工藤野乃

陽一没有血缘关系的妹妹，日奈乃的双胞胎姐姐。 容貌和性格都无可挑剔，加之还是田径部的种子选手，可说是校园偶像。 进入这个学校前还分开居住，现在则搬过来和陽一共同生活。

Nono is a 1st year high school student. She is the youngest of the Kudou twins, and Youichi's little sister. Hinano and Nono are Youichi's stepsisters by marriage, their mother was the wife of Youichi's father, as such they are not related to Youichi by blood. Several years ago, when Hinano and Nono were but children, they were sent to live with their aunt. Said aunt is now getting married, which made Hinano and Nono decide that they would move back in with Youichi, and that they would start their high school days at the same school which Youichi attends.
