Aiko Hatayama

Aiko Hatayama (also known as Ai-chan-sensei) is a supporting/main character in Arifureta: From Commonplace to World's Strongest. She is a high school social studies teacher from Japan who, along with her class (including protagonist Hajime Nagumo), gets summoned to the fantasy world of Tortus.

She's depicted as a petite woman with a youthful, childlike figure, short brown hair, and striking green eyes. She often wears professional teaching attire like a blouse with a bow.

Personality-wise, Aiko is a very caring, responsible, and compassionate teacher who deeply prioritizes her students' well-being and safety. She's idealistic, morally driven, and sometimes dense about romantic affection directed toward her (often mistaking it for friendliness). In the story, she earns nicknames like the "Fertility Goddess" or "Goddess of Victory" due to her unique abilities and positive influence on people.
