Miho Amakata is a supporting character in the Free! series, including the film Free! -Take Your Marks-. She serves as the homeroom teacher of Haruka Nanase and Makoto Tachibana at Iwatobi High School, where she also teaches classical literature. In addition to her teaching duties, she acts as the club advisor for the Iwatobi High School Swim Club, overseeing the team's activities and providing guidance when needed. Her background includes a previous career as an office lady in Tokyo, though the specifics of that period remain largely unknown to those around her. Miho is known for her kind and gentle demeanor, which quickly earned her the affectionate nickname Miss Amachan from her students. She has a habit of quoting the words of great historical figures, often incorporating those sayings into her interactions. Her personality makes it difficult for others to refuse her requests, a trait that proves effective in her role as an advisor and teacher. Throughout the series, she remains a steady and supportive figure, offering quiet encouragement to the swim club members without seeking attention for herself. Her role in Take Your Marks continues this pattern, as she helps facilitate the students' transitions after graduation and maintains a calm presence amidst the changing circumstances. While she does not undergo a dramatic personal development arc, her consistent warmth and reliability make her an integral part of the school environment.
