Japanese name:

横島 ナルコ

Naruko Yokoshima is a teacher at Ōsai Academy, who happens to be the advisor of the student council. She is incredibly perverted, even more so than Aria and Shino, and aggressively seeks out younger guys, including her male students. She is often portrayed as unreliable and useless from the point of view of an educator.
