Yamamoto, Nanako

山本菜々子

She oversees the class adjacent to Tsuchida's. Tsuchida fell in love with her at first sight.
Yamamoto-sensei is a female teacher at Hanamaru Kindergarten. Although Tsuchida likes her, she fails to realize that men would fall for her. She teaches the first-year students of the Peach Class. She seems skilled at sewing, having repaired Tsuchida's apron and the ear of Koume's stuffed panda-cat doll.
