Saijou Hifumi

"Be careful, girls can lie."

The foster daughter of the esteemed family of Saijo in Yakotami-cho. Her father's friend adopted her after her father's death.
As a proper Ms. Saijo, she is of good character, with outstanding grands, good relationships, and a great reputation in school.
She plays the role of an impeccably talented girl.
However, the truth is that she is a naughty girl and she wears the mask of a top student, only taking it off in front of her true friend Sora.
