Daiya is an anthropomorphized diamond. He was a piece of coal who had been living under the shadows inside his lonely cold cave, watching other gems get out and succeed in the world, as he was left behind watching from afar, thinking that could never be him. Until one fateful day, he decided it was his time to finally shine and join the others, so he got himself out of the cave and started to explore the real (virtual) world, slowly sharpening his skills, and growing to finally become a brilliant diamond, as he currently is referred to as a "diamond in the rough".
