Kotarō is a wild card who strives to perpetuate endless chaos. When his master hears of Ieyasu's retreat at Mikatagahara, he is ordered to assist Shingen with the pursuit. Although he does capture Ieyasu, Kotarō also kills Shingen to counteract the results. In a bid to spare their lives, Ieyasu and his men are forced to serve Kotarō and surrender to the Hōjō. During his time of leisure, Kotarō learns of Nobunaga's infamous "Demon King" reputation.
