Konami Amanatsu is a supporting character in the anime Makeine: Too Many Losing Heroines! She serves as the homeroom teacher of class 1-C at Tsuwabuki High School, where she teaches social studies or history. Despite being an adult, she has a youthful appearance that often causes her to be mistaken for a high school student. Her personality is defined by clumsiness and absent-mindedness; she frequently drops stacks of printouts she prepares for her lessons and sometimes forgets that the protagonist, Kazuhiko Nukumizu, is a student in her class. She is openly dissatisfied with being single and frequently complains about not having a boyfriend, and she shows jealousy toward the school nurse, Sayo Konuki, who is popular with men. Amanatsu and Konuki were classmates in the past and maintain a friendly rivalry. Her role in the story is primarily as a comedic teacher figure who interacts with the main characters in school settings, providing lighthearted moments. Her motivations center on her desire for romance and her frustration with her own perceived shortcomings. She does not undergo significant development but remains a consistent source of humor. She has no notable special abilities beyond her teaching duties.
