Yeah, it does not give results for people named ひなこ. Maybe you gotta search using the kanji version of her name. I tried 森日向子 that I found on some JAV site, but no results either. This site might be not very up to date.

I tried with just the last name 森 (mori = forest) and there were about 5 pages of results (lots of duplicates) but none of them were Hinako.Yeah, it does not give results for people named ひなこ.

some of the problems are, some use Chinese characters for Japanese, sometimes you cannot see the difference, and a different search gives different results,This site might be not very up to date.
