What I've said about Kaori for as long as I can remember is...
She's never really been one of my fav members because she's not what I look for
in an idol... But she's one of the H!P members I always thought would make a fascinating friend; someone you'd really like to know personally, talk about random stuff with and such. She seems so down-to-earth. Actually she reminds me of the kind of creative and weird (in a good way) friends that I used to have in school.
Also, loved her in the old Utaban episodes, and she's one of the most legendary dancers in Hello! Project.
