Naruko Yokoshima

Serving as the student council advisor at Ōsai Academy, this educator possesses a surprisingly lewd inner monologue similar to Aria and Shino. She harbors a specific attraction to younger males, frequently setting her sights on the school's male students. Despite her professional position, she is widely regarded as a deeply unreliable and incompetent teacher, often struggling to maintain the standard of authority expected of an academic instructor.
