Got the March 2010 issue of Heavy Metal and found this AWESOME graphic novel. I'm having trouble finding information on it though. I'm wondering how many issues there have been so far, and which ones have been collected into trade paperbacks.

The setting and story is wild, as is the artwork. I'm falling in love with it.

so i have watched he anime i really liked it the most or major fanbase is the female gender i am the only guy i know who likes it and it would be considered a manga not a comic for people who dont know the difference but it is better than twighlight and the best part is at the end which is totally epic just i am not sure about the number of issues but do know that the series is totally worth the time and suprised to stumble across this series here glad to see another fan
