Well, I watched Hyakka Ryouran again and read over my history glossary and this setting should be somewhere around 1570s-1597 or so in Japan, if it wasn't because of the fantasy setting overall, I would have raged quite hard at the 'naming' of the characters, and the fact they appeared in the wrong era, fighting for the wrong persons. (namely Yubei, because this guy appeared sometime before/after that era) . Dear, I wonder how would the official release version look like, according to the info, there is a DVD version and a TV version, both are animated entirely differently.
