Saiunkoku: Characters' faces and names
The bios are mainly from the official site's characters page, as are the pictures. I've added the names of the voice actors. And since the show is set in China – a fantasy version of the Tang period, I think – I've added the Chinese pronunciation of their names. This helps me, anyway, since I know Chinese a lot better than I know Japanese. And in any case, the sounds of the names differ more in Chinese.
