Page I Chapter I
A long time ago,Pokemon and People lived in separate worlds.
Pokemon was in a nice world.Humans were too.
But suddenly,the peaceful moments were broken.
A great forced sent the two worlds hurling against each other.
But the two worlds weren't destroyed yet.
They combined,and all were dazzled with the sight of Pokemon and People
crowded in the world they were living in.
Pokemon were very kind creatures to their kind.
but now,in this mixed-up world of theirs,they couldn't find their friends anymore.
Separated....Separated from their friends.
Humans,on the other hand,got much ideas for Pokemon.
For them,for now,they were just tools.
but a little longer,
The Pokemon fought people because of their greed and badness.
