Looking for a American Manga?

Okay the Manga was made in America so you read it like an American book. Two boys got on a plane to Japan/Tokyo and there they bought some robot girl that compatible to games. The boy lost his drawing book in one book and some girl found and brought it back to him. And the other boy who could speak L33t and always got the real word and video games mixed up. And so he meets some goth girl who always plays around with him
I think I made it confusing. >.< Anyway if anyone knows what I'm talking about then please tell me!
