Plot
During the closing years of the civil war period and uneasy reign of Toyotomi Hideyoshi, when men high and low scramble to follow conventional propriety so that they don't attract undue notice (or death) to themselves, there is one very bizarre individual who is known for his legendarily outlandish and wild personality, physical appearance and behavior. This series traces the dramatic adventures of Keiji Maeda from personal conflicts with his adopted Maeda family, brave combat exploits, travels to the capital, and relationships with famous existing figures such as Iyeyasu Tokugawa, Rikyuu the tea master, and Hideyoshi himself, to experiences with the foreign and Japanese Christian faithful.
