Ibuki Fuuko♀

Fuko is a first year student at Hikarizaka High School. She is introverted, typically staying to herself as a result, and is often seen carving starfish out of wood with a small knife that she later gives to others as presents. She is usually so engrossed in this work that she is oblivious to her environment and those around her. She talks about herself in third-person and is regarded as a bit of an oddity by some of the other characters in the story.
