Toward Himeno
Just one of the masses. Honestly annoying. I have no interest in you at all. Could you stop with the homemade sweets? That sugary perfume makes me want to turn my nose away.
Toward Kaito
You're pretty cool.

First person: Hime (referring to self in third person) Second person: -kun♡, -chan♡
Personality: Little Devil / Flirtatious
Fell in love with Haku at first sight during the entrance ceremony. Firmly believes she is the only one worthy of him. The epitome of a calculatedly cute girl who makes men want to protect her. Wears a peach-scented perfume. Acts dumb, but is smart enough to get into a top school. Acts frail, but is strong enough to grab bugs with her hands. A calculated flirt, but so cute that men dote on her. Popular with both genders. People say she and Haku make a good match.
Toward Haku
I love you ♡ Please date me ♡ Hime is your number one, right?
Toward Kaito
You're the most handsome guy after Haku-kun ♡ I guess I could date you if you want?
