Souten Kouro’s story is based loosely on the events taking place in Three Kingdoms period of China during the life of the last Chancellor of the Eastern Han Dynasty, Cao Cao (155 – March 15, 220), who also serves as the main character. The Three Kingdoms period has been a popular theme in Japanese manga for decades, but Souten Kouro differs greatly from most of the others on several points. One significant difference is its highly positive portrayal of its main character, Cao Cao, who is traditionally the antagonist in not only Japanese manga, but also most novel versions of the Three Kingdoms period, including the original 14th century version, Romance of the Three Kingdoms by Luo Guanzhong.
