Coolest episode 1 that あなた ever watched?(suggest atleast 3 :D )

Attack On Titan (The first time あなた hear that theme song *-*)

Durarara

Sword Art Online (While I hated the rest of the series the first 2 episodes are actually pretty good)

宇宙 Dandy (I'm obsessed with this series)

Soul Eater (the theme song is amazing and there's a lot of action)

Mirai Nikki (the theme song, oh my god ♥︎♥︎♥︎ And there's blood and violence, so I 愛 it)

Maria Holic (complete unexpected randomness. Plus, the opening is on drugs, I swear)

エンジェル Beats (complete epicness)

Higurashi: When They Cry (scared the living Hell outta me)

-Samurai Champloo (Epic fight scenes and 音楽 right in the first episode. That series was way too short.)

-Gurren Laggan (This one is an amazing series.. and the first episode is pretty awesome too.)

-Btooom! (Lots happens in the first episode if I recall correctly..)

-Deadman Wonderland (Super intense first episode and gory.)

-Attack on Titan (I had to re-mention it. That was the most intense and crazy first episode I have ever seen.)

-Guilty Crown
