Okay, BLURB TIME (OMG I love that word: BLURB~! ^^):

Twenty years after the triumph of Ash Ketcham as a Poke'mon Master, a nuclear war broke out throught the regions. As all wars do, it ended at one point, three years after it began. For eleven months, nobody was allowed out to travel as a Poke'mon trainer, and when they did allow it, the legal age was raised to sixteen. This is because the radiation fallout from the war changed Poke'mon, but did not affect humans.

It's fifty years after this that a young boy named Lucas Pockent, age sixteen, sets out on his Poke'mon journey with his new poke'mon; a female Pikachu. Not too far down the track, Lucas falls into a pit, and when he comes to, he feels a heavy weight upon him. A girl with pikachu ears, and a tail...

Follow Lucas and Pikachu, now nicknamed Pik-san, on their epic journey to become the next Very Best!
