"Okay. Starting tomorrow I'll try again! I'll become a new me..."
Ambiguous Gender Identity: It's strongly implied that Hazumu was a trans girl all along without realizing it, and that may have been the reason behind the Gender Bender in the first place. She doesn't protest at all about becoming female and seems to be much happier as a girl than she was as a boy.
Girly Girl with a Tomboy Streak: Despite her femininity, she keeps some of her traits from having spent her entire life a boy (such as preferring boyish clothes).
Innocent Fanservice Girl: Justified as s/he just turned into a girl and is therefore unfamiliar with how s/he should act, such as using her skirt to cool his/her legs, and asking Asuta to measure his/her bust size.
Ambiguously Bi: Not enough is shown about their past to know if Tomari is lesbian, bisexual, or if Hazumu is her one exception. She has Ship Tease with Hazumu as children and doesn't mind when Hazumu is revived as a girl.
