I was planning to watch Sword Art Online but... Actually I think that's not really my kind of anime... Maybe I'll watch it later.
So I decided to watch "Tasogare Otome x Amnesia" (or, in english, "Dusk Maiden of Amnesia") instead. It was really great. It's a mystery/detective/semi-horror anime, with a beautiful chara design, perfect dubbing, and a brilliant storyline. And the soundtrack is just gorgeous. That's a pity this anime is not that well-know, because it'd totally deserve it. Anime like that are rare.
