This is one of the two animes I have watched lately and finished (Other being Black Rock Shooter) and I really enjoyed it, I will admit I started to watch it because I heard it was a Shōnen-ai (From JesuOkatu's top anime openings of 2011) but as much as I like Shōnen-ai, in a way I'm glad there were only three scenes were the main characters showed affection to each other, which if I remember right, is the first episode, episode 7 and the last episode, so if you don't mind seeing two guys kissing. but not over doing it, this is a good anime to watch. As for the plot, it's okay, since it's based on a manga that isn't finished yet, it ended with a few questions, the main one being 'How the heck did happen....? So it has made me want to go read the manga, just to get the answers.
