I couldn't find volumes 7 through 9, sorry! But the link for volume 6 leads you right to the Amazon.com page.
PERFECT GIRL Vol. 6-9
What happens when the four best-looking guys in school move in with the least popular girl in school who can't stand beauty or being touched? Especially when those four boys can live in the girl's aunt's mansion for free if they succeed in getting her to dress in pretty clothes and stop watching and reenacting horror movies practically 24/7?
That's the basic premise of the series and Tomoko Hayakawa's results, twists and turns are hilarious! Unfortunately, it's hard to get all the volumes out so far, but if you have a chance, take it!
