Wow! Nicely done!
First impressions:
* Video trailer = Impressive! Professional anime look and feel. Very classy and I'm totally blown away.
* Story = Intriguing. Love a lower caste with magical potential. I like to root for the underdog, so the story premise I already love.
* Programming = Cool! Love the highlighted character so you know who's talking.
* Art = Beautiful. From title screen, logo, character sprites, background.
