ah where to begin with loveless? this is a manga thats different from others somehow in a profound way, it shows a really deep character development that hasnt even been fully revealed yet. There's alot to look forward to in this manga and if your a fan of anime or manga in general it contains something for everyone (although girls usually are geared towards it, i have found many of my male friends enjoy it for its psycological themes) you have comedy,action,romance,somewhat of a mystery..and alot of characters that fit into a personality that is anything but clique. They artwork itself is worth looking at, with alot of two page full color spreads done in high detail. Even the pages on the inside are well drawn out with a style that is only yun kouga's. If you enjoy manga that has some gore or intense battles this is surprisingly good for that considering there's a large (and definately bloody)battle in almost every volume. Also
it is very thought provoking, it will most definately make you think and sympathize with the characters on an emotional level. Although a drawback of this manga is the long wait, for the english release it has been almost two whole years, as for the japanese its still not progressing much faster, a second drawback is the amount of yaoi (which can bother some people) otherwise
you should give it a read, the first 2 volumes are actually slower and less involved, when it hits volume three most of the main characters are introduced and the story moves in a more interesting direction.
