This book continues the spiral down into "hentai is ok" territory, which it's not. And the fact that so many of the women of this book want to draw it is unrealistic and pretty much an otaku fantasy at this point. I think the books were good when they were focused on Najimi trying to improve her art...
This one was OK, it starts to ramp up to good then it just falls like a coaster. THey also snuck in the homophobic "joke" of turning a gay person straight.
