the piano

She is the music teacher and assistant homeroom teacher for Class 2-5, where Kazuhiro Kijima has transferred. She often takes over homeroom in place of their homeroom teacher, Kodama, who is not very enthusiastic outside of class. A beautiful woman with a nice body, she has a bright and friendly personality, which makes her very popular among the students. In this respect, she is the complete opposite of Mr. Kodama. Is it too much to say that her slightly childish personality is part of her cuteness? Although she is a skilled pianist, having attended a music college in the country, she can sometimes be more modest than necessary. However, she does love playing the piano. It's not that she's good at it, but rather that playing the piano is fun in itself. That's the kind of teacher she is.
