When Pioneer released AKIRA DTS Sound Edition in japan back in December 2002, it also released a limited edition that was bundled with a slipcase and a bonus disc containing the complete storyboard and hundreds of production stills like backgrounds and layouts. It soon sold out, but thanks to Amazon Japan marketplace, I found that someone was selling its copy at a bargain price. Even I already owned the AKIRA Special Edition DVD Box set released by Bandai and the Spanish one, just for the bonus content on this one, its worth the money.
