如月 みたま

A teacher at the protagonist's school with a license in healthcare...in other words, she's the school nurse. She is one of the few women at the all-boys' school, and her calm and gentle personality makes her very popular. This makes her the object of everyone's admiration on the surface, but in her private life, she is a total failure. She is a good-for-nothing older sister lacking in feminine energy, but she greatly excels in making others spoil her. Even today, she spends her time lazily relying on her beloved Na-kun (her nickname for the protagonist). [translated from official website]
