Miki Yagisawa is a supporting character in the anime I Made Friends with the Second Prettiest Girl in My Class. She is a twenty-five-year-old first-year homeroom teacher at the high school attended by the main characters. Despite having been a teacher for three years, the role of homeroom teacher is new to her, and on the first day she nervously bit her tongue in front of the class. However, her naturally cheerful and approachable personality quickly won over her students. Her background as a relatively young and inexperienced educator shapes her role as a supportive figure who oversees the classroom dynamics, offering guidance when needed. Her motivations revolve around fulfilling her duties as a teacher and fostering a positive environment for her students, though specific personal goals are not elaborated. As a homeroom teacher, she interacts with both Maki Maehara and Umi Asanagi in a professional capacity, but her relationship with them is primarily that of a teacher rather than a close personal confidante. The character does not undergo significant personal development within the story, and no notable special abilities or unique skills are attributed to her beyond the responsibilities of her teaching position.
