Hazel Kujikawa is your typical schoolgirl but one major flaw: high testosterone. By the age of 17, her estrogen levels had been lowered—effectively making her a masculine woman (albeit not a herm). Her most defining features are her bushy unibrow and thick arms, scaring off potential bullies. She has outstanding strength due to her time at the school gym and is usually seen in a tracksuit. Despite a threatening appearance, she is soft-spoken and proud of her flaws. She can be a little brutal.
