Not bad... I think that this is pretty original, with an experienced trainer starting all over again. Watch the punctuation, though; sometimes you put them in the wrong places, or skipped them out entirely. The description could also be improved, with details as to what people and things look like etc.
Have fun writing!
EDIT: Fine, mr_pikachu... it's not original.For your information, I haven't watched the anime in years, not since the Orange League or something.
