Personal Favorite....Beyond the Boundary

All of these contain at least a slight spoiler, so if you can take my word for it-just go watch this show, link for the series at Crunchyroll is below. If not here's a review of the first three episodes, the OP, a clip, the 'dance number' (which is becoming a tradition for Kyoto Ani) and a bonus-the english Dub trailer. Enjoy.
