Bekki, Natsumi

戸次菜摘

She is the homeroom teacher for class 2-A. Despite her youthful appearance, she enjoys playing tricks on her students and maintains a cheerful demeanor. She is approximately forty years old and has never been in a romantic relationship.
She experiences frequent mood swings; at one moment, she is a bright and cheerful woman who openly confesses to her students about the perverted things she has done to herself, but the next, she becomes gloomy as she feels the weight of being single and lonely. She is also an otaku. Her students often refer to her as "Around Forty," but when she gets angry, she transforms into the feared "Gaia."
