An anime-style illustration of Tachibana Mizuki, an original female Japanese teacher with black hair tied in a ponytail, neatly trimmed bangs, and calm blue eyes. She wears a navy-blue competitive swimsuit with a white rash guard over it, maintaining a modest yet sporty appearance suitable for swimming instruction. Standing by an outdoor school pool under bright summer daylight, she demonstrates swimming techniques with one hand while keeping a natural posture with the other. The background features clear blue pool water, the poolside, and glimpses of school buildings and fences. Her expression is gentle yet serious, with a warm smile as she instructs students. The artwork emphasizes a clean, refreshing summer atmosphere with soft lighting and vibrant colors, capturing a wholesome and professional teaching moment.
