No real improvement from the first volume. Just too focused on the hentai/ecchi, and not enough on the overall monster girl characteristics

Honestly as someone who was thinking of attempting to write a story involving monster girls, I bought both volumes in hopes for more information outside of what has been seen in manga, light novels, and anime... But this is basically just information of monster girls in regards to hentai and ecchi. The info I was hoping for was minimal at best. It's got good art, nice hardcover edition, but the book just wasn't for me or my needs.  I'll go through volume 2, but my expectations aren't really there.
