After the death of Nobunaga and heir Nobutada, Shibata Katsuie, the chief retainer of the Oda clan, summons Oda's retainers to the Kiyosu Castle to determine the new successor. At the castle, Gou sees a little boy accompanied by Hideyoshi's mother Naka. At the meeting, Hideyoshi declares that Sanboshi, the little boy who is the son and heir of Nobutada, is the most eligible successor, brushing off Katsuie's assertion to make Nobutaka, Nobunaga's third son, the successor. On that night, Ichi decides to marry Katsuie in order to thwart Hideyoshi's ambition.
