Nanako Yamamoto

As a dedicated educator at Hanamaru Kindergarten, this talented teacher oversees the first-year Peach Class. Though she possesses a gentle, nurturing nature and impressive sewing skills-evidenced by her repairing Tsuchida's apron and Koume's favorite plushie-she remains completely oblivious to her own charm. Despite Tsuchida’s immediate and intense infatuation with her, she lacks any awareness of the romantic feelings others harbor, maintaining a purely professional focus on her students and neighboring classroom duties.
