High School of the Dead will have a season 2. Hehehe, so excited.
My first anime.... most likely it would be one of those children's literature types like Princess Sarah, Heidi, The Secret Garden, etc.
Then comes Sailor Moon, Dragonball Z...
More shojo anime like: Magic Knight Rayearth, Card Captor Sakura, X, and other CLAMP creations.
More shonen anime like: Rurouni Kenshin, Yu Yu Hakusho, etc.
Mecha: Gundam (a lot of them), Escaflowne
Children shows: Pokemon (some episodes/movies occasionally), Monster Rancher, Digimon (4 seasons!)
Other shows: Cyberteam in Akihabara, Trigun, Trinity Blood, Bubblegum Crisis, You're Under Arrest, Oh My Goddess, etc.
In the recent years: Fafner, Heroic Age, Blood+ (I'm so proud of this, I watched it raw!), Kuroshitsuji.
My most recent ones were already listed earlier. Oh yeah, I forgot Sword Art Online.
I would definitely be missing a lot of shows that I can't remember right now. hehehe.
