Saving Ms Midnight

Nemuri was a very playful, flirtatious, and perverted person with an unpredictably serious and temperamental side to her. She got angry whenever someone interrupted her or insulted her, and, when it came to insults, she was especially sensitive about her age.

Nemuri had no shame for dressing or acting sexually in front of young students and appeared to act on whims most of the time. When she accepted Mashirao Ojiro and Nirengeki Shoda's request to resign from the tournament, she commented that their naivety "turned her on." She was also excited to see the chivalry displayed by Eijiro Kirishima during the tournament when he shook Tetsutetsu Tetsutetsu's hand. Her love of "youth" was also a reason why she got angry when someone mentioned her age or called her old.
