Isako Toriumi

Serving as the relaxed language instructor for Class 2-F at Gekkoukan High School, this educator is best known for her immense passion for sweets, specifically everything except Mont Blanc. While she frequently clashes with Mr. Ekoda, she maintains a friendly bond with Mrs. Terauchi through late-night Mahjong matches. Though she appears easygoing, she is a cunning strategist who reportedly remains undefeated by secretly cheating against her less experienced gaming companion.
