This is a Japanese-language magazine about anime.
Hot chicks in underwear and swimsuits; what more could you ask for? There is some series information here but who cares, when you've got pictures of busty girls topless, slithering all over one another, wielding battery-powered implements (okay, that part was pixeled out, but it's still there!)? You don't want this book for the series information. You want it for the girls lying around in their panties and bras.
There is in fact a good deal of series information in this book, including screen caps, character bios, interviews with staff, and a fairly extensive goods catalogue. All text is in Japanese.
