5DL at the moment...
Moon and Blood vol.3 is free on Amazon now. It can be read with Kindle, Kindle fire, Kindle for iPhone/iPad, Kindle for Android.
The free campaign is from today (16th 0:00) - 20th 23:59 Aug., Pacific Standard Time
It for everyone;
If you've read Moon and Blood English version(e-book) already, you'll find more fine and crispy images in this edition. (The resolution is about 1280X900)
If you'd not try the series yet, you can look the manga. Then if you were interested in this series, - buy and read English edition. :)
If you read Japanese - you enjoy reading this free manga, and more - It has some omake(extra), the first drafts of the main characters' profile (the one I showed my editor) in this time. I think it would be interesting reading, especially if you write/draw manga.
