A student of Abydos High School, and the grouchy secretary of the Abydos Countermeasure Committee.

One with many complaints, Serika is the type hesitant to show her emotions, and a Tsundere.
Despite her daily habit of saying "It's fine if this school goes bankrupt", she has a deep love for her school and works tirelessly behind the backs of her clubmates to pay off her school's debt.
