Mei Ogawa is a first-year student at Seimei High School who becomes a member of the schools kendo team. She is identifiable by her medium-length brown hair and blue or green eyes, and her demeanor often reflects a gentle but uncertain disposition. Her initial involvement with the kendo club was not driven by a personal passion for the sport but rather a social desire to spend time with her friends who had also joined. This motivation proved fragile when the teams teacher, Tadaaki Hayashi, imposed a training regimen so strict and harsh that one by one, her friends quit the club, unable to endure the rigor. This series of departures left Mei as the sole remaining first-year girl on the team, a position that fostered deep feelings of isolation and self-doubt.

Isolated and lacking confidence in her own abilities, Mei became increasingly fearful of her intimidating instructor, Hayashi. Her anxiety reached a point where she firmly resolved to leave the kendo club herself, planning to tender her resignation immediately following an upcoming practice match against the Muroe High School team. She saw no future for herself in an activity that had become a source of stress rather than enjoyment. Her pivotal turning point occurred during this very match. While watching a bout featuring Tamaki Kawazoe, a remarkably skilled and natural kendo practitioner from Muroe High, Mei experienced a profound shift in perspective. She was captivated not by the victory but by the sheer, exhilarating skill Tamaki displayed and the apparent joy with which she practiced. This moment redefined kendo for Mei, transforming it from a punishing obligation into an activity that could be genuinely fun and inspiring.

Inspired by Tamakis example, Mei abandoned her plan to quit and recommitted herself to the Seimei High kendo club with renewed determination. Her key relationship is, therefore, less with a specific character and more with the idea of kendo that Tamaki represents; however, her decision to stay directly ties her to her teacher, Hayashi, whose methods she must now learn to face. Over the course of her brief but significant arc, she develops from a passive participant dragged along by friends into a more self-motivated individual who chooses to confront a difficult situation. While she is not portrayed as possessing any exceptional or prodigious abilities in kendo, her primary strengths become her quiet perseverance and her newfound will to grow, even in an environment she once found unbearable.
