Naruto

Hard to choose only one... maybe Fushigi Yuugi. And why, hm... Because it take place at the ancient China, and, of course, it would be great to meet the characters. (Mainly with Tasuki )

d.gray-man.........

Pokemon!

Hands down
Seriously. Whats better than not going to school and traveling allover the world with your trust worthy pokemons and friends.
Not to mention you never age. lol

well considering my age I'd prolly go with Robotech.

i would definately be in Shugo Chara
why well cause i would have would be self
and thats just to awesome'
life would be different
a new txist

I think Pokémon is a good response. World like Naruto and Bleach sound fun at first, but then there's all these people dying left and right. The Pokémon world would be a lot like this one, where we can still play video games, watch anime, etc, except that we'd also be able to raise our own Pokémon.

Shugo Chara would be fun too, but it's probably less cool unless you find other people with Guardian Characters. After all, normal people wouldn't be able to see them, so it would potentially be just you and your Guardian.

the world of mermaid melody would be nice

but also Shugo chara would be fun to have a own guardian chara ^^

Vampire Knight...I wanna be a vampire hunter :X

I will go to Narutoland!
So i can kill some characters and make Kakashi sensei mine. jajajajaj XD

the world of dears so i can have one so i can pound her as much as i want and by pound i dont mean with my fists lol

Pokemon 'cause I get to play with pikachu :"D ....and have him electrocute anyone I don't like :3 heh heh

well if that fails...

Naruto so I can learn the forbidden jutsu and become immortal :3

Tower of Druaga

Cause i rly want to defeat that monster.

Either:

Gintama : because everything is funny and interesting. And it has Gintoki & Hijikata xD

Bleach: The fact that your soul lives on is just amazing and there's Ichigo and Byakuya =]
