Natsumi Betsuki

Serving as the dedicated homeroom teacher for class 2-A, this instructor is affectionately known by her nickname, "Becky." Although she possesses a youthful appearance and a seemingly lighthearted demeanor, she maintains the maturity of a true adult. However, her students must remain wary of her unpredictable mood swings, as her sudden shifts in temperament have a knack for plunging the entire classroom into moments of deep despair.
