i've watched about 20 anime and here they are my favorites:
-D. N. Angel
-Bleach (of course XD)
-Kateikyou Hitman Reborn! (with my dying will!8059, D18 <3)
-D Gray Man(Tillen *_* Lavanda)
-Nabari no Ou
-Kyo Kara Maou (helps to escape from daily problems :)
Yes I have. It reminds me of those little books where you read the 10 different scary story's. I loved the animation style and I'm very disappointed that the Author hasn't written anything else like it.
