Under the stone world sky

Before the petrification, Ayame attended the same school as Senku Ishigami and was one of the few students who could match his intelligence. While Senku was the president of the Science Club, Ayame led the Psychology Club. Despite knowing of each other, the two never actually spoke. Known for being quiet and reserved, Ayame rarely interacted with others unless the topic involved psychology, statistics, or mathematics.

Born into a wealthy family, Ayame was raised by a scientist father and an anesthesiologist mother. After her mother's passing, she was left with only her father before humanity was turned to stone.

Years later, Senku and Taiju discover Ayame in the Stone World, setting her journey into motion. As she joins the Kingdom of Science, the story follows her role in rebuilding civilization.
