Yotoden: Chronicle of the Warlord Period, originally released in Japan between the years 1987 and 1988, consists of three OAV episodes--Chapter I: Break Out; Chapter II: Demon’s Cry; Chapter III: Flames of Anger (Emotion). Each episode is approximately 40 minutes in duration, making a total of about two hours. In 1989, the three OAV episodes were compiled into one volume--Wrath of the Ninja: The Yotoden Movie. This compiled version is only about 90 minutes long, painfully cutting out a chuck of the great original footages in exchange for a small amount of new, but nevertheless, mediocre scenes. In addition, for North America, this compiled version was only released in its horrendously dubbed format. In conclusion, if you haven’t seen the anime yet and want to, please watch the OAV episodes first; can’t stress that enough. (Ironically enough, I had actually watched the movie version first, so you can imagine my ecstasy when I discovered the actual OAV episodes.) Thanks to Bishonen no Miko’s very comprehensive coverage of the series on her website, lazy people like me can just point to the link and say: “Please visit Sakon no Miko's Yotoden Hall for all the Yotoden essentials, including a complete synopsis of the series.” ^_^;
