She, along with her twin sister, older sister and mother all bear great resemblence to each other. The only way to distinguish her from her sisters are her wine-colored hairband and her sailor-like outfit. The outfit may also be the same one that Wakaba once wore in Summer Radish Vacation.
Compared to her twin sister Futaba, Kazuha is a reserved person and shy away from sex in general unless coerced by Futaba. Like her, she has crush on Makoto but isn't given a chance to confess due to Karen being around.
She doesn't appear in the anime and makes an appearance in a certain harem ending and is mentioned in one of Hikari's ending. In the harem ending she comes to Makoto's home and finds her sister there and all three of them are planning to "hang out". Makoto says "shall we get going" and the game ends.
In Hikari's ending she along with her sister wants to have sex with Makoto but Makoto mentions that these first years don't want Makoto himself but are just curious about sex.
She and her twin sister are more involved in the story and have endings dedicated to them.
