Claymore should definitely be on this list, altho I also definitely agree with seraph of the end. Lol

(claymore is sadly super unlikely to get any love, ever, but the anime and the Manga had great moments that never got expanded upon. I like to think of it as one of the strongest female leading stories, with crazy powersets. It's worth a watch, and a read, if you've never heard of it... But ive also heard the creator has left it dead in the water, at this point.)
