I haven't seen anime in a long long long time right about now. So I'm falling out of it. But I've seen numerous scans on this anime in the gallery and I'm interested to see what it is about. So can anyone fill me in with a summary on this particular anime?

Sorry if this is in the wrong section >__<;;
It's just that this anime is really interesting and I need a quick review on it to see if I want to see this.
