Question on Ayu's Biography
 

Because there have been so many mistranslations in the biography of Ayu (i.e the part about her having an "older brother"), I won't be disappointed if there isn't a true answer, as I understand that the translation may be pretty vague.

Sorry, but when she says "things," does she mean material-wise (for example: she respects those who may have the latest shoes and she doesn't), or by "mental" (can't think of the right word) possessions (for example: she respects those who have a strong relationship with a love or friend that she doesn't have)?

yeah, it's vague...

and about that brother: funny, I read somewhere she had a sister.... X_X

I thought she's talking about mental things. (ayu gave a similar answer when she was asked about her ideal type of man in one of the MCs of the AT05.)
I think it's maybe like, um... When she talked about Nagase once, it seemed that he's more easy-going. Not worrying so much or whatever. Maybe that's what she means. Like having a balance. Or maybe in order to "learn" something from the person.

Maybe if we knew how she put it in Japanese, it would be easier to figure out the real meaning...

Did you ever think that it could possibly be an and/or situation?

I agree with aga-chan. It probably has something to do with having a different personality,strengths or outlook.
Or it could be literally. Depends on the translater and context, but I personally think it was the former.
