I've only just started reading this, so I've only read the prologue...but I thought I might comment anyway.
I'm a little confused at this point, having never played the game, but I'm sure it'll get more clear as I read more. I really liked the way you described the settings and emotions and even a little bit about the two pokemon. I hope they'll have interesting personalities as the story goes on.
I only saw one typo, here:
Through this, sent me a equivocal answer.
It should be 'an.'
Not much else to say right now as I've only barely started reading, but I'm interested to see where the story goes!
